Full disk encryption on dual boot system using TrueCrypt
TrueCrypt doesn't support dual boot systems unless the windows boot loader is used. You can dual boot by using the TrueCrypt boot loader for Windows and chain loading Grub by pressing escape at the password request, I've done this a couple of time with XP and OpenSuSE. You need to install Grub to the boot partition not the MBR. You could then encrypt the Fedora partition.
