[Q] Noob question: How to boot from SD?

I tried to create a CM7 bootable SD card per the thread entitled "Size-agnostic SD Card image and CM7 installer for SD Cards. with updater."
I used WinImage to create the supposedly bootable SD card with the installer, placed it into my Nook which was fully off, and the Nook booted as usual instead of from the SD card.
Am I missing something? How do you boot from an SD card?
Is there such a thing as a boot choice menu like on my PC or is the default always to boot from the SD card?
Does the Nook have to be rooted for this to work?
Thanks
ETA: My PC shows the uSD card as nearly full, but my Nook shows the SD card as nearly empty (1.74 out of 1.84 GB available).

When you bought your Nook, did it have a blue sticker on the box? And does internal storage show 1GB or 5GB for you?
Also, you did drop an update CM7 zip file onto the imaged uSD before you tried booting off it right?

No blue sticker was on the box. The internal storage shows 5GB.
Yes, I had a CM7 zip file on the imaged card. (The latest encore nightly)
Interestingly, my PC shows the uSD (2 GB) as nearly full. The Nook shows it as nearly empty (1.74 out of 1.84 available).

When you burned the installer img, did you run WinImage as administrator? Also, when you put it in your reader it comes up as boot (drive letter in Windows, with files like uImage, uRamdisk, mlo, u-boot.bin, right?

Yes, I ran WinImage as administrator. And yes, it shows up in Windows explorer as boot and yes those files are there.

Could it be because my Nook operates in "factory mode," in order to skip initial registration?

You should run it and register it and setup wifi and everything first. Get the stock software working fine and dandy (its not half bad actually). Then, checkout this guide for installing CM7 onto an SD card:

It has worked for some rooting rookies so far and includes both windows and mac guides specific to SD cards.

I'm not sure, because I ran through initial registration on stock prior to running CM7 off SD --- I used the same image (verygreen's agnostic at http://forum.xda-developers.com/showthread.php?t=1000957) as you did without a hitch.
If you decide to run CM7 off internal sometime you're going to need to register the nook anyway.
You could try an alternate bootable SD (e.g., using an image from here: http://forum.xda-developers.com/showpost.php?p=13283643&postcount=34) to eliminate one of the two: a) your nook having issues booting from SD or b) your SD install is not set up correctly.

An update: I decided to try to create a bootable SD from another bootable image (MonsterRootPack with CWR). This time the nook wouldn't even turn on. I'm going to try to create a third bootable SD as angomy has suggested to see what happens.
I need to add that when I removed the uSD card, it booted normally.
Also, when I create the bootable SD with winimage, I get a dialog box that tells me that the format of the SD card is not right and asks me if I want to resize the image. But this happened on both the images. I don't know if this has anything to do with it.

Ok, I tried the CWR image in the link you gave. Same problem - no-go. Just sits there dead. I remove the uSD and it boots normally.

FWIW you do not have to boot into stock B&N at all before you setup and install to CM7 SD card. One of my NCs has never ever booted into stock ROM at all, I installed CM7 onto SD card and running off that from the moment it was unboxed.
The NC will always boot off the SD card first, so if it's booting off eMMC instead then there must be something wrong with the img that you wrote to your SD card.
Make sure that you have a freshly formatted SD card, preferably one with good small random block r/w speeds (eg Sandisk class 4 8G). Follow the instructions in verygreen's "Size Agnostic..." OP to the letter. Re-download all the files as you may have a corrupted one. Make sure to check MD5 this time. Try using Win32diskimager instead, the 0.1 version works better.
It should work. Good luck.

Thanks for the link. I have given this some thought, and it doesn't seem reasonable that booting from an SD card should depend upon the state of registration of the device because the whole idea of booting from an SD card means that the content of the SD card is loaded in the place of the stock software.

Thanks. Yes, I just replied to another poster that I didn't think that the state of registration of the device should matter since the whole purpose of a bootable SD card is to load the contents of the SD in place of the stock.
I have followed the instructions in verygreen's thread to the letter - several times. Also, I have tried to make other bootable SDs without success. But that's a good idea about trying Win32diskimager. Also, I will try a Sandisk class 4 card SD as soon as I can get to a store.
I do have a question. When I format the SD card what "allocation unit size" should I be using? (formatting through Windows) The default is 32 kb.

