I installed windows 7 ultimate from USB using E2B. My board does not have intergrated graphics, nor my CPU. I either run it off AMD FirePro V4900 or FORCE3D HD5770. I booted windows after waiting a long time. Eventually got it installed but it is very slow and some things dont work, the display cuts out after a while and i have o restart the board. It done this to me while trying to boot it. I dont know why
