Here is a grub menu entry that can boot ubuntu from an iso image


menuentry 'Try ISO BOOT' {

set isofile="/Isos-Installers/ubuntu-14.04.1-desktop-amd64.iso"
loopback loop (hd0,11)$isofile
linux (loop)/casper/vmlinuz.efi boot=casper iso-scan/filename=$isofile noprompt noeject
initrd (loop)/casper/initrd.lz

}


============



Notes:
1. The image is ubuntu-14.04.1-desktop-amd64.iso
2. Its in /dev/sda11 In directory Isos-Installers
3. Only installers that use casper can do this (not sure it works for debian)
4. This can also be done from a grub-installed USB; You'll probably need to add
   insmod uhci
   insmod ahci
   insmod iso9660
