Last week I put together a ASUS Z9PE-D8 WS that I got in May. Everything worked and the system booted on the first try. I could not install Windows 7 x64 in UEFI mode. After a couple of hours I did a legacy install. How do you use the UEFI mode on this motherboard? I tried the manual and a Google and Youtube search and did not find anything. I made a UEFI usb for the install but I am not sure if it works. Is there a way to test the USB stick? This is my first board with UEFI bios on it so its all new to me.

Also, why is there a big gap between where the post starts and the text?
