The lines, which will need changes for using GRUB, are at least:

-b isolinux/isolinux.bin
grub-mkrescue (on Debian) uses instead:
--grub2-mbr /usr/lib/grub/i386-pc/boot_hybrid.img
-b boot/grub/i386-pc/eltorito.img
-no-emul-boot -boot-load-size 4 -boot-info-table --grub2-boot-info
Is there a possibility of dropping MBR? i.e. use GPT containing both a
biosboot partition type, and EFI System partition type?
The advantage of this is not just to get rid of MBR really. But if
there are still some systems out there that will face plant on GPT
anyway, it's probably best if they face plant when booting the
installation media rather than getting all the way to a successful
installation, just to face plant upon reboot.
