An Easy Way To Boot ISO Image From Your Hard Drive

With grml-rescueboot there is an easy way to boot an ISO image from your harddisk to test other linux distributions.
Out of curiosity I downloaded the iso from elementary OS ( elementaryos-stable-amd64.20130810.iso ).

First install grml-rescueboot as root :

apt-get install grml-rescueboot

Then move the ISO image to /boot/grml/ as root :

mv elementaryos-stable-amd64.20130810.iso /boot/grml

Update Grub 2 with the following command as root :

update-grub

Reboot and you will see a new entry in your booting list.
