It sounds like your firmware does not support setting of EFI boot
variables. Fully functional firmware should *not* need files in the
removable media path (EFI/boot like that). See
https://wiki.debian.org/UEFI#Force_grub-efi_installation_to_the_removable_media_path
for more information, and the correct way to work around this issue in
your firmware.