PROBLEM SOLVED!
Thanks to everyone for trying to help me figure this out. The winning idea belongs to robot8.
When I switched from using WinImage to using Win32diskimager, it worked immediately. I am now running CM7 on my Nook Color! Took forever and a day to boot though.

Congrats!
Re: allocation unit size, do you mean cluster size? Depends on how big the FAT32 partition is --- larger clusters used means more actual space used but too large a size can reduce access speed. Generally Windows defaults to suggested 4k for up to 8GB, 8GB-16GB = 8k, 16-32GB = 16k, and 32+ = 32kb.
Also the first boot is the longest --- shouldn't take as long after that. Welcome to CM7 - I don't regret installing it over stock after waffling for weeks on whether or not I'd use stock at some point -- CM7 is just too much faster with too many more options and tweaks for my impatience to deal with stock Froyo.

THANK YOU OP!
I had the same issue, tried 20x various ways, 2 different computers, 2 different SD readers, and it was WinImage that wasnt working correctly. Win32DiskImager solved it.
Thanks.

FWIW, WinImage does not work. Maybe it used to work, but it does not now. I posted about this a few days ago here.

booting from sd - issues with 32gb card

Trying to prepare 32gb card for nook cm7
Using verigreen's size agnostic img
Wrote it to the card using win image writer
dropped cm7 and gapps
on boot it recognizes card, makes partitions, inflats stuff everything looks ok
on reboot it does NOT boot from sd
instead goes to nook default
exact same stuff on 8gb card works fine
what gives?

I have two nooks at this point
both may have cwm recovery - i dont know how to check
(I know how to use nook, update it etc, but not sure about this cwr thingy)
one has cm7.1 on emmc
other has nook 1.2 rom on emmc
in both of them if i insert 8/16/32gb card
1) if sd card has fresh verygreen image with update...zip and gapps..zip installer kicks in and preps sd card
2) once i reboot, it ---- does NOT ---- boot from sd card anymore
All I want is bootable sd card with cm7.1 on it so that I can give it to a friend of mine
what am I doing wrong
is there a way to force nook to boot from sd card?
I think if it finds cwr on emmc and cwr on sd, it boots from emmc or something

I use win32diskimager which I think gives more reliable results.
Also you must mount the card in a PC for writing the image using a real USB / SD adapter. Using a card media slot on the PC or using another device like a phone to mount the card are known to give problems.

Only put the CM7 zip file on it for the first boot.

use easeus partition software to extend the size of the boot partition to 200 MB after you flash the card with verygreens installer, but before you put cm7 and gapps on there.
I bet you it fails to write the kernel during the install because there is insufficient space - try it again without resizing and pay attention to the readout when it scrolls down the screen, you'll see.
cm7.1 + gapps is almost your whole boot partition, for me it leaves only half a megabyte of free space - that's not enough to unpack and install what's needed.

Sorry for the OP but also happy for you that your NC is up and running.
I keep saying many times, do it one at a time.

Sorry to bring this thread back but I'm having the same problem using verygreen's tutorial on my NC 1.3. However after booting the NC I get the "cyanogen mod loading..." screen shortly followed by a blank screen (Nook doesn't turn off, though). If I remove the SD card the nook starts up as it normally would.
Followed the advice of these other members (extended partition size to 16gb/16gb, haven't installed gapps either) but I still can't get it to work.
I'm using the latest nightly release of CM7 following the link on verygreen's tutorial released on 11/23. Should I use a stable version instead?
Thanks...

There's where you made your mistake. The recommendations of the others on the forum were probably to expand the partition created by verygreen's image to something like 200MB or 250MB. The scripts in the image create and format 3 other partitions in addition to the one created by verygreen's image. When you expanded it to the full size of the SD card there was no room to create the additional partitions.
I would suggest you re-apply verygreen's image, expand it to 250MB and try again.

