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?

    Me as well, tonight (7/5/2021).

    Similar hardware to OP, no SCSI devices. But I am not on the Insider program. This is being rolled out mainstream now. And it is not an optional driver update: it appears as a 'reboot to complete installation' notification.

    As above, Windows automatically removed it and blocked it after two failed boot attempts.

    I have the same problem on my Aorus 570 Ultra (with MP 600 SSD) and it kept me up for hours. The problem is that my configuration probably has hundreds of users in Germany, because the largest PC magazine (c't) recommended this PC configuration in 2019 ... Please solve the problem ...
