Boot LiveCD iso from grub2

[phenest]

I found an article regarding the loopback feature of Grub2 where by you could boot from an iso. Does anyone know if it's possible, if so how, to do this with the Ubuntu Live CD?

The article you linked to and the one it links to ( http://michael-prokop.at/blog/2009/0...iso-via-grub2/ ) have pretty clear instructions. What part of the process is not working for you?

I would start by putting your iso in a known (such as boot) location and altering the line from the example from isofrom=/dev/sda1/grml/grml-small_2008.11.iso to isofrom=/dev/sda1/boot/myjaunty.iso (or whatever you called it).

Something like this:

menuentry "Ubuntu Jaunty Live CD" {
loopback loop (hd0,3)/steve/archive/iso/linux/karmic-desktop-amd64.iso
linux (loop)/casper/vmlinuz isofrom=/dev/sda3/steve/archive/iso/linux/karmic-desktop-amd64.iso root=/dev/sda3 boot=casper quiet splash noprompt
initrd (loop)/casper/initrd.lz
}

...just drops to a busy box.

Something like this:

menuentry "Ubuntu Jaunty Live CD" {
loopback loop (hd0,3)/steve/archive/iso/linux/karmic-desktop-amd64.iso
linux (loop)/casper/vmlinuz isofrom=/dev/sda3/steve/archive/iso/linux/karmic-desktop-amd64.iso root=/dev/sda3 boot=casper quiet splash noprompt
initrd (loop)/casper/initrd.lz
}

...just drops to a busy box.

Did you verify the /casper/initrd.lz path and name on the image you are using? It is /casper/initrg.gz on mine. Also, try it without the root directive. How did you arrive at boot=casper? Did you try live?

[phenest]

On Karmic, it's initrd.lz, whereas it's initrd.gz on Jaunty. I've tried both Jaunty and Karmic with varying different options with no success.

boot=casper was taken from the boot options for Ubuntu.

The best I get is a BusyBox prompt.

I couldn't find this topic earlier so I opened a new one on this subject. I found out how to boot pmagic using grub2 loopback.

I also just updated the Grub2 Basics thread here. Not sure why I continue to sync the two, but for now they are.