[Q] CWM keeps losing update file

I recently installed CM 7 to emmc after running it from sd for a year. When I first did the emmc install I used mirage 3/4 but when 7.2 was released I decided to try it. Now I want to install the new mirage kang but when I copy the file to my sd card it's not there when CWM looks for it. I wiped data and cache but every time I have CWM look for the file to install it only finds CM 7.2. Any thoughts?
I tried to search but not being able to search for exact phrases makes it hard to find anything.
[edit] When I get home I'll try reinstalling from the eyeballer card I made. Should I format my non-recovery sd card? I didn't need to use the eyeballer card to install 7.2. What's going on here?

Which SD did you put the mirage file on? If you were still using the SD from your SD install, it is not partitioned right to be using with CWM. CWM is expecting just a plain vanilla SD. You may have the mirage file on partition 4 which CWM cannot see.

It was the card from my sd install but I had formatted it when I originally did the emmc install. Also, I used a different card for the emmc install.
What I don't understand is how I updated to 7.2 by putting the file on the sd card and installing it from CWM but when I did the same thing to install the latest Mirage kang it didn't work. I tried toggling the signed requirement in CWM since Mirage isn't signed but it didn't make any difference. Even now that I deleted data and caches and installed Mirage from CWM card the 7.2 file is still on my main sd card and I can't delete it. Do I need to use the CWM card every time I do an update? Could TiBU be causing this?

Do you have your emmc and SD card swapped in CM? You may think you have it on SD but really have it on emmc. And CWM can't see emmc.

No, at least I didn't set it that way. I skipped that part of mr72's guide. Not only that but I tried putting a copy each on my emmc and my sd and it disappeared from the card and wasn't seen on the emmc.
I redid the whole install earlier. I'm going to try putting a Mirage file on the card now and see if CWM sees it.

OP, I've tried to help but really, I can't understand your issue, especially this: "I have CWM look for the file to install it only finds CM 7.2"
What else do you expect it looks for and finds?
Anyway, pls do list as much as info so we can help. I don't want to guess.
1. What is your current system? Is it still running fine?
2. I understand you want to update Cm7. Which version?
3. Since you are running CM7 from eMMC, let just focus on 1 uSD, called "flashable CwM Recovery" uSD. Version 3.2.0.1 is preferred.
4. Do list what else (which files) you have on that uSD. (Using windows)
5. Briefly describe how and what shows on the CwM Recovery window
The more info we gather, the better chance we pinpoint to your problem

update-encore_CM72-MiRaGe-03232012.zip and update-cm-7.2.0-RC1-encore-signed.zip have different file names. When I put the Mirage file on the card CWM doesn't see it. Instead it sees the CM 7.2 RC1 file. That's why I was guessing TiBU, because normally when I flash a file it disappears from the card. I flashed CM 7.2 RC but it won't go away, even if I try to delete it. After conducting the experiment from my previous post I am wondering if my flash card is going bad. I'll do further experiments along that line today.
1. What is your current system? Is it still running fine?
update-encore_CM72-MiRaGe-03232012; occasionally says sd card not installed or available
2. I understand you want to update Cm7. Which version?
I wanted to go to update-encore_CM72-MiRaGe-03232012 which I have now accomplished
3. Since you are running CM7 from eMMC, let just focus on 1 uSD, called "flashable CwM Recovery" uSD. Version 3.2.0.1 is preferred.
yes...
4. Do list what else (which files) you have on that uSD. (Using windows)
I'm not sure I understand what you want here but here's a list of what's on the CWM card: folder (.android secure), folder (Android), folder (DCIM), folder (LOST.DIR),gapps-gb-20110828-signed.zip, mlo, u-boot.bin, uImage, update-encore_CM72-MiRaGe-03232012.zip, update-encore-cwm.emmc-eyeballer.zip, uRamdisk
5. Briefly describe how and what shows on the CwM Recovery window
If you are referring to when I run CWM from this card it installs everything fine.When I wrote this question I was trying to flash the Mirage ROM from recovery and after I selected "install from sd" and "choose which file to install" my only choice was update-cm-7.2.0-RC1-encore-signed.zip rather than the update-encore_CM72-MiRaGe-03232012.zip I expected to see.
Thanks for trying to help. Later today I will try copying my data sd card to another card and see if that fixes the programs saying the card is not available. If it does I will assume the other card is bad. Seem reasonable?

