@rayne Well this isn’t getting us to a solution then. The issue is between the uefi firmware and iPXE. If your firmware is up to date on this system (please check), then we will probably need to create a usb boot disk to load into FOG imaging. You will lose some capabilities that iPXE has but you can unicast image with this route.
First check the firmware then if that is up to date I can give you guidance on how to create a FOG usb boot drive.
