Installing Windows from a Thumb Drive

I have an Aluminum MacBook, is it possible to install Windows with boot camp from a thumb drive? I have access to the ISOs I need (from MSDNAA), but I ran out of CDR/DVDRs. Ideally I would extract the ISO onto the thumb drive and have it behave the same as if it was a CD, is it that simple or is there something else I will need to do?
