I'm trying to install Windows 7 x64 (currently on Windows 8 x64 & got nVidia driver memory leaks, that's why I'm downgrading) but once I enter te UEFI and select my USB device to boot I get a black screen with a white blinking text indicator. And nothing happens it just stays that way until I reboot or unput the USB device.
Thought it could be a USB 3.0 problem but USB 2.0 ports dont work either. I have done manny OS intalls before never had a problem like this...

Maybe someone has a fix for this problem, or I'm missing something stupid..
