-To install with EFI:
-
-A: install grub-efi
-
-apt install grub-efi
-
-B: Add to the installation process in scripts/package-iso
-
-1. Make directories ${CD}/boot/grub and ${CD}/EFI/BOOT
-2. Install the various grub modules from /usr/lib/grub/x86_64-efi/ to ${CD}/boot/grub/x86_64-efi/
-3. Copy scripts/grub.cfg to ${CD}/boot/grub/grub.cfg
-4. Run grub-mkimage to create the grub image: 
-
-(cd ${CD} && grub-mkimage  -O x86_64-efi -o EFI/BOOT/BOOTX64.EFI --config=boot/grub/grub.cfg --compression=auto --prefix='()/boot/grub' disk part_msdos fat iso9660 )
-
-NOTE: do *NOT* try to install the linux module directly in the grub image; it causes command-line options not to be passed and is a known bug.
-
-5. Add the following xorriso options
-
-    -eltorito-alt-boot -e EFI/BOOT/BOOTX64.EFI -no-emul-boot \
-    -isohybrid-gpt-basdat \
-
-This installation includes *no* additional icons or drivers. It is just meant to get RancherOS booted on an EFI system.
-If you want to add support for graphical installations, additional filesystems, and everything else.... you will need a lot more
