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

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?

    So this happened to me as well.

    AMD 3700X 

    Gigabyte X570 Aorus Elite

    I was able to get back into Windows after 4-5 restarts and my system automatically started diagnosing and fixing the boot failure problem.  It deleted all my BIOS settings, other than that everything seems to be running normally again.  

    Checking Windows Update history it does show the Advanced Micro Devices, Inc. - SCSIAdapter - 9.3.0.221 successfully install on 5/7/2021.  Now I am wondering if its safe to leave this driver installed on my machine.  Furthermore, I cannot see a way to uninstall it if I wanted to.  Its not listed in the Programs and Features list to uninstall.  Does anyone have any advice on that?  Safe to just leave it if my system seems to be fine again?

    Have you tried through Device Manager?

    Have you tried through Device Manager?

    Hello Johnny, I saw that suggestion but when I check for where its supposed to be in Device Manager under Storage Controllers its not there.

    Only entries are:

    Microsoft Storage Spaces Controller

    Standard NVM Express Controller

    Standard NVM Express Controller

    I was thinking maybe it got removed?  But I don't know where to look to confirm that.

    Nothing showing in Task Manager as well. On previous page Eddie MSFT mentioned you should not be offered this driver any more. possibly MS used that new rollback feature on updates, not sure of name and pulled it. Is everything working for you now.
