I'm trying to modify them as follows : isolinux/menu.cfg
LABEL English (en) SAY "Booting English (en)..." linux /live/vmlinuz boot=casper APPEND file=/cdrom/preseed/preseed.cfg auto=true initrd=/live/initrd.gz boot=live components locales=en_US.UTF-8 quiet splash intel_iommu=on boot/grub/grub.cfg menuentry "English (en)" { linux /live/vmlinuz boot=casper APPEND file=/cdrom/preseed/preseed.cfg auto=true initrd=/live/initrd.gz boot=live components locales=en_US.UTF-8 quiet splash intel_iommu=on "${loopback}" initrd /live/initrd.gz } I'm not even sure that it's correct,mostly because the grub.cfg file uses two command lines. The second one is "initrd /live/initrd.gz". I'm not sure if it should be there or if I should delete it.
