Yes, reboot, then repartition the Hard Disk to GPT.
As long as you boot into WinPE on the next round in UEFI mode, MDT LiteTouch and SCCM OSD will handle the rest, including cleaning the disk for GPT for New Computer scenarios.

I want to change this to UEFI with SecureBoot when we deploy Windows 10. During the task sequence, if I use Dell's tool to change BIOS to UEFI and enable SecureBoot, do I need to reboot before I install Windows? Thank you, Daniel
