I apologize if this isn't in the correct forum. I wasn't sure since it's dealing with two dif os's.
Anyways, my question is Can I access files on the android jellybean partition from inside of wp7? I would like to be able to play movies, look at pics in wp7 that are in the android partition.
Also, what about vice versa? One last question. Wp7 seems to run very quickly, but Android seems to run pretty slowly. I assume its because it's running from the SD card. Is there any way that can be sped up to run at normal (fast) speed?
--- edit:
is it possible to put android on the nand, and wp7 on the sd so that the android os would be faster?
So.
Yes, you can access files from FAT partition on WP7. Few file explorers allow you to do that, just have a look at them and check if Storage Card folder works. They also allow you to watch videos, view images and play music, but forget about playlist support, subtitles or anything complicated. We don't have software to do that yet.
Vice versa is not possible since WP7 uses its own file system which Android can't see nor use.
Android will always run slower because it's an unoptimized piece of sh- I mean software. But you can try ROMs which take advantage of EXT4 partitions using NativeSD method - these are noticeable faster, no more waiting for minutes for apps to launch. You can also overclock CPU and use higher read ahead value for SD card (SD Speed Increase from Market).
Putting Android on NAND and WP7 on SD is not yet possible. It might be when Magldr 2.0 will be released (and it won't be really that anyway), but we don't know when.
thank you
thanks for the detailed and thorough explanation. i see that you are also using a dual boot. how slow/fast does your paranoidjellybean operate? i'm going to look into ext 4 and cpu boosts. i guess i will have to reinstall/delete everything in my android partition to do an ext 4? and i guess if i go ext 4 wp7 won't be able to read it? i'm going to look into it. i will update this with whatever info i find.
---- edit
I'm going to try and use the roms you name in your signature area that you are using, and see if it works any better. what sd card are you using? I'm using a micro center micro sd class 6 16gb one. i'm getting a 8000ffff error in this wp7 rom when trying to get something from marketplace, and the droid is too slow. going to try the ext method for the droid. (can't dl apps on droid either!) so i will post what happens here.
---- edit
ok, i'm thoroughly confused by these instructions (somewhat vague in parts ) http://forum.xda-developers.com/showthread.php?t=1869673 Is there a video tutorial where it is shown what to do step by step to get a native sd setup for a dual booth with android sd and wp7? Do I just do it the same way I did before (install wp7, then reset / repartition, but instead of using fat32 i make a fat32 (how big) and an ext4 (or 2?) and which comes first (the fat or the ext) ? Afterwards, ALL partitions are primary?
i found this info for installing ext4. but do i create the ext4 BEFORE or AFTER i install WP7 ?
I'd say Paranoid JB is pretty fast using NativeSD (EXT) method. You will need to create an EXT partition first, but keep a FAT partition, because on EXT the ROM will keep only its own data and apps, the rest is still on FAT (just like now, but instead of data.ext and system.ext in ICS folder there is a partition just for those). Windows Phone 7 will not be able to read content of EXT partition, but it will not be needed, since there won't be anything worth looking at and all media files you will still keep on FAT. You will also have to make a backup of everything on your FAT partition because it will be lost, and fresh install will be necessary. You might want to backup your applications with Titanium Backup though.
For more information on partitioning please visit NativeSD thread.
I'm using a 8GB Transcend Class 4 card with 4GB FAT, 1GB EXT and rest (2.4GB) WP7FS. I don't have any errors with downloading apps on neither WP7 nor Android. Are you sure you entered that special code for Marketplace and logged into Google account on Droid?
furthermore
actually, i installed the hd20 rom you're using and had no problems with marketplace. at this point i have hd20 wp7 set up, activated, and working. i'm just trying to understand some of the more advanced information in the forums about setting up the ext4. i found some very technical instructions (edit: http://forum.xda-developers.com/showthread.php?t=534714 ) for setting up an ext2 with gparted via dos then upgrading it to ext4. i don't know if that will mess up the wp7 partition, and if i should have done this before i installed wp7.
i had already read the nativesd thread, and the extended threads from it. i'm afraid i'm just not knowledgeable enough currently to fill in the gaps of information i find in a lot of the instructions. but i'm not giving up.
---- edit update:
this has gotten way off the original topic so I've started a new thread with a diferent topic here: http://forum.xda-developers.com/showthread.php?p=31356468#post31356468

