First of all, this usually isn't recommended, but if you are sure that you want to, go ahead.

Do you plan on keeping the files and settings that you have? If so, you need to follow a procedure like this (http://linuxologist.com/1-general/howto-fresh-ubuntu-install-without-losing-your-current-settings/). To boot from the USB, plug it in, and then boot into the Bios. When you are in the Bios, look around for "boot order" or "boot sequence" and when you find it, set the USB drive to boot first. It would probably be named something like "USB Drive" or the name of the manufacturer.
