First, since 1.99 was released more than a year ago, and grub 2.00 is
now soon to be released, it's odd that you're choosing to use a
release candidate of 1.99 and second you shouldn't use grub-mkimage
directly. You should use grub-install to install grub, specifically
with [U]EFI mount your EFI System Partition to /boot/efi/ then run
"grub-install" (with no other arguments) or if you're not booted via
[U]EFI at the time you're running grub-install, or otherwise don't
want to set [U]EFI variables, use "grub-install --removable".
