Web search for Ubuntu 11.04 Natty Narwhal installation tutorials

While researching on how to install Ubuntu 11.04 Natty Narwhal, I came across the following useful sites:

• www.psychocats.net/ubuntu/installing
• www.ubuntu.com/download/ubuntu/download
• www.youtube.com/watch?v=zuVOikrjvAk

I'm thinking about creating my own tutorial on this topic. Even though this issue is already adequately covered by many other site, I believe this is a great opportunity for me to learn something new and especially get to know VirtualBox better.
