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.

    I've just did precise copy of my windows 900GB SSD to new 1000GB HDD with acronis disk director and able to boot once again from new HDD (I've missed my first chance after deleting packages). After boot I've received message  "System restored successfully"

    • don't remember what I did on SSD before cloning (many strange things) . Don't know what to do next, cause I need windows work on SSD.

    TheWizardOfAhhs1 , I have restored already twice the image today on a pc where there the problem reappeared after reboot. I found that in the case of "second reboot halt" there are no items pending for installation. But  what genereates them is the command:

    dism.exe /image:e:\ /cleanup-image /revertpendingactions

    I go much further without running this command. Hope this helps.

     Now they suggest the only option is to reset/ rebuild my PC, but I don't want to lose various software that I no longer have install media and/or keys for.

    Hoping the collective wisdom of the internet may have some more suggestions?

    The command

    dism /online /cleanup-image /restorehealth won't work from preinstallaton environment.

    You need to check on which drive are your Windows files while running from the USB stick. Usually it is D: if you have the system partition.

    Then run dism.exe /image:D:\ /cleanup-image /restorehealth I am writtng this from off the top of my head.

    It is usually possible to see what is broken in the package by examining the dism logs. This is a very tedious work, not worth it if you have another recovery options.

    This didn't work either unfortunately. 

    Am I right in thinking that now my only option is to rebuild and lose all my software?

    If so, my OS and some software are on my SSD, whereas most of my software and files are on my HDD. Can I remove my HDD and then rebuild to protect most of my software or will this not work as all the "my documents" folders etc are on the HDD?

    Happy to try any other suggestions people have, including the registry change (although suggestion above is that it doesnt work)
