Step 1 – download

Ubuntu is distributed, free of charge, in the form of a downloadable DVD image. This image is available from the Ubuntu website at http://ubuntu.com/download/desktop. On this page, you can download either the latest development release or the latest LTS releases. I would suggest starting with the LTS release, Version 12.04, as this is the version that this book is based on.

The following screenshot is an example of the choice between the latest development release and the LTS release:

As seen in the preceding screenshot, Ubuntu downloads are separated by latest features against LTS. Also, notice the drop-down menu on the right side, allowing you to select the 32-bit or 64-bit versions. Select the release and 32-bit or 64-bit option best suited to your machine, and select Get Ubuntu.

The speed of your download will vary based on the speed of your Internet connection. While you're waiting for your download, you have a good opportunity to ensure you have everything backed up on your current system.

When your download is complete, use any DVD burning software to burn the image to a disk. These applications may vary based on your current operating system. Most new systems simply allow you to right-click on the Ubuntu .isofile, and select Burn image to disk....

It is important that you use the option of burning the image to disk and not simply write the .iso as a file to the disk. The former will boot properly and load the installer, while the latter will simply create a file on the disk.
