Does anybody have any idea the best way to deploy Windows 7 with on UEFI firmware? I have the unattend.xml file effectively creating the GPT Partition table that is needed however the set up fails subsequetly because the drive is in GPT mode.

I need to identify the EFI windows boot setting which is done with the following apparently

Shell> Fs0: fs0:> \EFI\BOOT\BOOTX64.EFI

Any strategy how we can get a UEFI deployment of Windows 7/2008 R2 working??
