I would suggest using Rufus ( http://rufus.akeo.ie/ ). It should detect your USB drive and you just point it at the ISO. It does format the USB drive though, so back that up before creating the boot disk.
Good Luck
I was going to suggest the same. With Rufus it's as easy as pie. When booting from stick you may have to point the bios explicitly to the stick.
Good Luck
