I purchased a new ASUS G75 loaded with Win 8 and bricked it 2 hours after getting it home. After a lot of trying and reading forums this helped me. http://rog.asus.com/forum/showthread.php?28758-GUIDE-G55-G75-Upgrade-Notes&country=&status=
I do realize that your wife's laptop is probably not the G75 I have and this may not help you as the bios options may be different. BUT, I thought if there was any chance to help you I wanted to do so. I sure hope this helps. It was a real pain in the ass for me to get Windows 7 Pro on mine and make everything work after installing a my SSD into my laptop with the 500gb that came with it.
