Hi all, I'm having a few problems with a new Sandybridge systems i'm putting together at the moment, mainly related to the hard drive and what seems a lack of UEFI boot support from the EFI BIOS. So far i've tried just about every google result to get windows 7 x64 to install in EFI mode with a full 3TB available but it simply will not work.

It seems Windows setup also boots in BIOS mode and thus will only install with the older MBR type limiting me to ~2TB. The EFI BIOS has no options to force BIOS or UEFI booting like i've seen in a few screenshots.

The board is set to AHCI mode on the SATA ports and i've tried both the Intel 6GB/s ports and the Marvell ports the board also has, none work. Juniper Srx Firefly Download. If i manually force the drive into a GPT mode with a 2.8TB partition then Windows setup says it cannot install to a GPT drive.

On following advice online i tried making a UEFI only Windows 7 DVD to force a UEFI boot, but the board will not boot this disk at all, leading me to believe there is no UEFI boot support what so ever. I've also tried updating the motherboard to the most recent BIOS image - no change. Does anyone have any ideas or know a setting i'm missing somewhere, or is this a motherboard/EFI issue?

Cheers for any help! I would think you would need to boot into EFI of the DVD. If you press F8 before BIOS posts* it should give you a boot selection. Choose the one that has UEFI before your DVD drive with the Windows installation disk. I've never tried installing Windows to a GPT but hopefully there should be some options to format the hard drive to GPT.

You might need to delete any MBR partitions (which I think you should be able to do in the Windows Setup) so as to present a clean disk but I'm not sure. See how it goes. *Alternatively you could go into the BIOS - Advanced - Boot and select the boot override as UEFI: CDRom?
