Yes, using grub2, boot with example below......

menuentry "Livecd  " {
	loopback loop (hd0,10)/pop/ubuntu-10.04-desktop-amd64.iso
	linux (loop)/casper/vmlinuz boot=casper
iso-scan/filename=/pop/ubuntu-10.04-desktop-amd64.iso noprompt noeject
quiet splash initrd (loop)/casper/initrd.lz 
}

In above example, iso file: ubuntu-10.04-desktop-amd64.iso is at
partition (hd0,10), folder 'pop'. (no 'home' in example, if at home,
then (hd0,10)/home/you/xxxxx).

It will boot like a livecd from cdrom and continue to install as usual.

Good luck - Goh Lip
