In systems where the nvram may have been reset, add
\EFI\BOOT\BOOTx64.EFI to the EFI system partition so that
the image continues to boot. This will be particularly useful
if the NVRAM wasn't written correctly or if the baremetal
server is be simulated on virt and the NVRAM was been reset
on start (as is the case in libvirt).
