Yes, I have a new 1 GB partition on my hdd (inside an extended partition) where
I have downloaded the GParted Live ISO file.
I want the system to use this to boot GParted Live from the boot menu.

I did this, it also installed something called memdisk into /boot
Note that my ISO file is in a *separate partition* which is mounted on
/boot/images via /etc/fstab using the UUID, so it is *not* part of the actual
partition where the Ubuntu Desktop lives.

After I have done the apt install grub-imageboot and verified that the
/boot/images dir now contains the ISO file (after mounting the GParted
partition) I ran the sudo update-grub command which found the GParted iso file.

When I rebooted there *was* a new entry in the boot menu for GParted!
"Bootable ISO Image: gparted-live-1.3.1-1-amd64"

So far so good!

But when I selected it the ISO did *not* load, instead I got an error:

error: file '/boot/memdisk' not found.
error: you need to load the kernel first.
Press any key to continue

Question:
Are your systems multi-boot with several operating systems or just one?
My contains 3 systems and I want to add a 4th, GParted Live

It seems like the memdisk file is the key here, it is put by apt into /boot on
the *running* desktop system and I don't understand how it can be accessible for
the boot unless the desktop partition is also mounted...

This seems to be the showstopper now.