First off, to eliminate the flamers 1)I know you don't need to partition your SD Card (i've been running android on 2 SD cards for around a month now) 2)I know it won't make my device run any faster.
The question is though If i partition my memory card to have the 3 partitons: ext, linux swap, and fat32, will this mean that on the main part of the memory card that my windows mobile can see that i won't have all of the various folders that the Android OS creates (i.e: .android_secure, .bookmark_thumb1, rosie_scroll?
The reason i ask is i want to have my memory card as clean as possible so that within my windows mobile build that it is still very organized.
Thanks for any help you can offer. If you are going to reply simply to say use the search, I have, I've read and thank you very much, you can now move on to the next topic to type that.
I also have the same question.
How get clean memmory card from Android folders?
Or how to install Android in folder (sdcard/Android/all android folders)
Than my WM folders will use (sdcard/WM folders)
I second either of these as to keep my mem card tidy from all the android folders created and mixed up with my WM files.
Well since no one seems to know the answer or isn't willing to share, I am going to try doing this within the next two days and will report back on whether or not it works.
How would each OS know what partition belongs to it?

Nice to hear that! I think there is 2 ways:
with partition on sdcard
change Android install place to place in folder
Somone who build Android roms can try to change location where android install apps.

If you crate partition for linux (ext...) windows will not show, read and find it.Also WM will not read files on linux partition but I think that linux still will read both. Dono how it is on Android but in Ubuntu on PC it works.
SD partitioning works great!
This is how to create partitions on your SD card: http://forum.xda-developers.com/showthread.php?t=267475
I tried it - and it works. WinMo shows two storage cards - 'Storage Card' and 'Storage Card 2'. The first one is the Active partition - which is my Android partition.
When you are in WinMo and installing WinMo software, you are given the choice of where to install it - and it shows both storage cards. So in effect you can have all that is WinMo on one partition and all that is Android on another. Android is working nicely from its own partition.
I must say - this is the first time my Android is working sooooooo well. As well as my wife's HTC Desire device. It is a noticeable difference - the same Android build worked quite sluggishly before this exercise. It is either because I am using a freshly formatted partition, or because it has its own partition now.
My partitions were formatted with FAT32, 32KB unit allocation size. I am using ChuckyDroid ROM and currently testing this Android build Core_Droid_V.0.2.
Yeey ! " ... after action - satisfaction .. "
Hi,
last time i came in here unhappy with my stock HD2 on tmobUK android was just emerging on SD, now i came in here the other day WP7 is available as NAND and so is android....things seem to be a little confusing now, quite a few of these great ROMS are from people whos first language is not english so its quite hard to sometimes understand what they are explaining so i would be greatful if someone could answer somes questions, i have tried to read threads as best i can but some of them, well most actually are well into the hundreds within hours.
1) A lot of chefs describe NAND and SD, i know the difference between the two, but then they get mixed with magldr and NAND with ext4 etc etc..basically i want to flash the phones software to my NAND, i am assuming this is the best way to have it running at its optimum ?..so if i do this why would i need ext4 partions on the SD as well ? whats the benefit of it ?
2) i have also noticed that you can scan a barcode and have a link download a new rom to your phone and flash it, could i do this with ANY rom straight over the top of another without question ? and everything will be as it should be.
3) Does each ROM need to be set up in a different way?, this partly answers the previous question.
4) i flashed WP7 to my NAND (i think)..i was not happy with it and i had magldr installed, i just formatted my SD card to fat32 popped it back in and followed instructions to put [Feb 01][DL DesireZ v3.4][DL Data2SD/Ext4 v2.6][Nand/SD/MAGLAR] on to it.... it took me into magldr and told me to do a few things...did this flash to my NAND ? and did it do what was needed to the SD card regarding format or was it up to me to make certain changes to the SD card myself ?..the phone works and i can make calls, but all the apps that are stated to be in the ROM are not there, i cant find any GPS stuff and when i go to market place itsays its downloading an app but i can never see it.
As you can see i really am quite discombobulated with all this...i would love a easy reading guide that explains everything from A-B and all the terminolgy.
Thanks.
1. Many of these Android roms would swamp the entire memory of the EU HD2, so a workaround is to have partitions on the sd cards to store apps and data, leaving the system to run on NAND. When you update your rom, you just flash the system files and all app and data remains on the sd card.
2. The QR code just allows you to download the rom to your phone. You would still need to flash it AFAIK. (Heven't tried one of those yet). There are basically 2 types of NAND Android roms. One type use the more conventional flash type where you run an exe (daf.exe) from the usb flasher option on magldr. The 2nd (more recent type) packs the roms as zips which you can download and copy to your sd card and then using Clockwork mod, you can flash the rom directly from your sd card. This also allows you to take full backups, try another rom and if you don't like it you merely restore the rom.
3.Each rom and each dev has their own way of building these roms, so you will need to read carefully regarding what to do wrt sd card partitions etc.
4. Flashing WP7 and the Android rom via magldr would have installed the rom to NAND. You would need to partition your sd card yourself prior to flashing the rom. There are tutorials on how to partition the sd card to give you more help.

