@wmw509 Give the steps outlined by George a try but I can imagine this being caused by some fancy logic within the UEFI firmware. As George said FOG is not at all touching any firmware or boot settings… unless you have added post deploy scripts doing something special.
Here is another test: Schedule the deploy task as debug. When you get to the shell run efibootmgr command (don’t know if you need parameters or not from the top of my head) and take a picture of the output in screen. Now start the task with command fog and step through it. At the end run efibootmgr again, take a picture and compare/post here. Before you type reboot schedule another debug task for this machine and see if it PXE boots into it.
