If you have a reasonably fast Internet connection (or plenty of time) and a CD burner, the easiest way to get an Ubuntu Desktop CD is to download an ISO image. To download an ISO image, go to their Web page at www.ubuntu.com/download, select a mirror site in your country or one that’s closest to you in general, and select the Desktop CD that is appropriate for your computer system. Save the downloaded ISO image to a file, burn that ISO image to a CD once the download completes, and you are ready to go!
