USB drives tend to have firmware in front of what may wish to boot. What I like to do is use Gparted to make room in the end of the drive (say move the end of the drive up so that enstead of having a 16gb fat partition I have a 1 gb fat partition and 15 gb unallocated. I do not bother the front of the drive (other than to add the MBR later in the Linux install).
Then treat the Flash drive as a regular drive otherwise during the install process. Not all flash drives will allow this. Simply find one that does. Currently I am using F20 flash drives to in my laptop and netbook (each specifically made on and for the specific device) to do all of my on line banking. Simply I like the idea of the Flash drive not being exposed to normal use otherwise. I do check the security certificate fingerprints. I do keep the Linux install updated.
