Booting an ISO on your hard drive is useful for testing new versions of Ubuntu without using up a CD. It is quicker than using a live USB tool such as UNetBootin or Ubuntu Live USB Creator.

Steps

Download the bootable disc image from here.

Install GRUB2 if it is not already installed. Type the following command into the terminal: sudo grub-install --root-directory=/media/grub2 /dev/sda.

Add a menu entry for your Ubuntu ISO. Here are a few examples. Type the following command into the terminal: sudo gedit /etc/grub.d/40_custom and paste these menu entries to the end of the file. Replace /PATH-TO-UBUNTU-ISO/FILENAME.iso with the appropriate path. On my system it would be /home/myUserName/Downloads/lubuntu-natty-i386.iso=====menuentry "Ubuntu 10.10 Desktop ISO" {loopback loop /PATH-TO-UBUNTU-ISO/FILENAME.isolinux (loop)/casper/vmlinuz boot=casper iso-scan/filename=/PATH-TO-UBUNTU-ISO/FILENAME.iso noeject noprompt splash --initrd (loop)/casper/initrd.lz}menuentry "Linux Mint 10 Gnome ISO" {loopback loop /FILEPATH/linuxmint10.isolinux (loop)/casper/vmlinuz file=/cdrom/preseed/mint.seed boot=casper initrd=/casper/initrd.lz iso-scan/filename=/FILEPATH/linuxmint10.iso noeject noprompt splash --initrd (loop)/casper/initrd.lz}
