   Is there a place where this process is documented?  I have a computer sitting   
   in   
   that state, BIOS boot and complaining about (U?)EFI.  I'm really hesitant to   
   attack it because of the way the drives are laid out.  Basically there's a boot   
   drive with the OS and the standard files on it, then there are 2 8TB mirrored   
   drives with lots of stuff on them.  While I could backup the data up onto   
   removable drives it's a multi-day process to off-load and then the same to   
   recover it.
