[Need Help] "Missing operating System" - Windows 8 General

Hi all,
I don't know if my problem as already been solved but I didn't found anything.
At first, I have to say I installed windows 8 as principal operating system (I know, it's stupid...).
I used windows 8 without big problem since the deployment but today, after a bug, I reboot the PC and now I have just black screen with the message "operating system missing"... The system does not boot, just black screen with the message
Does anybody have an idea how I can solve this problem ?
(Sorry for my english)

you can put dev preview DVD or USB whatever you used to install.
and run the installation and then repair Windows 8 (if it detects a Windows installed). with system restore or maybe it will repair. if not you will have to refresh your win8.
also it can be (if you have more hard drives) that you aren't starting the one with Windows 8. so you can try and see in bios if thats the case. thats when i have seen this message.

Thanks for your answer.
When I run the pc, it doesn't launch anything, just the black screen. It's probably the bios but I can't do anything, just the message but I'm not allowed to do anything :-(

Finally, the problem is quite solved.
When I have this message, by pushing ctrl+alt+suprr, if I'm enough fast, I can push F12 and choose wich part I want to run. Then I placed my W7 backup on CD and runned it.
It was not easy but W7 is successfull restored.
Of course, all my personal data were deleted...
But whe I reboot the PC, I've always the message "missing operating system", then I have to ctrl+alt+suprr and after F12, and then choose the hard drive, and the PC W7 boot.
It's not yet perfect but for the moment the PC works...

Thats exactly i told you. of course it changes between bios and motherboard. your problem is not your windows. its the priority of your harddrive.
I dont know what motherboard you have.
so i will find pictures to explain what you have to look for. because you didnt have to repair your Windows if thats the case. the problem its (like i mentioned) your harddrive priority.
so you go to your bios and look for the Boot section.
http://www.motherboards-reviews.com...ges/ASUS_M2N68-AM_PLUS_BIOS_boot_settings.jpg
if you go to Boot Device Priority, you can check if your harddrive is second (the one with your OS) and if you want your cd or usb to boot first if not you can leave it first.
http://motherboards-reviews.com/ASU...s/ASUS_M4N78-AM_BIOS_Boot_Device_Priority.jpg
something like this.
and if that part is right you have to go to Hard disk drives
http://www.laptops-battery.co.uk/images/maintain/bios-boot-hard-disk-drives-445x261.jpg
so there you have to check if your harddrive is first or the correct one. and ready... its probably this Hard disk devices thing. and then you don't have to use that method of changing manually which boots

Thanks for your help
I'm not at home for the moment. I'll try your method tomorrow or wednesday, I'll let you know, but thank you for the time you spent on my problem.

vista doesn't boot !

hey guys,
I got an htc shift and when I power it on, it dosent find the vista and says insert boot media in the selected boot device,
I tried to recover it from the recovery partition but it doesn't work either,
I appreciate if anyone can help me.
Have you tried going into the BIOS to see if the HDD/SDD is enabled? If it's not listed, it could be that your drive is dead.
Restart your device (or turn it on if it is off), Press "Del" at the HTC Splash Screen, press "Right", "Return, "Down", "Return". You should see it in the list if it's still working OK. If it is in the list and enabled, check the other Setting under the "Boot" menu and check that it is selected as your primary boot device.
If none of this works (or at least drive is not visible), I think your drive may be dead.
If it does show your Drive in the list(s), but Windows still says there is no boot media, and recovery partition is not recovering it, you'll need to try to install an OS so it has some valid Boot Media to boot from.
indeed I tried the bios setup and my HDD is ok,
I saw some linux an xp bootable images but I am wondering that if I use them my device gona work properly!!
cuz I saw some issues with drivers!!

It's worth a try. If you can at least get it to boot, you may be able to check the drive for errors etc. Don't worry about things working properly for now. Just get the barebones working.
Another suggestion though, you could have a virus in the boot sector. I'm not sure if these are reversible or salvagable, but if you do get it to boot, try running a thorough virus scan to see if that throws anything up.
Failing all that, the best solution for trying to diagnose the problem would probably be something like this...
SSD-to-USB converter
With this, you could connect it to another computer and at least see if the drive is readable. Obviously this means taking your Shift to pieces to get the SSD out, but I've done it and it's not that difficult really.
And your English is good!
sure I'll give it a shot,
thanks a million!

[Q] Disaster - need help...