1) MAGLDR is nothing but kind of a bootloader. You can select how you want to start your ROM. AD SD or NAND or also now you can back up ROMS with MAGLDR... SD ROMS use haret.exe method. NAND uses DFT.exe method. there is another way called Clockwork MOD which uses .zip method.
Differences:-
SD Method: you have winmo 6.5 on NAND and android on SD card.
NAND Method: you install android on NAND itself.
Clockwork MOD: you install android on NAND but the benefits include you can backup your whole ROM in the actual state and flash it back later... So you can try different ROMs without worrying about installing apps and adjusting settings on the ones you like.
ext4 is a type of partition used by system. you can use the ROM which supports APP2SD and put your apps on ext4 partition.
2) As for the barcode ones. I am not sure how that works, but deffinately not as easy as you are thinking...
3) All the NAND roms use DAF.exe method so you do not need to worry about setting up the ROMs or anything. It does it for you. But some NAND roms have capabilities for APP2SD, in that case you might have to format your SD card in some particular way (explained in the threads always) to get ext2/3/4 partition to use app2sd.
4) you can flash WP7 only on NAND as there is no other way to do it for now. As for the new build you used, it has more than 1 versions. SD and NAND. If you followed the instructions for NAND and used DAF.exe to install it, then the ROM is already set up for you on NAND. Now the build you used had data2sd option and you can format your SD card as the author has said to use app2sd functionality.
One more thing, mostly TMO US users do not need app2sd as they have enough space on their phone. So if you are TMO US user, you can opt your self out from that headache.
Hope this helps. Just for the clarification, I am also a newb... I tried my level best to answer your questions...
QR codes are just text, in this case a URL. Instead of making you type the URL on your phone, you can just scan it with a special app, and get taken to the URL. Nothing more.
Thanks guys...the fog is clearing a little now...just a few reiterations..
So if i opt to flash to NAND, is it flashing it to the NAND upon each boot or is it written once and thats it, it seems to take a little while longer to boot these ROMS on NAND than a stock ROM..so for instance, if i was to remove the SD card after shutting down the phone and then start it up again, would it not boot because its looking for the ROM on the SD to put into NAND ?...i understand that running from the SD card it just boots from the SD card.
So basically the last ROM i installed, as i did not pre setup the partitions on SD card, FAT32/1024mb ext4/512mb ext4 and went on to flash the rom it has ONLY flashed the ROM WITHOUT the apps and everything else it was supposed to have pre installed already ?...so i have now setup my SD card and i am going to follow through again from scratch and hopefully have the ROM running with all the said apps.
My SD card being setup FAT32 / 1024 ext4 / 512 ext4 doesnt seem to be a lot of space to store apps on the ext4 partitions, what data goes on what partitions...and do i HAVE to have the ext 4 at the stated sizes ?
Thanks again guys for your input, you have all been really helpful.

