Encryption should always be accompanied by steganography when dealing with the government if you're concerned about your personal well-being as well. Preferably have an innocent-looking dummy OS that boots up by default.

Does anyone know of a way to boot a different OS based on what BIOS password is entered?

Is anyone concerned about travelling with an encrypted OS - but not a shadow one - and upon decryption, being accused of only decrypting a shadow OS? How would you prove that you're not hiding something?

[JonnieCache]

It is impossible to prove either way.

Which might prove to be a concern when Evil Men With Sticks are standing over you, trying to make sure you're not a spy.

Sounds like traveling with a wiped drive is the safest alternative.

Of course, if the government somehow found out you had done such a thing and you had sworn to help them to your fullest or something, they would not hesitate to slap down a variety of other charges on you. Lying is a serious offense.
