I have Windows 7 on my PC and the hard disk is divided on three partitions C,E,D. Partition E is encrypted with TrueCrypt. I want to reinstall windows but i have never done this so far when i have encrypted partition on my disk. I will reinstall Windows on C but i want to ask is it possible something to go wrong during the reinstall that could break the encryption on partition E? How do i prepare if something goes wrong to be able to fix it after this?
