Select an image
Ubuntu is distributed on two types of images described below.
Server install image
The server install image allows you to install Ubuntu permanently on a computer for use as a server. It will not install a graphical user interface.
Choose this if you have a computer based on the AMD64 or EM64T architecture (e.g., Athlon64, Opteron, EM64T Xeon, Core 2). Choose this if you are at all unsure.
A full list of available files, including BitTorrent files, can be found below.
If you need help burning these images to disk, see the Image Burning Guide.
