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?

    Something everyone might want to check is open the Device Manager and allow it to show hidden devices.  If a device shows as greyed out, it is not currently available.  Look for any devices you know for sure are not available to your system and uninstall those.  I am not referring to such devices and USB external drives and such.

    If you have onboard components you don't use on a system, such as special controllers, you might disable those in the Bios, if possible.  

    And keep in mind, RAID is required if you are running an Intel Optane memory configuration.

    This is specific to the AMD driver mentioned earlier in this thread. It was incorrectly installed on some devices it wasn't intended for.

    Look at your storage controllers. Do you see one that has RAID and Bottom in the title? If so, you are going to want to remove this driver completely from the system.

    There is a newer version (9.3.1.19) on the microsoft catalog,can anyone confirm it to be affected?

    https://www.catalog.update.microsoft.com/Search.aspx?q=AMD+scsiadapter

    I've manually updated to this version across the 3 device types, Bottom Device, Controller, and Config Device, after switching my BIOS to SATA and NVMe RAID, and haven't seen any issues. I only had the issue in this thread when I was running in SATA AHCI mode without NVMe RAID enabled (i.e. the mobo defaults).
