EFI: Boot option on Win7 64 install not available

[johanbar]

Hi Guys

Hope someone can assist:

I'm trying to install Win7 64 to a existing GPT disk on my GA-X79-UP4(rev. 1.0) Bios Ver : 2 board.

I have ACHI enable on all the SATA connectors and have a LG bluray drive connected up with my install DVD which works just fine.

It boots the Bios version of the Installed but I cannot get the UFI:Boot version available or see it in the Bios.

Is there a reason why the board wont allow or display the EFI boot option?

Thanks
Johan

Hi Guys

No replies   Its clear now that the board does not pick up that the Install DVD is EFI bootable.  I created a USB install stick with the Microsoft USB DVD download tool.  Only now does the board detect a UEFI: USB boot drive.

Finally I thought: I booted it. Try to install to my GPT drive and it says "You cannot install to a GPT drive"  I hit Shift F10 and load \Windows\Panther\setupact.log from the setup media:  and there it is: Callback_BootEnvironmentDetect: Detected boot environment: BIOS

Its still in BIOS boot.  How do you boot this thing in EFI ??

I should have bought Asus

Hi there

It seems this is an issue with a copied install disc. Even from the original .iso available from Microsoft, the board does not detect the EFI option for boot media.

I proceeded to make a USB Win64 boot stick - now the EFI option is available. When you boot this - it still boots to Bios and not EFI. (very poor)

I then used this post http://forums.bit-tech.net/showthread.php?t=209045 to force a EFI boot. This works. Only to run into other issues.
