Windows 10: INACCESSIBLE_BOOT_DEVICE after windows 11 update

HiI am running on Windows 11, I had an external drive plugged in when I decided to answer to the prompt to update windows and restart. After restart, I kept getting INACCESSIBLE_BOOT_DEVICE. I tried to restart in safemode or restore to a point before the restart, none of these worked. Thanks for helping

INACCESSIBLE_BOOT_DEVICE after Windows Update


My Windows 10 Pro PC received the latest round of updates, and when it restarted, it bluescreens with the error INACCESSIBLE_BOOT_DEVICE.

I did a system restore to a previous restore point, and everything booted and ran perfectly, but of course it then goes out to get the latest updates, and the same thing happens with it bluescreening and throwing the INACCESSIBLE_BOOT_DEVICE error.

I followed many suggestions from a Google Search including disconnecting all drives other than the boot drive, running chkdsk /f on the boot drive, allowing Windows 10 to "auto-fix startup problems", and several other things, and it always bluescreens.

I temporarily disabled the Windows Update service so it doesn't go out and auto-grab the updates, but at some point, I will need to apply updates, and I expect future updates to result in the same bluescreen error.

Suggestions?

 

Inaccessible_Boot_Device error in Windows 10

Hello,

Thank you for contacting Microsoft Community.

The INACCESSIBLE_BOOT_DEVICE bug check indicates that the Microsoft Windows operating system has lost access to the system partition during startup. The INACCESSIBLE_BOOT_DEVICE bug check frequently occurs because of a boot device failure. During I/O system
initialization, the boot device driver might have failed to initialize the boot device (typically a hard disk). File system initialization might have failed because it did not recognize the data on the boot device. Also, repartitioning the system partition
or installing a new SCSI adapter or disk controller might induce this error.

Suggest you to refer
Bug Check 0x7B: INACCESSIBLE_BOOT_DEVICE and see if it helps you in fixing the issue. Also refer

Troubleshoot blue screen errors in Windows 10. With regard to unlocking the drive, I suggest you to get in touch with device Manufacturer for more help in this issue.

Since you suspect that the problem started after Windows Update. If that is the case, then try to remove that particular Windows Update and see if it makes any difference.

To uninstall an unwanted Windows Update:

• Type “View Installed Updates” in the Search box and then click on View Installed Updates – Control Panel from the Search results.
• To uninstall the unwanted update, select it from the list and then click
  Uninstall.
• If it prompt for confirmation, just confirm the same. Once it complete uninstalling, reboot your PC and see if it makes any difference.

Keep us posted if you require further assistance.

 

INACCESSIBLE_BOOT_DEVICE after windows update

Hi guys!

After latest windows update, I get this blue screen error: INACCESSIBLE_BOOT_DEVICE

After that my laptop restarts and asks for keyboard layout. After choosing US i get Troubleshoot option. I went thorugh Startup Repair, System Restore, Uninstall Updates ... and nothing works.

If i try command sfc /scannow in CMD i get: Windows Resource Protection could not perform the requested operation.

If i try with bootrec /fixmbr I get: The sysem cannot find the path specified.

For DISKPART and list vol I get: There are no volumes.

I also get: total identified windows installations 0 and none of my disks are listed.

Last time when it happened (this is 2nd time after windows update) I needed to disable VMD Controller in BIOS. Now I don't have that option listed.

Windows 11 last version

Aspire A515-56G

Acer

11th Gen Intel(R) Core(TM) i5-1135G7 @ 2.40 GHz

Does anyone know what to do?
