Well gee I hate to look a gift horse in the mouth but this one drank the chemical spill water in WV and DIED. The BIOS mod bricked my G73, thanks. Five hours trying EVERYTHING and nothing, It's totally dead. This is FAR from my first time at the rodeo, the last time I bricked a BIOS was at least 20 years ago. This sucks. What the #(&$(#$ macwynn
Make sure 'UEFI Boot' and 'EFI Device First' is enabled when you try this so that the boot menu will detect EFI boot devices. Have You selected EFI Device First as ENABLE an copied into USB Stick the "Bootx64.efi" file ? Because if the Bios get the Bootx64.efi drive it will add into Menu Tabs Bios ! so You can look new drive into bios !!! If answer is yes, You have done it, this means that there is no UEFI yet and we have to try the second firmware with added modules ! Let me know, as to install win8 in UEFI You have to do from USB Stick or DVD and intaller self will ask to format in GPT your HD. I'll wait a reply
