Want to design a loopback code to boot the Debian 9.11.0 Live CD image
with first the legacy grub2, and then alter the HCL laptop menu-list
with the latest Grub.
Written a code, by mounting the Debian Live ISO, reading the necessary
files and using clues therein, but still can't boot the Live Debian
CD:

menuentry "Debian GNU/Linux Live (kernel 4.9.0-11-686)" {
set isofile="/incomplete/debian-live-9.11.0-i386-lxde.iso"
loopback loop (hd0,msdos4)$isofile
linux (loop)/live/vmlinuz-4.9.0-11-686 boot=live components splash quiet
initrd (loop)/live/initrd.img-4.9.0-11-686
}
#############################################
submenu "Debian Live with Localisation Support" {
set isofile="/incomplete/debian-live-9.11.0-i386-lxde.iso"
loopback loop (hd0,msdos4)$isofile
menuentry "English (en)" {
linux (loop)/live/vmlinuz-4.9.0-11-686 boot=live components

initrd (loop)/live/initrd.img-4.9.0-11-686

Old Grub2 is stalling after a while, resulting in barebone linux CLI.
a) Are you aware that the Debian Live images contain a hybrid CD/HDD setup
so that they can be written to usb drive as-is, and be booted from it
immediately?
b) When creating a multi-live usb drive myself, I found the easiest way is
to just copy vmlinuz, initrd.img and filesystem.squashfs from the .iso
image and put these files into a separate directory on the usb drive. No
.iso file on the usb drive, no grub-loopback needed. The grub command then
looks like this:
linux /debian/live64xfce/vmlinuz boot=live components
live-media-path=/debian/live64xfce quiet splash
initrd /debian/live64xfce/initrd.img
The live startup script will search for a file named
${live-media-path}/filesystem.squashfs on any mountable drive.
