UNetbootin allows you to create bootable Live USB drives for Bodhi, Debian, and other Linux distributions without burning a CD. It runs on both Windows and Linux. You can either let UNetbootin download one of the many distributions supported out-of-the-box for you, or supply your own Linux .iso file if you've already downloaded one or your preferred distribution isn't on the list.
