I have a Gigabyte GA-X99-UD3P mobo and already tried to install the Win7 64 bit but end up (each time) it gets to the point where the OS reboots and then goes black screen and reboots over and over with the Gigabyte splash screen. Now when I checked for updated drivers it says on a few of them to "Note: Windows setup to read from USB thumb drive." That's where it stops for me. And since you CAN NOT talk to ANYONE at Gigabyte, this leaves to search and search.Any help would be greatly appreciated or even a link to a video
