Need help booting from iso via grub

[Snowhog]

I want to be able to boot GParted (latest) from grub so I don't have to burn a LiveCD/USB. The following 40_custom file isn't working.

#!/bin/sh
exec tail -n +3 $0
# This file provides an easy way to add custom menu entries.  Simply type the
# menu entries you want to add after this comment.  Be careful not to change
# the 'exec tail' line above.
# menuentry "Name of OS here"{
#       set root='(hd0,x)'
#       configfile /boot/grub/grub.cfg
#}
menuentry "Gparted live" {
      set isofile="/home/paul/Downloads/ISOs/gparted-live-0.22.0-1-amd64.iso"
      loopback loop $isofile
      linux (loop)/live/vmlinuz boot=live config union=aufs noswap noprompt ip=frommedia toram=filesystem.squashfs iso-scan/filename=$isofile
      initrd (loop)/live/initrd.img
    }

After I select Gparted live from the grub menu, the first error says it cannot find the iso. The set isofile= entry is correct.

Don't you have to tell it the partition?
Something like

[S]loopback loop $isofile[/S]
loopback loop (hd0,5)$isofile

[Snowhog]

This gets me as far as asking about the keyboard map and what language I want, and the video detection, but then it never runs x, so I'm left with a black screen and a blinking underline in the upper left corner.

menuentry "GParted Live" {
      set isofile="/boot/iso/gparted-live-0.22.0-1-amd64.iso"
      loopback loop (hd0,5)$isofile
      linux (loop)/live/vmlinuz boot=live config union=aufs noswap noprompt vga=788 ip=frommedia toram=filesystem.squashfs findiso=$isofile
      initrd (loop)/live/initrd.img
      }

I created the directory /boot/iso (sudo mkdir) and copied the iso (sudo cp) to that directory.

There may be some ideas and details here:

I haven't read or tried any of this with GRUB2. Also note the occasional notes if you have UEFI (re efi).

Thanks, but still a no-go. Still the same results as I noted in post #3.

I can boot gparted, and it prompts me for language, input, and video parameters. Then, when trying to start X, it fails no matter what resolution or driver I choose.

Thanks Mike, but that's for when you boot from a LiveCD/USB and are at the graphical menu after a successful boot.

Other posts I've found on the 'Net concerning booting the Gparted iso from your HDD complain too, about x not starting. Haven't found a solution yet.
