This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.

    
Have you enabled booting from USB in your bios? How did you "burn" the image to a usb? –  Ankur Aug 11 '12 at 0:22

It depends on what you're trying to boot. If you're trying to boot something that's Linux, UNetBootin is great. For Windows 7, give the official Windows 7 USB/DVD download tool a whirl.

As the question sawdust linked explains, you will need some kind of boot loader for images 'burned' to a USB drive. Both these utilities will take care of that. (Anyone know of a solution for pre-Vista installs?)
