Inaccessible Boot Device error in Windows 10

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.

This seemed to work on three different machines - Immediately after removing the package I was able to boot into Windows, but in each case after one restart the system was back to the same BSOD.  I followed the same process again and made sure to disable Windows Updates and clear out the SoftwareDistribution folder before restarting, but it made no difference.

All three of the units required the same package removed "Package_For_RollupFix31bf3856ad364e35~amd64~~/6299.192.1.9" before being able to boot into Windows once.

Edit: I completed full windows reinstall on one of the units and it completed all available updates without issue, no BSOD so far.

I had a very expensive support call with Microsoft and they told me the following:

Acknowledged that the recent security update is broken and they are working to fix it, no timeline on a fix date

Told me the best course is to remove the package, as we have discussed and disable Windows updates. I found the following registry tweak to disable updates from a different site:

Windows Update on a per user basis:

1. Start regedit.exe on the machine where you want to disable Windows Update.
2. Go to HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer.
3. From the Edit menu, select New, DWORD value.
4. Enter a name of NoWindowsUpdate, and press Enter.
5. Double-click NoWindowsUpdate, and set it to 1.
6. Close regedit

What if you have removed the update (on Friday) via DISM, The computer then came back and booted normally.

Computer rebooted to resintall windows update late Friday night while I was out, and now back to the innaccessible boot device message.

The packages are not listed now under the dism commands that i removed before.  There is only one update package listed (from 12/9)   I've run out of patience with this time.

I saw Microsoft released a new patch today

https://support.microsoft.com/en-us/help/4073290/unbootable-state-for-amd-devices-in-windows-10-version-1709

But how can you install the patch when you can't get into the PC?

If it's their bug, they will refund the cost. Ask them for a refund.
