full disk encryption

Hi, is there any way to encrypt whole HDD with triple boot set up? Or maybe just encrypt whole OS X partition will be enough for me, but I didn't found any useful information about it... Thanks.

(Solved) Is Hackintosh full disk encryption actually possible yet? I'm curious if anyone has had any luck implementing any sort of full disk encryption on their Hackintosh partitions (such as FileVault 2, ect..) The Clover bootloader looks promising for such an implementation, but I've not...
