This may not be the most appropriate place to post this, and if so, my apologies in advance.

Here's what I'm looking to do. I want to have BT5R1 installed as a hidden OS on a fully encrypted 64GB SSD USB drive with pre-boot authentication. I can't seem to find a comprehensive encryption solution. Trucrypt supports system encryption and hidden OS's, but not for Linux. The other encryption applications I've investigated either don't support system encryption, don't implement hidden OS support, or don't support Linux. I've gone through the wikipedia of encrypted software as well as many hours spent on Google. Either I missed something or what I'm looking for doesn't exist/isn't possible.

Thoughts? Suggestions? Guidance?

Thank you all in advance!