If you use NAND then you can start your phone without SD card. The build is on NAND(ROM). Where win6.5 used to be originally. You do not HAVE TO partition your card. You can use whole card at FAT32 and store all your data on there. But if you choose, you can give some storage space as ext2/3/4 partition and store your apps in that partition. The benefit is you can free some space from your phone. When you boot your phone for the first time, it will be in original state. Then you can install apps from the market. These apps will be going to your phone's inbuilt memory by default. But you can use some apps to move apps from your phone storage to ext4 partition. But be aware that after you move your apps to SD card you have to have SD card in all times or those apps will not work when SD card is not there. As far as the size of ext4 partition is in question, 1024 MB is more than enough. As you will have some space on your phone and 1024MB on ext4. I would say if you install more apps than that, then you phone will be laggy like hell. ext4 partition size should not matter according to me.

^ Agreed. Don't do Apps2SD if you don't really need it. It's another possible source of problems (I've had my fair share of system crashes with A2SD on my ol' Magic, and the biggest problem was that there was no way of backing stuff up - stuff probably got more reliable nowadays though), it's not ideal for your SD card and speed isn't optimal either.

People would have you believe otherwise..ext4 is faster but ext2 parsay is more reliable... for the life of me i have followed numerous guides explaining how to format the card, even one i followed from a rom was in perfect enlgish and easy to follow but my phone just locks at the spinning tmobile logo, it wont even boot into magldr...all i can do is reflash a stock rom using RUU...im sure i am doing everything in correct order
Thread update.
I am now working on providing tutorials for the following.
One card method - I am looking to improve this if I can.
Two card method - This is for micro SD cards over 8gb. There seems to be issues when using 16gb card with the one card method so I am now extensively looking into this to provide tutorial to make larger Android partitions than WP7 if you wanted (As WP7 takes the largest partition with the one card method)
Android SD Magldr Builds - More support and more intuitive tutorials for setting up all known SD Magldr Builds.
I am also looking into alternative ways to the above. I have lots of ideas and theories to improve speed, functionality, setup and configuring you PC/Laptop for convenience to performing the 2 card method, not just for now but for when you do this again in the future. For example, you may wish to install the latest WP7 ROM. The tools are already included in Windows operating systems later than XP. I am now experimenting this and so far, it looks good.
If there are any requests on what else I should provide support or tutorials for, the please feel free to leave you comments either by private message or through this thread.
Please be patient with me as I am trying out the above to make it as clear and hassle free as possible. I have learned a lot from Xda and this is my way of giving back and helping others.

