I meanwhile wrote to you partly on bug-xorr...@gnu.org and partly in a reply to your private mail that step 2 is unnecessary and also uses an unsuitable mix of options and ISOLINUX MBR for exposing GRUB equipment to the boot firmware. In the replay to your private mail i proposed to omit step 2 and to hand over your directory "out-combine" to the grub-mkrescue run of step 1: grub-mkrescue --modules ="part_msdos, part_gpt, gzio, ext2, iso9660" \ -o final.iso -d img0 out-combine At boot time it will turn out whether your prepared GRUB configuration in "out-combine" will do what you desire. If it does not, then you should look for advise about how to properly prepare "out-combine". (Here ends my expertise as far as boot preparation is concerned.) Have a nice day :) Thomas
