I've used TrueCrypt before, but I'm facing some issues.

I currently have a dual boot in my laptop with Windows 7 Professional and BackTrack 4 and only one hard drive. It seems that this isn't very attractive to TrueCrypt, as it doesn't let me encrypt the whole drive with multiple operating systems.

And since I have to be using windows bootloader I tried installing easyBCD but it didn't work, at all with this OS combo =/

Would it be possible to encrypt only Windows partition, stating that I only have one Operating System, and then do the same to linux?

What have you guys done?