In this thread I have put together a tutorial on how to dual boot WP7 and Android using the one card method. To use Android, the build must be one that has been adapted to work via Magldr. Builds which has been kindly adapted by zarathustrax are on Post 2 so please show your thanks to him for taking time to convert them for us to use.
This tutorial presumes you already know your way around Magldr and know what buttons to press to select etc. If you need any help then let me know. I will help the best I can but cant always promise to be online. The tutorial recommends you use a SD card reader instead of Mass Storage in Magldr as Mass Storage is not always reliable.
1/ Download a WP7 and Android Build (Maglrd Build) you want to use.
2/ Run DWI.exe to install WP7 to your phone.
3/ Go through the setup and once it tells you that you have a new SMS which is welcoming you to WP7 go to Settings - About - Reset Your Phone and once phone restarts hold power to enter into Magldr.
4/ Remove SD card and insert it into the computer.
5/ I used Minitools Partition Wizard which you can get HERE, the Home version is free. Start the program and you will see two partitions on your SD card. Right click and delete the largest partition, this will leave you with Unallocated partition.
6/ Now right click the Unallocated partition and select Create. Leave 'Create As' as Logical and 'File System' as Unformatted. Under 'Size and Location', slide your Unallocated space to the right to roughly half the size of your SD card so the blank grey area is on the left. Click OK.
7/ Now click on Apply (The tick) and when it comes up saying Successful (This may take a while), remove your SD card and put it back into your phone and shut down Partition Manager.
8/ Boot up WP7 and go through the setup again. Once the message beeps again to say welcome to WP7, go to Settings - About and look at the 'Total Storage' and 'Available Storage'. These values should now be roughly the same.
9/ Hold Power button to restart and hold Power to enter into Magldr. Remove SD card and put it back in your card reader. Open Partition Wizard again, right click on the 200MB Other partition and select Delete. Right click on the new Unallocated partition and select Create. The File System should be Fat32 and set as Primary. Click Ok and Apply (The tick).
10/ When all the changes has been applied click OK and right click on the Other partition and select Modify and then Set Partition As Primary. This is important to run Android as well as WP7. If Partition were still Logical then once Android Build was loaded it would not recognise anything off your memory card . Put the SD card back into your phone and boot WP7 and exit Partition Manager.
11/ In WP7, go to Settings - About and double check the Total Storage and Available Storage to see if they are the same as before, they should be except the one should now be 200mb larger.
12/ Power off and insert SD card back into your card reader.
13/ This time start Computer or My Computer depending what version of Windows you are running. Move the Android Magldr folder to your SD card and read the instructions to set boot settings in Magldr. This time I will Boot MarkinXHDExtraClean Magldr Build but DL Desire Magldr build worked for me just as good as Nand. You can also use one of the builds in Post 2.
14/ Once Android folder has been copied, remove the SD card and put it back into your phone. When in Magldr, press the volume buttons up and down until you get to Services - BootSettings - AD SD Dir. For MarkinuXHDExtraClean Build the zImage and initrd.gz are on the main directory of the SD card so select <->. Always read the chefs installation instructions.
15/ You should now be in the main Magldr menu. Press vol buttons and select Boot AD SD.
Congratulations.......you know have WP7 and Android dual booting on your device. If this tutorial helped you, then please hit the Thanks button.
I'm beginning to turn this post into a collection of the builds that I've edited to work with magldr to dualboot with wp7. I am keeping these builds in my dropbox for quick and easy download... just right click the download link and select "save link as". I am just including the entire build for most of these for convenience, because some of the builds needed the init.rc file edited after the build was booted up once, as there were updates and files that get installed on first boot and the init.rc file was changed back to normal... so all the builds here have any updates or files in a root folder already installed, so they are all ready to go... just unrar and copy build folder to root of sd card, and be sure to tell magldr which folder to boot android from. Most builds include a new 1gb data.img or they create one on first boot, in which case it may take 5-10min.
All credit for the builds go to the chefs of each build... all I did was modify the init.rc file so it could be successfully booted with magldr. If any chef does not want me posting a download link of your build here, and would prefer I just post the edited files or not post anything about your build at all, please pm me and I will remove the link immediately. I am not trying to take credit for any of these builds... I am just trying to make it easier for people to install and run.

I'm re-editing some more builds soon, so I will add the rest of the builds I've got running to this post soon.
Very nice tutorial and easy to follow. I had problems before when I tried it and almost gave up.
Thanks
I used the original posted guide to get mine working, albeit I struggled initially due to not reading it properly. If your new guide helps more persons to get WP7 and Android dual booting then that is great BTW I am using this CM7 Gingerbread build on my android partition and it works great, just need to follow the additional instructions in the install folder for getting it to boot via MAGLDR http://forum.xda-developers.com/showthread.php?t=898831

Thanks for your feedback and I have to agree that with the original tutorial, I did struggle with it myself. Also it shows a few ways to do it. The one is a very long process copying one partition to another which dont apply for most people.
I posted this to try and make it clearer and easier to follow. I also focused on using only application for partition management where the original told you to use two.
Thanks for letting us know about the CM7 Gingerbread build. Most builds can be modified in a Linux Distro where just editing one line will make the SD build boot in Magldr.
Thanks so much for the guide and the Android Rom recommendation.
I got a question...
I got Android successfully booted, however under Android environment, it says no SD card is present. I'm using the DL Desire Magldr build.
Do I need to make another partition???
Any help is appreciated
Thanks!
out of curiousity,
Can the both of them share the same set of media files? or do you need two sets of it, one for the android partition, one for the WP7 partition.

