I myself wouldn't recommend a dual boot.. I prefer live CDs and live USB, especially live USB. That way, it keeps everything off of your computer itself, and you can easily use someone elses computer if need be. So if someone were to confiscate your computer or laptop, nothing incriminating will be on there (assuming you've used it for illegal activities in this situation), it will all be on the flash drive or CD. And even then, they'll only find the OS.
