Gigabyte GA-Z68X-UD3P-B3 failing to install Windows.π

[lovelyzoo]

I'm trying to install Windows7-64 on to my machine. My spec is:
Intel i5 2500K - Gigabyte GA-Z68X-UD3P-B3 F4 - 2x Corsair Vengeance 4GB CMZ4GX3M1A1600C9B - Gainward GeForce GTX 460 GS 1024MB

I have a 1TB Seagate Barracuda attached to the SATA3_0 port.
The drive was GPT formatted with four partitions using Apple's Disk utility.
Subsequently, I reformatted my Windows partition as NTFS using Ubuntu's Disk Utility.

EFI CD/DVD Boot Option is set to EFI.
SATA ports are operating in AHCI mode.

When I try to install Windows I get the following error message:
"This computer's hardware may not support booting to this disk. Ensure that the disk's controller is enabled in the computer's BIOS menu."
What am I doing wrong here?

Hi and welcome.

I think it is probably that you haven't used Windows formatting tools.

Thanks, but now that I think about it, I also tried formatting the partition in the Windows Installer and that didn't help. Also, I've examined thepartitions on the drive and there is an EFI System Partition at the beginning and a Microsoft Reserved Partition immediately prior to my proposed Windows system partition. As far as I can see I should be good to go.

OK, ignore this. I've decided to go for an MBR table to sort this out.
