I had successfully booted my notebook with grub2 40_custom menuentry method. I found it very useful to keep backup of OS especially since i have low speed internet but when I try this in desktop it is not working.
Yells me with kernel panic. Not syncing trying to kill some process.
thats all i could remember.
plz help.
menuentry "Ubuntu 12.04.iso" {
set isofile="/ubuntuiso/ubuntu-12.04-desktop-amd64.iso"
loopback loop (hd0,1)$isofile
linux (loop)/casper/vmlinuz boot=capser iso-scan/filename=$isofile noprompt noeject
initrd (loop)/casper/initrd.lz
}
