Getting "inaccessible boot device" error after latest Windows 11 update

AMD Ryzen 9 3900X on a Asus Dark Hero VIII ROG Crossfire MB.

I have 64 gb (4x16) G.skill Neo Z RAM.

The primary drive is a Gigabyte Aorus Gen4 M.2 NVME drive in the primary NVME slot (a Gen4 slot).

My CPU and GPU are in a custom waterloop with no leaks.

I have been on this current configuration for almost 2 years now.

I did the latest windows update last night when I was prompted and after it finished I got the BSOD Inaccessable Boot Device error. I am unable to get into windows at all nor can I get into safe mode. I tried resetting my PC and it went through the process but then when it was done I got the same error. After that I updated my UEFI BIOS and it did not help. I did some research online and found most could fix it by disabling VMD in the bios but I have no such setting and all my RAID options are disabled,

I have also tried startup repair and a few other things but nothing seems to work. I've double checked and everything is connected and secure as it should be.

EDIT: I was able to put in a smaller NVME drive and install windows on that. After I got the basics set up I tried doing a repair on the original drive using DISM and it said it completed all repairs but I still get the Inaccessable Boot Device error. Is there a way to fix the original drive from this temporary one so I can boot to the original Gigabyte drive?

EDIT2: Note that when I tried to uninstall the update Windows told me it was not able to uninstall the update. I think it may have not been able to access the drive because the update may have somehow encrypted the drive even though Bitlocker was off and VMD was off.

    Hi,

    I got the same issue on an ASUS Vivobook. After installing Windows 11 24H2 update, I got a "Inaccessible Boot Drive" message at restart.

    After a couples of stop/restart, that update has been automatically uninstalled and everything went back to 23H2 state.

    But this update automatically tried to install again, then I got the same problem again, .. and same solution.

    So I had to postpone all futures updates till Microsoft or Asus provide a solution.

    I too am receiving the error installing 24H2 update. ASUS Vivobook (K3506VU) with an Intel RST. I have disabled and enabled similar settings to the original poster. No such luck, fortunately I am able to rollback the update but … should be able to install this no problem. What’s going on?

    You have failed to say what update.

    Or whether you have run that ssd makers free bootable drive diagnostics

    Or what Disk Management shows fro that drive? Or bios shows what?

    No idea what update. It was done on Thursday night, October 3rd. I do not know how to check what update after it updates and I can no longer boot to the drive.

    Disk Management shows the drive is healthy.

    Someone told me to turn on CSM in the UEFI BIOS and I did, now (even with CSM off) it asks for a Bitlocker key. I was told that Windows has been known to turn on Bitlocker when the user doesn't want it on and locks the drive for boot. I can still access the drive.

    How do I remove the Bitlocker setting on the drive if I can access the drive through my other drive (not booting into that drive).

    Hello,

    Thank you for posting in Microsoft Community forum.

    Based on the description, I understand your question is related to "inaccessible boot device" error.

    The Inaccessible_Boot_Device BSOD error has an error code of 0x7B. This error might occur after some changes are made to the computer, or immediately after you deploy Windows on the computer.

    Any one of the following factors might cause the stop error:

    • Missing, corrupted, or misbehaving filter drivers that are related to the storage stack
    • File system corruption
    • Changes to the storage controller mode or settings in the BIOS
    • Using a different storage controller than the one that was used when Windows was installed
    • Moving the hard disk to a different computer that has a different controller
    • A faulty motherboard or storage controller, or faulty hardware
    • In unusual cases, the failure of the TrustedInstaller service to commit newly installed updates is because of component-based store corruptions
    • Corrupted files in the Boot partition (for example, corruption in the volume that's labeled SYSTEM when you run the diskpart > list vol command)
    • If there's a blank GPT entry before the entry of the Boot partition

    Have a nice day.
