7050 UEFI Issues (updated)

I image machines with WDS/MDT via PXE boot and USB media.  I have imaged Optiplex 7050's perfectly fine via USB.  I have done Precision 5520's both ways, network and USB.  The problem I am having is when I network image the 7050, once a reboot happens after the image is applied in UEFI mode, the drives are not found.  Switch to Legacy mode and the drive is found, booted to, and then proceeds to finish the deployment tasks. 

I'm sure it is something simple I am missing but not sure what.  Guessing it is a driver issue but it doesn't make any sense seeing as how the boot image is the same on the USB as in WDS.
