    So I bought windows 7 and downloaded the iso. I used windows 7 usb/dvd download tool to make my usb bootable with the windows 7 iso. I installed rEFIt. When I restart and select the windows usb icon it loads and I get the error "no bootable device - insert disk..... "

    I have no idea what is wrong ugh! I looked through a lot of threads and nothing is helping.

    Macs are very picky about booting from legacy OSes (read Windows) on USB. Most of the time it will not work even with rEFIt.

    Either burn it to an optical disc and use that, or look for the "without super drive" thread to find instructions on how to do it using VM software or creating a bootable partition on your internal drive.
