When deploying Windows 8.1 x64 with MDT 2013 the computer will reboot after applying the unattended.xml.  After the reboot it does not recognize that an OS is installed on the HD.

I added 8.1 Enterprise N x64 to my operating systems from an unpacked ISO that I downloaded from MSDN.  I created a TS with that image as the OS and changed the disk type to GPT.  I do have Windows ADK 8.1 installed.  I've tried deploying by booting to an x64 based PE wim and an x86.

Also, I'm not sure how this got put in Windows 7 forum anyone know how to change that?

Hi,

Generally,  you would use GPT for UEFI systems, MBR for BIOS-based systems, on UEFI-based systems, it will create four partitions (boot, MSR, recovery, OS) on a GPT disk.

It should just work, as soon as you figure out how to enable UEFI native mode in the firmware (BIOS) settings and then boot in native mode.
