Inaccessible boot device after latest insider update this morning (build 21364)

Anonymous

Nothing works in the recovery mode as it cannot back out the update, cannot repair. 

One of the update is kb5003399 and I forgot the other one, will have to boot back to the command prompt.

In the command prompt, I can tell it's not showing my 1TB drive, it's in x:/ with very little space.

Also, wusa.exe doesn't exist in that command prompt. 

Can anyone help to get my system booting again?

    Hello,

    Windows Update install the following driver, Advanced Micro Devices, Inc. - SCSIAdapter - 9.3.0.221, and after rebooting the system enters in GSOD loop with the INACCESIBLE BOOT DEVICE ERROR. The only way to recover the system is booting into Windows Recovery Environment and doing a STARTUP REPAIR. The problem is that Windows Update tries to install the problematic driver again. There is some way to prevent Windows Update to install that problematic driver? Right now I'm using Group policies to prevent the instalation but that also blocks other drivers.

    Also, maybe it's not related, but I think the AMD SCSIadapter is part of the RAID Driver AMD provides for X570 Chipsets. I don't have any kind of RAID configured in my system, so that driver shoudn't be installed. Maybe is a missidentification of NVM Express Controller as a RAID controller?

    I merged your thread into this one because both are basically

    talking about the same thing.

    Please file Feedback and share the FB link here for Eddie (MSFT) to see.

    I made some progress following the step in the last reply of this page: https://social.technet.microsoft.com/Forums/en-US/b228ae18-a637-4887-992f-e3e128e33d74/how-to-fix-inaccessiblebootdevice-windows-10-pro?forum=win10itprogeneral

    The key is to use Windows 10 Installation CD/USB recovery instead of the one from the installed drive. The update messed up that recovery as well so it is not seeing the drive at all.

    I still get the same error (inaccessable boot device) but at least now I can see my drive c: (osdevice) from the recovery command prompt. 

    One odd thing now is that wmic no longer shows the above 2 hotfix is applied.
