The command to use is chainloader or similar (as opposed to the 'linux' command used to load a Linux kernel) and it takes the name of other .efi image as the parameter. You can try it in the grub commandline. If you want to put that in a menu look at the existing config and the scripts in your distro that generate it. Editing the config file is generally useless as it is usually generated by a script. > > > > > > > > > ??????????????????

I think it was in old BIOS times. EFI was a boot order concept, in one > loader is failed, another one is trying to boot. If the boot loader exited it has obviously not loaded any OS hence it has failed.
