Inaccessible Boot Device error in Windows 10

I manage multiple computers running Windows 10 Pro 64-bit with the latest Current Branch and recently had multiple computers randomly startup with this BSOD: Inaccessible Boot Device.

I have tried everything:

https://www.windowscentral.com/how-fix-update-causing-inaccessible-boot-device-error-windows-10

Which recommends deleting registry keys and install packages, though no pending installs could be found

SFC /SCANNOW - No corruption found

CHKDSK /R - Some minor issues corrected

BOOTREC - Scan OS shows 0 windows installations

FIXBOOT - Successful, but this tool finally made the entire process fail without being able to get to the recovery environment, just boots to the legacy screen and shows options for safe mode, but those fail too.

I am at my wits end, because I find thousands of websites and desperate users and admins, but the only fix that works is to clean install. I can't clean install the whole company. This is insane, there has to be a better known cause / fix out there...

WIN 10 BSOD FIX - Inaccessible Boot Device - THIS WORKS!  I Just Repaired 2 computers that went down at the same time last night on 1/16/18

Good Afternoon Bobby,

Here is the fix I came across from another kind IT tech, please see below.  Credits go to them, I'm just forwarding so everyone can finally get their computers back up and running.

Boot Windows 10

Go to Repair

Go to Tools/Options to get a command prompt.

Confirm the drive letter for the Windows image. Usually D: –> dir d:

Run the following to view the installed packages which will also show a date of install.

Dism /Image:D:\ /Get-Packages

Find the package(s) that were just installed by date. Run the following command on the last installed package:

example: dism.exe /image:d:\ /remove-package /packagename:Package_for_KB4014329~31bf3856ad364e35~amd64~~10.0.1.0

Reboot.

The patch that caused my issue was from 1/6/18 or 1/10/18     Remove the latest windows update entry with Rollup Fix in it's name.  Once complete, close command prompt, turn off computer.  Power back up.  You should be back into WIN10.

If you still receive BSOD, rinse and repeat with the next latest update, try it again.  You'll eventually boot right back into WIN10.

I hope this helps.

Have a great day.

    Hi,

    I've mentioned this before, but have you tried downloading a Build 15063 ISO and booting from it to get to the Command Prompt for your BootRec commands ?

    Booting again with RE, starting "regedit" and doing a "load hive" of

    your PC's system registry (C:\Windows\System32\config\system), check

    (in the loaded hive, of course) for any 'suspicious' entries in ...

    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class{4D36E967-E325-11CE-BFC1-08002BE10318}\UpperFilters

    ... this (MULTI_SZ) entry (for class "DiskDrive") should contain (on some "fresh" installation) only "partmgr"

    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class{533c5b84-ec70-11d2-9505-00c04f79deaf}\UpperFilters

    ... this (MULTI_SZ) entry (for class "VolumeSnapshot") should (on some "fresh" installation) be empty

    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class{71a27cdd-812a-11d0-bec7-08002be2092f}\UpperFilters

    ... this (MULTI_SZ) entry (for class "Volume") should (on some "fresh" installation) contain only "volsnap"

    In case your current settings don't contain the above mentioned

    "default/fresh" values, write them down, and change them accordingly.

    Good luck !

    On an older, up-to-date working Windows 10 Pro x32 system with Intel RST RAID 1 that never experienced this BSOD:

    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class{4D36E967-E325-11CE-BFC1-08002BE10318}\UpperFilters

    contains both partmgr and EPMVolFlt

    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class{533c5b84-ec70-11d2-9505-00c04f79deaf}\UpperFilters

    There is no entry for this key, so it is empty by definition.

    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class{71a27cdd-812a-11d0-bec7-08002be2092f}\UpperFilters

    contains both volsnap and EPMVolFlt

    EPMVolFlt is a filter installed with EaseUS Partition Manager and provided by Microsoft.
