Q: Can TrueCrypt encrypt a Windows boot partition?
A: Yes, but not directly. TrueCrypt can on-the-fly encrypt a disk image containing an installed operating system that you run (boot) under virtual machine (or emulation) software, such as Virtual PC, VirtualBox, VMware, QEMU, or Bochs (Bochs, QEMU, and VirtualBox OSE are free and open-source; Virtual PC and some editions of VMware are free).
Tip: That way, you can have Windows installed in a hidden volume.
