    Need help booting from iso via grub

    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.
    Code:
    #!/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
    Code:
    [S]loopback loop $isofile[/S]
    loopback loop (hd0,5)$isofile
    I'd rather be locked out than locked in.

      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.
      Code:
      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.
