That section could need info where to set boot parameters in the GRUB configuration of the ISO, which is used for booting via EFI. The next section "Putting the ISO Back Together" is quite outdated by showing only the options for legacy BIOS. A more complete description of the ISO composition step is in https://wiki.debian.org/RepackBootableISO Have a nice day :) Thomas
