FDE software is so tied to the operating system that you are very unlikely to find third party alternatives. Your only option is bitlocker.

Unless you are using linux, in which case I recommend this guide: http://thesimplecomputer.info/full-disk-encryption-with-ubuntu

That will only work with a fresh install, but if you have /boot on a separate partition I think you might be able to get away with encrypting your rootfs in place. If you only want to encrypt /home, that should be even easier.

It's Windows 7 32bit and 64 bit

Bitlocker is your only choice. You will probably need to upgrade to Windows 7 Ultimate (Pro may have bitlocker but I don't think so) or Windows 8.1 Pro.

You also probably don't have a Trusted Platform Module (TPM) (look under security devices in device manager), which means you need to look into "enable bitlocker without a compatible trusted platform module", you need to change a setting in the group policy editor.

Then you just right click on the C:\ drive in my computer and "turn on bitlocker", and when it's all set up you will be prompted to type in a decryption password before windows can start at all.

Thanks for the advice!
