Can you please clarify this issue? Are you running on a UEFI system or a legacy BIOS system that is incapable of UEFI? Are you attempting to add a live disc to your installed system's GRUB, or are you talking about a GRUB installation on your live disk? Are you using some third-party utility to create the disc?

I mean boot to the LiveCD installation ISO from GRUB For example here are few entries that work:
menuentry 'Try Manjaro' {
set isoFile='/LiveCDs/manjaro-gnome-21.2.1-minimal-220301-linux510.iso'
set imgDisk='/dev/disk/by-uuid/2949bg8d-a603-333z-x2aw-g98f1a3c866h'
rmmod tpm
loopback loop (hd1,2)$isoFile
linux (loop)/boot/vmlinuz-x86_64 img_dev=$imgDisk img_loop=$isoFile copytoram
initrd (loop)/boot/intel_ucode.img (loop)/boot/initramfs-x86_64.img
}
menuentry 'Try Debian' {
loopback root (hd1,2)'/LiveCDs/debian-buster-mini-gtk.iso'
linux (root)/linux priority=low vga=788 toram --- quiet
initrd (root)/initrd.gz
}
menuentry 'Try Ubuntu' {
set isofile='/LiveCDs/ubuntu-21.10-desktop-amd64.iso'
rmmod tpm
loopback root (hd1,2)$isofile
linux (root)/casper/vmlinuz boot=casper iso-scan/filename=$isofile noprompt noeject toram --
initrd (root)/casper/initrd
}
I tried different things for Pop!_OS For example:
menuentry "Try Pop_OS" pop-os {
set isoFile='/LiveCDs/pop-os_20.10_amd64_intel_6.iso'
set imgDisk='/dev/disk/by-uuid/2949bg8d-a603-333z-x2aw-g98f1a3c866h'
rmmod tpm
loopback loop (hd1,2)$isoFile
linux (loop)/boot/vmlinuz img_dev=$imgDisk img_loop=$isoFile copytoram
initrd (root)/casper_pop-os_20.10_amd64_intel_debug_14/initrd.gz
}
However, I could not get it to work :disappointed:
Here's how to do what you want. From some other system, extract the file /boot/grub/grub.cfg
from the iso to the directory where you have the iso and rename is as popos.cfg
(but it could be anything). Edit that file such that the menu entry looks similar to the below (I'm using a different iso):
menuentry "Try Pop_OS" pop-os {
set isoFile='/isos/pop-os_22.04_amd64_nvidia_17.iso'
rmmod tpm
loopback loop (hd1,2)$isoFile
set root=loop
linux /casper_pop-os_22.04_amd64_nvidia_debug_275/vmlinuz.efi boot=casper live-media-path=/casper_pop-os_22.04_amd64_nvidia_debug_275 hostname=pop-os username=pop-os noprompt modules_load=nvidia nvidia-drm.modeset=0 iso-scan/filename=/isos/pop-os_22.04_amd64_nvidia_17.iso ---
initrd /casper_pop-os_22.04_amd64_nvidia_debug_275/initrd.gz
}
Now when you boot into GRUB, run from the command line the command configfile (hd1,2)/isos/popos.cfg
. Then hit escape to get back to the menu and a new menu item should have been added for "Try Pop_OS", select that.
This should get you most, if not all, of the way there. The real key is that the kernel commandline parameter iso-scan/filename=<absolute path to iso>
must be provided for the casper scripts to look for the iso as a file on some recognizable filesystem.
