I faced the same situation a few days ago and was able to recover
the machine, possibly because I did not allow it to reboot. Here is
what I did:

- Run regedit (via a networked PC if you cannot run it on the problem PC)
- Change all references in HKLM from F:\ to C:\ (there were only about 15 in
my case)
- HKLM/SYSTEM/MountedDevices/:
   delete all keys which look like "\DosDevice\<DRIVE_LETTER>:"
