Linux from a USB external HDD?

[ALLI]

Not wanting to mess up my Vista setup, I was wondering if I could install a version of Linux onto a USB external drive, and if I could boot to this instead?

Just going to be browsing and folding@home with it so just a bog standard distro. Suggestions??

Have found a Linux I can run off a USB key and either windowed or full screen in Vista. Want the info for that??

I'm actually running the pendrive linux, that was what I was going to suggest.

Can't seem to get it to pick up network settings. Still playing tho.