Well, I guess I have my answer. I tried to format my 16 GB data card and it wouldn't format. Looks like card failure. Unless someone has a better idea I'm just going to order another card and chalk this up to running the OS off the card for so long. If flash memory only has a limited number of read/write cycles that must have burned through them.
Thanks votinh, leapinlar. Any other advice, suggestions, ideas on the situation will be appreciated.

Read/write cycle of the flash devices are usually high, 2000+ time, I doubt that you have burnt through.
Anyway, what tool you use to format your uSD?
---------- Post added at 12:04 PM ---------- Previous post was at 12:01 PM ----------
If I was you, b4 purchasing another card, I would try to reformat the card and re-create its flashable CwMR.
If that didn't help, then order new one but note since you only need it for install ROM, 1GB or 2GB is more than enough.

I want at least a 16 GB card for my data and media. I have a 4 GB that I use for CWM and OS testing. I was using the 16 GB card for my OS when I was running off the card. After I installed to emmc I used the 16 GB card for data. The 16 GB is the card that I was having the problem with at the beginning of this thread. Since then I copied everything except my media onto the formatted 4 GB card and everything is running fine. I tried to format the 16 GB card using HPUSBDiskFormat but I got a message "Cannot Format". What program should I be using to format the card?
Other strange things that make me think the 16 GB card was the problem: I recently put some books on the card but they disappeared, one of my apps that is installed on the card keeps disappearing and I have to reinstall it, picture gallery keeps telling me that it can't read the sd, I can't delete files from the card either on the Nook or on my computer.
I hope it isn't the card and you guys know exactly what the deal is but after I put the 4 GB card in place of the 16 GB those problems aren't happening anymore. The final test will be to put an update file on the 4 GB card and boot to recovery. If CWM can see it I can't see how the 16 GB card isn't the problem.

I am aware of this. The fact that it wasn't working like that is the reason I started this thread.
Thanks for your help.

Now, it's a bit clearer that you have both CwM Recovery.
As I always mentioned and recommended NOT to flash CwMR into eMMC as it causes more headache than good but still many others choose to go that way and report more issue. Anyway, let's put that aside.
First step, reformat your 16GB card using MiniTools Wizard. I wish you luck there, if it can't, toss the card but if it's OK then second step, create a flashable CwMR 3.2.0.1 and put just the Mirage ROM in there.
I'm sure you know what to do.
Let us know how things go.

I may have done a dumb thing in installing CWM to the emmc but I was following a guide and didn't want to screw anything up. The reason I put off the emmc install for so long is that fear of bricking my Nook. So far so good on that front.
That tip about MiniTools is very helpful. I was sure there was something better than what I was using but I didn't know what it was. So far I'm getting very strange results when trying to format the card. The program says that the format worked but the files are still on the card. Surface test didn't show any errors. I tried to remove the old partition and create a new one but while that appeared to work there was no change on the card. I do notice that it wants to format the card in NTFS but I was under the impression that it should be FAT 32.
Is the card trashed? I can't think of anything else to try. I even flipped the lock switch and checked it. Still can't delete anything. I can't even delete a picture that I put on there.

As a last hope I tried putting the 16 GB card in my camera to see if the camera could format it. No luck. If the camera can't do anything with it the card is dead. Oh well, at least I got all my data off of it.
Votinh, do you know of any guide to removing CWM from emmc? It wasn't the problem in this case but it's not necessary. I didn't really want it but I thought that's how flashing worked on emmc. I see now that I can use ROM Manager for that.

Honestly, I chose to never flash CwMR into eMMC so I don't have much experience how to remove it, but I'm sure there is way. Will report back if I stumble across any thread about it. NOTE: having CwMR in eMMC is NOT so bad, it just gets you more headache down the road. A lot of people get it installed.
About your card, it's very itchy, ehhhh
Have you actually hit the format button or done or save whatever? and do so with FAT32, not NTFS.
It's first time I've heard the issue.