Thanks so much for the guide and the Android Rom recommendation.
I got a question...
I got Android successfully booted, however under Android environment, it says no SD card is present. I'm using the DL Desire Magldr build.
Do I need to make another partition???
Any help is appreciated

You forgot to change the wp7 partition from logical to primary. That will solve that.

No, they can't share files. WP7 only reads it's partition and android only reads it's partition.
That's why I like to use dropbox with both of them. I can keep music or files in my dropbox and access them easily from both OS's. There's several dropbox apps for both wp7 and android. It also makes it easy to transfer files to my phone without having to hook it up to the computer or take the card out or deal with zune. Use my referral link below in my signature to get an extra 250mb added to the initial 2gb you get for free when you sign up and install the dropbox app to a computer.

Thanks for taking time to answer the questions in my thread. I normally would have been around to answer them myself except I am doing a very long and painful task of backing up over 150gb off my hard drive before I restore my notebook to factory settings.
You answered them beautifully lol

The answer to the question and the how to is in the tutorial above. I have copied it for you for your convenience.
Make sure you have switched off your phone because you will loose info if you just extract the SD card in WP7, insert SD card into a card reader on your PC. In Partition Manager.....
'Right click on the Other partition and select Modify and then Set Partition As Primary. This is important to run Android as well as WP7. If Partition were still Logical then once Android Build was loaded it would not recognise anything off your memory card.'
Thank you I'll be trying it soon

No problem... I was very active in the other dualboot thread, too. You did a good job writing this tutorial up, so hopefully there won't be too many people confused, but I'll be around to help answer peoples questions, too. I figure once a thread is public, it's up to everyone who knows to help everyone out who's having problems... that's what this community is about... plus the more people that get involved in problem solving, the more we find easier and better ways of doing things. It was actually hyellow and me that figured out that you need to change the partition from logical to primary when I was having the problem of not being able to mount the card in android. It was fun watching and helping the method that you have posted evolve over several days and get easier and quicker to do.
Also, I was thinking that I might collect all my edited SD builds (I've got almost every build working) in to my dropbox and post the links to them in the second post to make it easier for people following this tutorial to grab a build that's already edited to work with magldr. What do you think?
htc hd2 overheats when dual boots
I have dual booted my HD2 using an 8 GB and 16 GB SD card. I got everything up and running and the bottom one third of the HD2 gets hot and freezes or reboots every time . When I placed one rom on the device, the device runs normally. Can anyone advise what might be the problem and the solution.

Can you provide a bit more clarity to your problem.
Does this happen with both the 8gb and 16gb cards? Also what build are you using when your phone gets hot and restarts or freezes?
I find it strange that it is fine when you are using either Android or WP7 without dual boot as you are using only one build at a time when dual booting. You are only gaining access to different partitions on your card, pretty much the same as you would if you have an EXT2/3/4 partition for data saving in Android. Do you still have the same problem if you partition you SD card for a EXT2/3/4 for data saving?
From what you have said the only possible reason is somehow your phone might have a problem dealing with partitions because in theory dual booting runs either one or another and shouldnt be different if you were using only Android or WP7.
Using Minitool's Partition Manager, you might also want to try formatting the Fat32 partition by right clicking on Fat32 partition, click on Format and choosing the cluster size to 32. Save these changes and try again.
The solution could be setting up Android to work properly. In DL Desire's build, there are quite a few options as to how you save your data. You have the save to Data.Img file which must be placed inside the directory for the build, and without going through every type there is also save to EXT2/3/4. You must alter the values in the Config.txt file for the build to know where to save data. Double check you have setup the Config.txt file correctly as you could be telling the build to save to EXT2/3/4 when there is not one. I dont know but it could affect the WP7 partition so it corrupts it and causes the above mentioned problems. Always read the chefs installation notes. Try installing MarkinXHD Extra Clean Magldr Build instead of DL Desire just to make sure.
Can anyone else throw any solutions to this problem?

