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?

    Same problem here though I'm running at Intel platform.

    What I found helpful is turing on/off PCI Express Native Power Management option in BIOS each time after restarting for installing Insider build. It doesn't matter either on or off all I need to do is turning it. Hope that helps.

    Something else that might be possible is use a setupact.log to see if the errant driver is mentioned and what device it is tied to..

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

    I know..  I was having unexplained drivers put on my system and it was because of hidden devices..  Something is triggering the system to want to install those drivers..  I understand the Intel situation because it happened to me. 

    I know nothing about AMD systems.. but if they may have something related to some type of eSATA controller in the Bios, it may be relevant.  The fact it shows as a specific controller driver does not necessarily mean that exact controller is involved..

    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.