Yes, unfortunately. I hit format and then the check mark on the far left which I'm pretty sure is save. It certainly said it was doing something and that it had completed the operation successfully. All the files are still on the card though, after 2 formats, one NTFS and one FAT 32, remove and create, and 1 wipe. The files are all still showing on the card and I can't delete any or add any new.

What brand of your 16GB card is it?
I can't imagine that card was extensive damage like that.
Format many times and files still there, amazing.

The card is a Dane Electric from Newegg. I was surprised that it worked as well as it did for running the OS since it's not a SanDisk.

[Q] Unable to root nook colour 1.4.2

Hi
I am new to android stuff, and I am trying to root my nook color 1.4.2 by following
http://forum.xda-developers.com/showthread.php?t=1494901
from above guide i am unable to find how to do a complete wipe for nook color 1.4.2 so I followed
http://www.inspiredgeek.com/2011/05...ware-update-factory-reset-on-your-nook-color/
although its not for 1.4.2, may be to this reason I am unable to do complete wipe nook color 1.4.2.
Also I followed all steps to create a bootable SD card from the 1st source
but unfortunately I am unable to boot nook color from SD card, hence I am not able to root my nook color
Please Help.

usually when this happens there is an issue with the SD card. Reformat it and start again.

Additionally... if you are using an internal SD reader then try buying the cheapest USB reader you can... far too many times this is the issue writing the images to the cards.

That is GMPOWER's ManualNooter thread. If you are running stock 1.4.2, you do not need to do a wipe beforehand. At most, you'd need to do a factory reset via Settings->Device Info->Erase & Deregister Device. If you're running an older firmware version, you can reset using the same procedure.

That describes the "8 failed boot" reset method, which is another way of doing the same thing. If you can get into Settings, you don't need to do this.
Follow the other suggestions for your problem creating a bootable uSD card.

I just bought my Nook Color a couple weeks ago. I had 1.4.2 and I'm using a cheap $6 sd card. Use ManualNooter to root it. All the links for this stuff have already been posted in this thread.
On your computer
- Download and open winimage
- disk > restore virtual hard disk image on physical drive
- flash the clockwork img file to the SD
Use the one for your sd size. I had a 4gb card so I used 4gb_clockwork-3.2.0.1 (there is a list of them)
- Once complete drag and drop Manual Nooter 5.02.19 and Apps2SD Stock Kernal onto the sd
Plug the sd car into your nook and turn it on. Once you get to this point you should be able to follow the directions on the regular manual nooter page. Which is something like.
- Wipe all data, cache, ect.
- Install zip from file - ManualNooter #___
- Install Apps2sd file
- Take out sd card, and reboot
- Done
Then from there you can install other roms the same way you installed the manualnooter zip, or use rom manager

just an FYI... you do not wipe data when using manual nooter... preferred method is wipe... download your content... root with manual nooter

Unable to root
I've read multiple threads on different forums and can't find a solution. I'm trying to root a nook color 1.4.2 and install CM7.
I've tried 2 different micro sd cards, made them bootable with windiskimager, using an external card reader, downloaded the files more than once in case earlier ones were corrupted, no go.
The nook has been reset to factory. It will not boot from the SD card. every time I try it just boots normally.
Any suggestions?
Mine and my wifes nooks were older versions and I had no problems rooting and installing CM7. This one belongs to a friend and I'm about ready to throw it out the window!

Check the device information to make certain it is in fact a Nook Color and not a Nook Tablet... we'll go from there.

It sounds like your using win image wrong. Make sure you have the correct clockwork file. My card is 4gb so I'm using 4gb_clockwork-3.2.0.1 and you load that with winimage. Then you drag and drop the manualnooter and apss 2 sd file.

I'm almost positive that it's a nook color. I did a reset, so I'll have to get my friend to sign back into it to check. I was using a 2gb card with a 1gb image. Most threads state that doesn't matter, but I'll try the 2gb image. After burning the image I was then copying the other necessary files straight to the card.

