Not sure about the flash drive bit, but I know you can use the alternate cd,
I think, and install Ubuntu on an encrypted partition - at least this
existed in one of the more recent releases so I would suspect it's still in
Hardy. As I recall, grub was not encrypted but shortly after beginning the
boot sequence it asked for a password. I tried it once but didn't really see
a personal need for it. In retrospect, I should probably do this on my
laptop as that is what is most likely to be lost or stolen.

If you are interested in trying, I believe you had to use on of the
alternative install methods under the F4 menu - iirc. Maybe someone else can
confirm or correct.
