I am trying to install Win8 Pro 64bit. After it starts the installation it says it needs drivers and tbey are nit found. I copied them from the Mobo disk like the manual says, to a USB Stick. Then the message comes up and i browse the stick, select the driver from the list and hit next. The comp starts to load the driver, then the same pop up returns and says it needs drivers. What could make this keep happening?
