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.

    Let's get back to the main issue at hand.  What is the resolution to the BSOD issue?  Why are we dealing with this?  Get a hot fix sent out and lets be done with it.  Mean while I've moved on...  Point is, make sure you back up your data, or just do a fresh reinstall because it's always going to FAIL when a Microsoft Package_For_RollupFix31bf3856ad364e35~amd64~~16299.192.1.9 windows update comes out.  Thank you Microsoft for the support.

    What Susan is talking about is called an In Place Update.

    The important thing to remember is it is runs on a running, working Windows  PC, everything yours is not doing. It will run in it's own WinPE and do a full UPGRADE. You will loose your installs and data ON THE OS DRIVE ONLY.

    That is why I didn't suggest that way, otherwise known as a Clean Install.

    If you noodle around in WinPE and on your other PC for doc, you may find away to rebuild your Registry/Config??????

    Or loose everything on the OS partition.....

    Best Regards,

    Do you have another computer that you can work with and use?  If I were in your shoes I'd download Windows 10 media and get into that and see if you can use the recovery window and then do a method to reset your pc.  https://support.microsoft.com/en-us/help/12415/windows-10-recovery-options  This will reinstall the OS but won't damage your files.

    https://www.microsoft.com/en-us/software-download/windows10 Go to the media tool download section and build a recovery iso.

    I do have another windows 10 PC (laptop)  I'll take a look at this now.  Thank for the reply! I really appreciate all the help.  What a mess! :)
