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?

    Yes. I agree. Somehow the update messed up the recovery image installed as well. That defeated the purpose of having the recovery image to boot to. 

    What worked for me was to use the recovery from the installation CD/USB. However, when trying to remove updates or startup repair, they all still said failed or could not repair but somehow the update is gone after a few reboot. I was trying many things with command prompt as well. One or combination of things I tried worked but not sure which one.

    Thanks Andy, maybe a function which would give a chance to undo any applied update during diagnostic process or save current state automatically before doing any update. This would reduce the cases to reinstall Windows. There are some OEM asking the users for a save before doing any actions. Toni

    ran into the same problem. <salty comments from yesterday after reinstalling windows 4 times> I was finally able to get wushowhide to show the scsi driver by selecting the Dev Channel, rebooting, and then immediately launching wushowhide. So far it seems to work. 🤸 Using the Beta Channel seemed to always force the driver install, but perhaps I'm an idiot.
