As an update to a previous post, I have finally got around to installing Ubuntu 9.04 on the desktop computer. I have a virus that has disabled Windows anti-virus software so I will be trying a workaround with Linux Ubuntu. So far the Windows installation of Ubuntu has not worked. That could be due to the virus and I will probably end up setting it up with its own partition on the hard drive. At the moment I am running it live from the CD (which is perfect for getting the feel for Linux) and it works just fine.
