Some computers can boot from USB devices. It all depends it the BIOS allows it. Just go into the bios when you boot, go to your boot devices, and is USB device is listed, select it. I wouldn't suggest running your OS off of any USB device though, since USB is alot slower than IDE, SATA, or any other internal connection.
