It works I had to do it! With 2 drives I had to always boot with f12 to select the Mac drive. No matter what I did as long as I had 2 drives plugged the Mac drive under Boot Drive #1 always showed as UEFI and would never boot twice. It's just not ready for prime time on a Hackintosh.

Thanks for the file.

There should be a "hard drive BBS priorities" option and you have to set the first one as your boot drive to be able to select a non UEFI partition. That might solve the problem you had with the UEFI. I've been using it for at least around a month now and haven't had any problems.

How does your graphics card work? Any edits to the ATI600 Kext? Since I flashed back I have no problems at all. I will wait awhile till all the bugs are worked out.

Thanks again for the info!

No problem. I unplugged my main boot drive as a precaution before installing windows on a separate drive and when I plugged it back in I came across the same problem you were having. Took me awhile to figure it out so I figured I'd put the info out there for anybody else it might happen to.

Graphics card works fine. No kext edits at all. Just a couple kernel flags to get 2 screens working but nothing UEFI related.

I follow this guide to the T, and am ending up with my f10 bios for ga-z68ma-d2h-b3 for uefi. Haven't been able to get into lion since flashing two weeks ago, and I used the lion installer to replace an older time machine, after removing my /extra incompatible files through my windows drive.

I have the lion USB installer, can I install fresh and erase a drive for it? Appreciate any help, I have read hundreds of threads and I am ready to start from fresh, but really don't want to go the snow leopard route.

Thanks :)

Sigh. This did not work for me. It tells me I have a bad BIOS image. I tried two versions from Gigabyte's website that I know I've had on my system before UEFI, and it says both are bad.

I sent a message to their support.
