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:

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...

*Modified title for accuracy*

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~~

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.
