Re: Some of the parameters used in my genisoimage command don't produce a bootable ISO image

What is "${loopback}" in the context below ?

if loadfont $prefix/font.pf2 ; then

set gfxmode=800x600

elif background_image /splash intel_iommu=on.png; then
set color_normal=light-gray/black
set color_highlight=white/black
else
set menu_color_normal=cyan/blue
set menu_color_highlight=white/blue
fi

insmod play
play 960 440 1 0 4 440 1

I've added the string in both config files (menu.cfg and grub.cfg) and then I have rebuilt the ISO with cubic but the preseed file has been ignored by the graphical debian installer.

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.

If this shall be the solution then the files to change would probably be
isolinux/menu.cfg
boot/grub/grub.cfg

The isolinux configuration serves when booting by legacy BIOS or EFI
legacy mode. For booting via EFI native mode you need to modify the grub
configuration.

Have a nice day :)