I completely agree with the community sharing knowledge and that was one of the main reasons for me posting this tutorial. I am a strong believer in if you give a man a fish, then you have provided one dinner but if you teach that man to fish, then he has a lifetime worth of meals.
It would be very generous for you to share the builds you have converted to boot into Magldr as it would give people more options to what build they can choose to dual boot WP7 with. As a matter of fact, being certified in Microsoft, I was looking into doing this myself and was the next mission for me. I have limited Linux use but I am starting to sink my teeth into it and become fluent.
I post a video here if you like to follow by visualization

Hey which would be the best way to do this activate my phone when i get it then flash, or flash and activate the phone service after i install the Os's.

What do you mean by activate? Do you mean get your activation code? If so, get it anytime... you will need the activation code to use live services in wp7 anytime you flash a new wp7 rom. If you mean activate your cell phone service, that can be done at any time, also.

Thank you for the YouTube link to the same process as described in this tutorial.
I have watched the video and it does not mention that you have to change the Unfomatted partition from Logical to Primary. This is essential if you want to use the camera and to gain access to other files such as music from you SD card. Also in the video it is being demonstrated in Easeus Partition Manager. This is a good program but with it you cant change the Unformatted partition from Logical to Primary. This is the main reason I chose to use Minitool Partition Wizard. With this program everything can be done.

Hi installed wp7+Android using dual boot with magldr1.3
now i'm very satisfied with Android, and want to install a new build of wp7 without toutching Android ! how to do? if i install wp i think i will damage android partition in my SD card plz help

That is correct, if you reinstall WPH it will (re)format your SD card and so erase the Android partition.
But some guys here will surely provide the anwser to that problem.

