There's also an unsupported, may go away in the future gptboot.efi that you can use if you really must use this setup.. We use it for bootable USB drives at work, but if it doesn't work for you, I'm not sure I'd fix bugs in it. However, we're moving to ZFS only, and we've found ZFS BEs to be way more flexible and will be the way of the future. As such, I've stopped maintaining gptboot.efi and will likely remove it in the future.
