    On August 15 I updated from Windows 7 to Windows 8. I didn't encounter any issues during the installation process and there's been no problems with using the system until today, when I decided to update my BIOS to a newer version.
    The motherboard I have is ASrock P67 Pro3. The latest update for it was 3.20, released in June 2012.
    I closed every program before starting to flash bios, but I forgot to run the update as administrator and I had my iPod connected to the PC as it happened. Still, I didn't notice any error messages but as soon as the computer restarted Windows 8 couldn't load. I got a BSOD saying INACCESSIBLE_BOOT_DEVICE. I've tried recovering the system and everything else that the OS allows to do. Nothing's worked. Each time I boot I get the BSOD. What's interesting is that after two BSODs in a row the system automatically lets me pick one of the recovery options and when I launch command prompt I can locate my system drive and all the files on it. In fact, I can even see them in the windows explorer if I choose the option that lets you browse for drivers in the recovery mode. Yet I still can't boot into the system itself. That makes me think something's wrong with the hidden windows partition. I had UEFI enabled when I previously installed Windows 7.
    Is there anything I can do to be able to use my OS?

    I assume you tried and boot from a usb or dvd?
    Flashing bios is a very sensitive task, I wouldn't flash from withing windows or with anything connected to the unit. And this is just for anyone unfamiliar with the procedure...this can brick the system, all caution is needed...
    Anyway, did you try inserting a dvd or usb OS?

    ive tried repair from a installation dvd and cant fix. tried bootrec commands and bootsect commands, chkdsk, safe mode

    this is a macbook pro that had w7 installed and i did an upgrade. the upgrade worked fine, but then on boot it starts booting with the windows square and chasing dot circle, then hangs and bsod.

    the only think i can think of is a driver it is loading when booting that it doesnt like, but no info in the log file to identify. any ideas, seems like safe mode should get me in but it doesnt.

    I got today the problem that my W8 Enterprise was getting problems to boot. Ok, booted from USB Stick to the Windows 8 Setup and chosed Repair. After about 2h all I was getting were a black screen after that startup pics with indicator. So, finally I bboted again from the USB Stick and chosed again to repair. Now I was getting the messages that my HDD were locked and that I would need to unlock. That were just impossible. Booted the machine from 7 Ultimate and tried to access the HDD, impossible. Also used Linux: impossible!

    Did anybody had any idea what could be done to access the HDD?

    Thanks.

    Try fixing MBR via CMD Prompt, that is a shot in the dark but worth a try. Were you dual booting in your machine?
    BOOTREC /FIXMBR
    BOOTREC /FIXBOOT

    Done that already before, with CMD and also with the Toll FixMBR. That didn't work.

    And NO, I did not use dual booting from same HDD! I use the Bios function for chose from which HDD I like to boot. That's the most clean way. Except on my Laptop I didn't use multi partitions.

    May the HDD is dead! It's already 6 years old and I just on installing all again on an new SATA 3 500GB. Just onlky werte need a few files/data. May I can get the out with an Disk Editor.

    Hi,
    Usually when a hard drive is about to die it starts to make clicking mechanical noises which become even more frequently until it, eventually, dies.
    Have you heard those clicking noises?

    I've had exactly the same problem today because I've swapped my motherboard.

    Windows 8 is an abject failure in this regard :(

    In the old days (with windows 7), you could just make sure that the driver was specified in the registry under the "HKLM\SYSTEM\CurrentControlSet\Control\CriticalDeviceDatabase" key.

    Then you would set the service to auto-load at boot by setting its "Start" value to 0

    But now Windows 8 is a horrible mess. The CriticalDeviceDatabase has been deprecated and no longer exists. And now there's a new registry key called "StartOverride" in each service. The complete syntax of that parameter is currently unknown, so some people are experimenting with it and some people just delete the key out of desperation.

    I had to remove the "StartOverride" key of the "storahci" service because I was desperate to get my computer to boot.

    I hate Windows 8!!!

    hi guys, you hijacked this thread with some issue that is not what is described, start a new thread...

    the solution unfortunately to INACCESSIBLE BOOT DEVICE, after an upgrade from w7 on a macbook pro is a full clean install of w8

    Not factually correct. The Thread is: Inaccessible_boot_device in the Windows 8 Forum.

    This is a problem that can have a wide range of causes including drive failure. MS Description:
    Post #5 mentions the MacBook Pro which he upgraded from Win7. This was not the case for the OP.
    How did you interpret this thread to be only about the MacBook Pro and Win7 to Win 8 Upgrade.

    I think it would be better to NOT show Mac/Apple behavior on the forum! This is a forum for ALL Brands and devices.

    Regarding this thread, it's a thread about Inaccessible Boot Device, relatyed to Windows 8 and NOT Windows 7 in first line! If that also applies for Windows 7, we may could discuss about that. To accuse other to Hijack this thread with unrelated content, YOU have to point the finger at first to yourself while bringing Windows 7 AND a Macbook in too!

    So I suggest that you better step back and go to any appropriate Mac/Apple forum before hijacking threads on this forum with unrelated content.

    We talking here about an maqinly Hardware problem an on NON-Mac/Apple, instead of an PC which could running several OS's exclude Apple OS! And we talking about legal OS's and NOT Hackintosh!

    ******************************************

    Hirens Boot CD didn't have the Tools I need for to repair, neither to unlock the drive in Windows 8! After revitalizing, I was able to get that Data out I needed and now the HDD is running on a machine which is "cleaning" the HDD completely. If the 10x Brun In will work without to show any error I could use the HDD again. That will need quite a bit of hours and should be ready tomorrow at noon for to try a reinstallation of Windows 8.

    Still I haven't found any way for to "unlock" the drive after it were get locked. Hopefully this would be a rare occasion and NOT a normal one!

    I bet you're having exactly the same problem as I had. My solution was to remove the "StartOverride" key that is hanging under the "storahci" service.

    I know it's a bit risky to delete things in the registry, but in my case it solved the problem!

    PS: By the way, the "storahci" service is here, in case you didn't already know:

    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\storahci

    thanks, unfortunately i went ahead and backed up my data and started with a fresh format on the partition and install, everything is working great, reinstalling progs now, but i wish i had an opportunity to try this key removal before wiping.

    thanks for the info and i'll file it away for the next upgrade i try on another macbook pro.
