Customizing the GRUB Configuration

The grub.cfg file contains most of the GRUB configuration. To add more complex constructs to the GRUB configuration, create a /pool-name/boot/grub/custom.cfg file to contain these customizations. This file shares the same location as the grub.cfg and menu.conf files. GRUB then processes the contents of the custom.cfg file through code at the end of the grub.cfg file.

On a system with 64-bit UEFI firmware, entries in the custom.cfg file might look like the following:

menuentry "Windows (64-bit UEFI)" {
   insmod part_gpt
   insmod fat
   insmod search_fs_uuid
   insmod chain
   search --fs-uuid --no-floppy --set=root cafe-f4ee
   chainloader /efi/Microsoft/Boot/bootmgfw.efi
}

On a system with BIOS firmware, entries might look like the following:

menuentry "Windows" {
   insmod chain
   set root=(hd0,msdos1)
   chainloader --force +1
}