Should be easy, in theory at least.
1. Use a disk imaging software to make an image of the entire partition you use for Android and save that image on your computer.
2. It'll perhaps be a good idea now to delete the Android partition or better yet, delete both WP7 and Android partitions altogether and make just one FAT32 partition spanning the entire card. This might not be necessary but it'll give the next step a stock, empty, Fat32 formatted SD card to begin with.
3. Install the new WP7 build.
4. Go through the entire process of setting up the partitioning for dual-booting the way you did it in the first place with your previous setup.
5. Once you have the Android partition resized and formatted...simply write the disk image saved from step 1 to it using your favorite disk imaging software.
Please note that I have NOT tried this out and can't confirm if it'll work but in theory, it should. Also, if you keep the partitions exactly of the same size that you had in the first place with your original dual-boot setup, it'll *probably* increase the chances of it working in the end.
Hope it helps. =)
I agree with HQRaja.
I would simply create a folder on your Desktop and call it Android Partition Backup, or something simular. Insert the memory card and only the Fat32 partition will be visable in Windows so select everything and move it to the newly created folder on your Desktop. Install Sd Formatter from here. Once launched click on options, Format Type as Full Erase, Format Size Adjustment as On then OK. This will format not only your fat32 partition but remove all partitions as well. Then install the new WP7 Rom, Dual Boot as before and then copy everything from your backup folder back onto your card.
If you feel you dont have enough room for music, apk's or want to try mulitple Android Roms while still using WP7, the keep an eye out for my new tutorial where you can have say over 11gb for Adroid and over 3gb for WP7. It is written out but will read it through more tomorrow to make sure it is ok before uploading. I would do it tonight except my Mrs is nagging and I have been summond .
Hope this helps.
I have been searching for a solution where I can increase/allocate 75% space in sd card for android use and the remaining for w7. I heavily used android because of more games and applications. I am using w7 just for show
Hi,
I intended to post this question to the [3.Nov.2012][ROM] NexusHD2-JellyBean-4.1.2-CM10 V1.2 [NativeSD] thread, but not allowed to (http://forum.xda-developers.com/showpost.php?p=32624318)
Can someone help me redirect the question? Thanks!
First thanks for the great ROM, tytung. It looks great and easy to install.
I have a HD2 and wanted to dual boot WP7 and Android. Found this new method NativeSD and decided to try it. But once I installed the ROM (through MAGLDR 1.13 and Recovery 4Ext 2.2.7), everything works fine, except that the camera app (and other apps) says that it cannot find the external SD card to save the pictures. It does not give me options to save on phone. But since both system and data are on external SD, and that partition is treated as /mnt/sdcard0, I am not sure if I am supposed to have an external SD card from the perspective of Android.
Cannot seem to find similar post with this issue, so I must be doing something wrong with partitioning. Could you help??? Thanks so much! I am inches away from having a great Android JellyBean experience on my HD2.
Thanks!!!
-----------------------------------
Details:
4 partitions on my 16GB SD card:
1) FAT32, 3GB (this is the boot partition, where I installed Recovery 4Ext and through it, installed the boot files in /NativeSD)
2) Ext4, 8GB (this is the system/data partition, where installation put all Android files)
3) Ext4, 2GB (this is current empty, reserved for another ROM that requires two partitions)
4) Other, 2GB (this is a WP7 partition)
I formatted these using Mini Partition Tool on Windows (not via Recovery 4Ext)
I think you need to run CHKDSK on your FAT32 partition of the card with fix option, once, using a card reader and computer. Once done, put the card back to your phone and boot to your preferred Native SD rom. Then check whether you applications are able to trace the SD card. Should work, since the same worked for me, when I had a similar issue. Hope that helps.

Hi dheerajk27, thanks for your quick reply. Was wondering
1) should Android JB think that I have an external SD?
2) where will this external SD be mapped to? The Fat32 partition? The same Ext4 partition as system & data?
3) what would chkdsk do? I just want to make sure that it doesn't mess up the Win 7 stuff as well.
Thanks!
Hi braveliquid, welcome to the forum.
Did you set all your partitions as primary using minitool?
1. yes
2. depends photos/music => fat part, apps=>ext part
3. not sure either

Thanks for your reply. Upon multiple trial and error, I found out that the logical partition is the culprit. When I have 3 primary (FAT32, Ext4, Ext4), Android can recognize the ext SD card. However, when I have 3 primary and 1 logical (the Win Phone 7 partition is made logical by windows), then Android does not recognize the ext SD card anymore.
Any thought on how I can resolve this? Or else I will have to keep 2 SD cards, one for WP7, and one for Android. Doable, but a bit of a hassle.
Thanks!
use minitool and set your wp7 partition as primary too.
Problem solved.
you could use two cards, i am at the moment (I keep spare card in a cellotape pocket on inside of battery cover). You can also dual boot without partitioning see http://forum.xda-developers.com/showpost.php?p=34009754&postcount=1126 but only really as a backup phone in case wp7 goes wrong and you are away from pc.

Thanks Robbie. Yes, I have set the WP7 partition as primary and then it works! I am liking the Android experience (have been using iPhone).
Btw, in WP7, it is asking me to update software (I have a very old WP7 installation, migrated to dual boot in early 2011 i think). Can I just upgrade WP7 like normal (i.e. by connecting to Zune)? Or will that destroy MAGLDR? If that won't work, how can I upgrade WP7 to 7.5 or later 7.8? I cannot use Windows Market Place apparently with the old WP7 OS.
Thanks again!

I would just flash one of the new wp7.8 roms, your choice which. Ansar's does not seem to be able to use the new wpbackup app at the moment.
With Hd2o and pdaimatejam you can backup your phone and restore apps sms calls etc. Sooo much better for trying out new roms.