[GUIDE/TOOLS - NOW OBSOLETE] HDplus CM10/10.1 Easy Install Guide for Legacy SD

UPDATE 05/28/13 - Now that verygreen has changed his SD scheme to his new version, this guide should not be used on his ROMs dated 5/27 or newer. Use his new image and follow his new instructions. If you want to see the old instructions click on the Show Content button below.
Click to expand...
Click to collapse
Many users have had difficulty installing the HD+ CM10/10.1 ROMs using the Original/Legacy (verygreen) SD setup (especially Windows users). I have written this guide and have made some tools that should make it easier. No need for ADB or Linux. I have upgraded the CWM (clockworkmod) recovery to version 6.0.2.8 which includes larger fonts, a brighter screen and the ability to use the internal storage for installing zips and performing backups. It also uses verygreen's process from his early4 zip that aligns partitions at 2M. This guide and tools are for the Original/Legacy SD setup by verygreen, not the Hybrid. If you want the Hybrid, go here.
Setting up the SD
Begin by downloading the files you need either with stock or your PC. You will need my updated SD image file, attached below (do not use the early4 image from the verygreen thread), the CM ROM zip you want to install and the gapps zip to match it. Put the last two zips on your internal media sdcard built into the HD+. You can get the HD+ CM10 ROMs here and the HD+ CM10.1 ROMs here. You can get the gapps zips here, 20121011 for CM10 and 20130301 for CM10.1.
Extract the SD image zip and you will have a 117MB .img file. Burn that to your SD with Win32DiskImager in Windows or the dd command in Linux or OSX. The SD needs to be at least 4GB and preferably a SanDisk Class 4.
To use Win32DiskImager, find it on the web (here, it's free) and install it on your Windows PC. Open it (be sure to run it as administrator) and select the drive (device) that has your card reader with your SD inserted. Then in the image file box put the location where you have the extracted img file. Then when everything is set right, click on the write button. A warning will pop up asking if you want to proceed. When you have verified that you are going to write to the correct device, click on Yes. (One user overwrote their external USB hard drive by not verifying first.) If you get an error message about access denied, it means you are looking at the drive with Windows Explorer. Close Windows Explorer and try again. In fact, it is a good idea to close all unnecessary windows when burning, even your browser.
When burning is complete, insert the SD into the Nook and boot. It should boot to the cyanoboot logo and sit there for a little while while it creates the other partitions on the SD and formats CM10SDCARD. Then it will end up in CWM for HD+ Original SD. If it does not leave the cyanoboot logo within a reasonable time (it hangs sometimes), just touch the power key and CWM should come up. To use CWM, press the volume up/down keys to move the cursor and the n key to select an item. The power key is the back button.
Installing ROMs
You can use the "install zip from SD/choose zip from internal memory" option to flash the CM ROM you downloaded earlier to your internal memory sdcard. Then you can flash the right version of gapps to match your ROM.
When you reboot (you need to leave the SD in the slot), the CM ROM should start. You will need to register with Google to set up Play Store.
If you later want to upgrade your ROM to another build, download it to your CM10SDCARD partition using CM. Then boot to CWM and flash it.
Backing Up
This version of CWM lets you back up and restore your setup. You can even back up to internal memory. It does not back up /boot, but does back up /system, /data and /cache.
Swapping EMMC and SDCARD
Some users have installed CM to a small SD card and want their apps to use the large internal media storage to store their data. I have developed a couple of zips to swap EMMC and SDCARD when booted to CM so that internal memory is available to your apps to store their files. One zip will add the swap and one will remove it. Get them attached below.
These zips can be flashed with CWM but will only install to the Original SD with CM. I just fixed a bug in the rev0 and rev1 zips. If you already flashed rev0 or rev1, you need to flash the remove zip before you flash the rev2 fixed version. No need to boot in between.
With rev2, both SDCARD and EMMC will show internal media storage, as will both MTP folders. A new folder, ext_sdcard, will show the external SD media partition.
Updating earlier versions of CWM
Updating prior installs of the Original SD installation to this new version of CWM is easy. Just download the ramdisk zip file attached below and extract the file. Put your old SD setup in your PC and rename the ramdisk.cwm to ramdisk.cwm.bak. Then copy the new ramdisk.cwm you just extracted to the card, replacing the version that was there. Next time you boot to CWM, the 6.0.2.8 version for HD+ Original SD will be there.