I got a copy of Android - I think its 1.6 - running on my laptop - and it seemed to work ok and be stable so I wanted to put it onto the machine permanantly.
Trouble is its decided that nothing else on the machine exists and I can't get back into vista whatever I try
It boots into something called grub loader and the only two options are the normal boot and a sort of safe mode - that lists drivers much like the old one for Windows 95/98 where you could y/n each one...
I really need help to get vista back again since there is stuff I really need like internet banking that I don't think I can do any other way (to be fair I have yet to try)
Thanks in advance

Please tell me you partitioned off your hard drive before doing this?
If not then its a reinstall I guess, which isn't to bad as it allows you to install a decent copy of windows such as XP
That quite simply isn't an option - I was told that there is a way of solving it by using a windows CD or boot disk to reload the MBR - I was also told that the file running GRUB can be edited to find windows.
The problem is I don't have another machine and I am on state benefits - I need this computer up and running and I need access to my documents.
I can't seem to mount anything in android - and as the only option is 'format sd card' I don't really want to take it..
Does anyone else have any suggestions?

Well thanks for the sob story but what does being on benefits have to do with anything?
Anyway simply set your pc bios to boot from cd first, insert disk and boot up. From there you will be asked do you want to install or repair. Choose repair.
I'm unsure of the next step because I don't use Vista *spits* but if you can get to recovery console then you can run fixmbr from the prompt and also there is a boot manager that can fix your boot sector.
Alternatively you could from a dos prompt delete the 1.6 folders and rewrite the msconfig to open windows only.
There is also the root of trying the f8 safe mode boot into admin account and rewrite the msconfig from with windows if accessible from f8 safe.
But hell I ain't anyone else but I guess my 24 years in the business of building custom machine and my extensive knowledge of windows xp and below means nowt? Maybe try being a little less dismissive next time hey?
Add me on gmail - [email protected] if you want me to help you sort it out faster than we can here
Did you create partitions before installing android? if not then windows doesnt exist anymore, which is why grub didnt automatically add it to the list of things to boot (mine always listed everything, but sometimes it doesnt do that automatically)
this happend to me to. I had to use I linux live cd to delete the linux partition. and fix the mbr.

[Q] Window 8 wont boot up!!

Help would be great. I have a dell inspiron laptop (not sure exactly what model it is) and I made the mistake of downloading windows 8 consumer preview when it first came out and installing it directly on the laptop rather than dualboot or usb stick. It worked fine for a couple of days and then out of nowhere it wouldn't boot up. When I press the power button the screen will light up and the w8 logo will appear but it won't go past that part. Sometimes It will say auto repairing itself but I've left it on for two days to see if it would fix itself but It didn't. Is there a way to get in safe mode to atleast re install the iso file? I've been without a laptop for a couple of months already and can't afford to buy a new one!

so am I correct in thinking you have no installation media at all for windows? any version?
If so do you have access to another PC because to be honest, your probably going to need it
I assume you have tried hitting F8 on boot to get to the boot menu and that didn't work either?
in terms of your hardware its cool, that's not the issue, the software is, having an install disk would have made things a lot easier....
Yes I have access to another pc and no I don't have any available. I downloaded a newer version of the win8 in ISO format and put it on a dvd disc and tried installing it through the f12 key right when you boot up. The disc drive started running but nothing happened afterwards. Windows recently released a new version of win8. Should I download that one and try it again the same way I tried the first time?

ok, you hit F12 to get in to the boot menu is that correct? then you selected the DVD drive and it made some noises but did nothing?
Ok, Boot menus can be troublesome
What I suggest is go in to the BIOS and change the boot order to DVD first THEN HDD, if that doesn't work then take the HDD out of the boot order altogether, you will need to turn it back on again though to complete the setup
also, I want you to see if the DVD boots on another computer, the first ISO I downloaded was corrupted and whilst mine booted it would always fail to install, re downloaded it and no problems at all
Its probably worth downloading the RP ISO anyway, the previous version the CP, was mass tested in the open market so any issues with installing wouldn't have been worked out in the CP, hopefully the RP would have got most of them,
Hi, i did what you recommended and it worked fine until the install process! It took me to the install screen and i pressed install. Afterwards it gave me the option of automatically doing the install or choosing custom options only. I choose the automatic and it told me that i had to remove the disc and restart the computer and re inster the disc for it to continue! The problem is that everytime i do that it wants to boot up the original way where it wouldnt work! Any ideas. Should i choose the custom option instead ( but i dont know what to choose if i do it that way)??!! Thanks for your help

