I had a laptop that had the whole drive encrypted with Truecrypt, the laptop failed to boot after a month or so, all that would happen is that it booted to the Windows 7 recovery tools. When i tried to restore to an earlier point in time or fix the startup problems, it could not see the drive and the copy of windows to repair.
To solve it I had to un-encrypt the drive using truecrypt recovery disc, then fix boot problems and then re-encrypt the drive. The problem is this took a total of 14 hours to do and some of my users are over 500 miles away and would not be able to do this. Is there a better way of encrypting the systems that will still allow easy repairs to the windows volume if needed?
I encrypted the whole drive but not the recovery area, it is a windows 7 32bit system.
