Windows 10: Computer No Longer Boots

Don’t know what I did, but when I try to start the computer up, I get this error:
B1InitializeLibrary failed 0xc00000bb

So I made a recovery USB disk, went to command prompt and tried all suggested bcdedit commands out there. All other repair options on the USB don’t work.

In command prompt I can only see two drives, I tried all the other letters of the alphabet:
X: (USB device I’m assuming) and
C: (the UEFI drive)

The original Windows drive completely disappeared apparently.

What do I do to recover that lost partition? It’s difficult to plug this drive into another computer to find the lost partition. What can I do locally at this computer to fix it?

Thanks

:)