HI!
Yes, you are right.
Boot to the install media, at the option to do custom, select custom.
When the screen loads showing the partitions (drives)
-Click advanced on the bottom right
-highlight each partition and delete them (this will loose all data saved there but unless you have a boot disk or usb or remove the drive from the laptop, the data is usless anyway)
At this point you can click continue, or next Windows setup will auto create the partitions it needs and unpack the files, then finish install.
If you get any issues with files missing or media is corrupt from the ISO, you will need to down load it again, use the MS download manager or some manager to ensure the download is good and the file CRC matches what they have on the download site. I have seen this a lot lately so don't waste your time restarting the install if it has an error while coping files, just get a new download.
I hope this Helps.

This does resemble a copy error, or even a hard disk/hard disk controller problem.
I have a desktop computer that will no longer boot up from any IDE devices (even if their properly formatted, it also includes any optical medium), Trying to boot from them results in a "DISK NOT BOOTABLE" (something around that, Acer's boot errors are different from the usual ones.
Anyway, back on track, before all that happened, I had trouble booting the computer from the IDE HDDs, sometimes it would boot and sometimes it stuck at the Windows 7 loading screen till it said a file was corrupt or missing, or it BSOD'd.
I also recommend re-downloading and trying the install again, in extreme cases, if you have another HDD to test, try installing it on a different HDD. If that works, the problem could be your hard disk (or something more nefarious, who knows ^_^

Windows 8 won't start

First off i apologize if this is the wrong place to ask this, i couldnt find a Q&A thread for windows, also ive spent hours on Google looking and couldn't find anything that worked, but anyway my aunt a few days ago hit her computer( shes the kind of person where if it doesn't work just hit it) and it black screended on startup, like you press the power button and nothing, its a lenovo (i dont know what model) but i booted it into recovery, did a BIOS recovery, but it didnt finish, so i checked to see if the computer was reading the hard drive and it is, im taking my Toshiba to swap the hard drive to see if thats the problem, she wants to keep all her data but i said that may not be a possibility, i just want to know if anyone here can tell me what might be the problem, im convinced its thr hard drive as the toshiba had a similiar fate a few months ago. So any help would be great, also again if this is the wrong thread im sorry
EDIT: I don't know if its Windows 7 or 8, also its current state is it stops at the lenovo boot screen

Try windows start up repair. easiest way to do this, get the windows installation disc and boot into that and select start up repair.
id guess a HDD failure or more likely a corruption with windows if it wasnt shut down properly
could also try a fresh install of windows, just dont format the harddrive during installation. this way windows installation should save all the old data into a (old windows) folder on the c drive

Before buying a new drive, put her hdd on your pc to see if it is still healthy, bad-sector-free. You check this with hdsentinel.
Also, try to boot her laptop with a hdd/ssd that is working properly.

I tried looking for a hard drive adapter, i didnt want to put the hdd into my computer as i read it could crash it as the drivers are for a different computer, but if it works without harm ill do it, also finding an adapter here isnt easy, as i live in mexico and BestBuy is 2 hours away

Hm, I don't think that plugging the hdd will crash your computer, but still, it's just a crash, unplug-restart and it's gone.
However, since I haven't been in a similar situation, you can try to plug it in a computer that runs any OS but windows, e.g. a linux pc, since win drivers won't affect a different OS.
Yet, I think it's obvious that if you plug it in your pc, you won't select it as a boot drive.

Backup any data that you don't want to lose and store it somewhere other than on your laptop's internal storage. Then download the hardware drivers(including any BIOS updates) for your specific laptop and the drivers for any other external hardware that you use with the laptop. Then do a complete format and reinstallation of Windows 10 using a Windows 10 .iso. Then reinstall your laptop's hardware drivers, starting with your chipset drivers, then video and audio drivers, then the rest of your laptop's various hardware drivers, then drivers for any external hardware that you use with the laptop.
Then you can copy your backed up data back to your laptop.
If you reinstall the system, you need to enter the license key. Even if you rolled back or transferred Windows to a new laptop, you still have to enter the key. When I bought a new PC I had to completely transfer the system to the new PC and consequently change 7 to 10 windows. I re-downloaded drivers, all necessary applications, installer packages. But then it wouldn't start because the system failed. My laptop has a new boot system that has been changed and it was not possible to just run windup from a flash drive. I bought the windows 10 pro key separately and entered it to activate all the packages. Everything worked.
