XP deploy task sequence on UEFI failing

I'm having a challenge with my prestage step in my task sequences.

I'm using a similar format partition to that being used by my win 8 task sequence that is properly deploying but the XP version is failing to prestage content.

I'm starting from a diskpart clean before booting onto usb drive to execute sequence and it is creating a single partition instead of the uefi version before prestaging and doing the initial reboot before starting. The format/partition steps all match the win 8 sequence and that one works fine. Ideas?