Yes, you can use bokbokan's hybrid image to do it the same way for the HD. And I think his standard image does it too.

question...
Sorry if this has been answered somewhere else but, I did this using a 32gb card and everything I running smooth. I have a 64gb card that I want to switch it out for. I know it won't be a problem doing the root and all of that again, but I was wondering if anybody knows how to change the 32gb SD card back to normal? When I stick it in my computer all it shows is the boot partition and when I try to format it, it only formats that's partition. Meaning that my 32gb card turns into a worthless 116 mb card. I've tried on windows and Ubuntu and get the same results...
So does anybody have any suggestion?

Thank you, I will try that and let you know how it works

This is probably a stupid question, but once I've got the SD card set up properly, can I then go ahead and delete the ZIP files that I've installed? Or do I need to keep them kicking around? Figure if I can free up some space, I should.

You can delete them if you want, but I usually always keep them somewhere so I don't have to redownload them if I need to reflash, which very oftern I have to for various reasons. I can always delete them later if space becomes an issue.

*nod* I meant deleting them off the SD card (should have specified). I'd be keeping them on my fileserver to ensure that I can reflash the sdcard to the same version I started with if I need to.

I'm confused by this, what are you referring to as "internal media sdcard"? I used win32 to burn the .img file, then booted into CWM...I'm clearly doing this wrong, because after that, the sdcard only has 117mb and no room to put ROMs on

You are doing it right. 117MB is what it is supposed to have. You do not put the files on that card. You put them on the HD+ (on the internal sdcard).
If you could see that it only had 117 MB, you were not booted to CWM, you were looking at the SD while it was still inserted in the PC. Booted to CWM means it is in the Nook.
When you insert the burned SD into the powered off HD+, then turn it on, it boots to CWM. That is what I mean by booting to CWM.
The internal sdcard means the storage that is built into the HD+ (that is why I call it internal). Boot to stock and download the files with it. They get put on the internal sdcard or "sdcard" as it is called. After you insert the burned card into the HD+ and boot to it, CWM has the ability to flash the zips by reading them from the internal sdcard built into the HD+.
Edit: I just clarified that in the OP. It is hard to anticipate how users will interpret your words in advance.

You do not extract the cm zip. You extract the image zip which is attached to the post. It is the one that is 120 MB and is the one you burn to the SD with win32diskimager.

thank you for the help. i appreciate it! i can now use my new HD+ (bought it last night) to its full potential.

I just wanted to say that I was suffering from the dreaded "Nook refuses to boot from the SD card" syndrome. I tried three different SD cards burned using four different computers, to no avail. Tried this patch? Worked perfectly. Thanks! :laugh:

SDXC cards viable for this use?
Well, that registration video was a real interesting bit compared to most forums I've ever used. Somebody put a lot of work into that.
I'm noticing a lot of emphasis on Class 4 cards. Impetuous sort that I am, I already obtained a Sandisk Ultra 64 GB microSDXC (Class 10/UHS 1) card for this project. Best Buy had a good deal and I was hoping to have a lot of room to work with and it wasn't clear what access to the internal storage would be available or best left alone. Has anyone had success or great problems with this card?
Other than that issue before attempting to execute the install, this is a very helpful thread. Much clearer than verygreen's original. That shouldn't be taken as an insult to verygreen as technical writing for those outside a project is not a skill everyone has or should have. Asking those deep within a project to shift mental gears to operate at the outsider's level can be a waste of resources and is often better delegated to a specialist. And we should be thankful for those specialists when they volunteer like this.

Some have had good success with that card, especially if they use my Hybrid setup which uses less of the SD to operate from.

It appears to be working on the first try. I'm currently syncing my app set from the Play store. It looks like this will be a huge value add for the Nook. I wouldn't have bought it if the full Android option weren't there. I just hope enough of us still buy books from B&N to keep them going.
Thanks.
