Ford, you have some great tut's here!!!! Ok for a week I've been trying to get my 3Tb on GPT I've tried all the GPART stuff, and was able to make GPT partition but now I was able to use Rufus to make USB GPT bootable with my copy of 7x64 It all works great[ boots with UEFI USB LEXAR option] it get thru loading all into Ram BUT when it get to installing win7 just before where you will choose the drive "Starting Windows", the machine suts off, just like you hit the power switch. FWIW, the USB is the ONLY way I can get a UEFI option. I'm stumped??
