Hi mcc.

The iso image is just a command-line shell. It's intended for use on low-end systems. Typically, any 64-bit system should be powerful enough to run the full ubuntu desktop live environment along with the graphical desktop - for example on a live USB stick. You can easily install the ubuntu-rescue-remix-tools metapackage from the PPA.

To do so, add the following archive to your software channels:

Copy the line below and adding it to your system's software sources.

deb http://ppa.launchpad.net/arzajac/ppa/ubuntu karmic main

Then authenticate this software source by running the following command:

sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys BDFD6D77

Then, install the "ubuntu-rescue-remix-tools" package.

But there is an advantage to using the 32-bit version. Some of the tools included on the live image do not compile on 64 bit.
