@dennis-porter FOG does not capture/deploy UEFI boot entries because almost all UEFI firmware out there is able to boot without explicit creation of boot entries and some firmware even has trouble when FOG would so this. So for now I don’t see why we’d add this to FOG.
Though in your case the firmware seems to not be able to find the boot partition and loader and won’t boot from it. In this case you can use Post deploy scripting to add the entry using efibootmgr Linux command included in the FOS inits.
