I would not encrypt the whole operating system but use steganography[1] for the most important / delicate files instead. There is a pretty simple to use software called "DeepSound", where you can hide files within audio tracks and even burn them onto CDs, that also really work in a audio CD player. If that is not an option, Veracrypt or headerless LUKS[2] are probably your best bets. If you combine headerless LUKS with steganography, you might achieve full plausible deniability [1]: https://en.wikipedia.org/wiki/Steganography https://en.wikipedia.org/wiki/Steganography [2]: https://unix.stackexchange.com/questions/253493/is-plain-dm-crypt-equal-to-headerless-luks https://unix.stackexchange.com/questions/253493/is-plain-dm-...
