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?

    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

    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.

    Hi I can understand that this can happen. I am also a system engineer in the main frame world. But what difficult to understand is that there are now way to deinstall this driver and make windows bootable again. I tried many options in the Windows Recovery Boot without success. It is really difficult to make an option in the recovery procedure to deinstall single updates ??. This would help to prevent a base install

    my dev work is for linux but I actually don't like linux desktop. I switched from linux to mac about 10 years ago and never looked back. I have not used windows much in my life and only recently started using windows because my macbook pro only has 16GB and I need more memory to compile. The latest wsl2 feature are really nice and that's why I need the insider addition. 

    While I normally use windows with wsl2 (ubuntu 20.04) and vscode, I have a separate drive with full ubuntu 20.04 installed with separate partitions to store the base OS and my project. With windows insider edition, I can mount my ext4 project partition into wsl2. Now I have an OS with full driver support for various hardwares, VPN and can play all the games and do work. Windows 10 with WSL2 is amazing. So, I can live with the occasional update issue by temporarily dual boot into ubuntu and still do my work there.
