Fixing it isn't hard and it could probably be automated with WinPE, but the real problem is BitLocker. This makes the process tedious since you can't automate it totally and you also need the key which might require a login on microsoft's site and then writing it by hand or finding the stick that had the key. I was reading that sysadmins on reddit were complaining that they lost the passwords to the microsoft accounts so they are doomed.
