Not sure if i copied loopback.cfg into the grub dir, or if it reads it directly from the iso, but i belive it does read it directly from the iso.
Boot.
This boots the iso, as one would expect, except for using syslinux. So the kernel and initrd from the iso are used, the disk is booted and the os installed.
So yes, this looks very much like a bug and should be re-opened/fixed.
P.S. I did not try burning the iso to disk, I used the usbcreator and grub only.
So at the moment, I'm quite happy to be running gnome-session-fallback (hate unity) on stock 12.04 (for now) WITH!! PAE kernel.
I've also made a new USB stick, using grub2 and loopbacking the ISO.
Here is what I did to an empty formatted 2GB USB stick using the LiveDVD iso (liveCD was same result) and mounted at /mnt.
grub-install --no-floppy --root- directory= /mnt /dev/sdb
grub-mkconfig > /mnt/boot/ grub/grub. cfg
Replace all menuentries with the following one.
menuentry "TITLE" { /ubuntu- 12.04-dvd- i386.iso
iso_path=
export iso_path
search --set --file $iso_path
loopback loop $iso_path
root=(loop)
configfile /grub/loopback.cfg
loopback --delete loop
}
