SCCM 2012 R2 OSD Failure in UEFI Mode

I am trying to deploy Windows 7 to Dell Latitude laptop that works just fine in legacy "BIOS" mode (with secure boot disabled and legacy roms enabled). However, When I try to set the BIOS to boot into UEFI (secure boot enabled and legacy roms disabled, the task sequence fails immediately after dropping the WIM down to the laptop.

I have attached the SMSTS log file.

I followed the following information:

Steps to fix this bug:

Edit the Task Sequence.
Locate and select the “Format and Partition Disk (UEFI)” step.
(Preinstall -> New Computer Only -> Format Disk).
Select the Volume: “OSDisk (Primary)”, and click Properties.
Under Advanced options, set the variable to “OSDisk”.

Hope this helps someone else.
