Select an image
Ubuntu-Server is distributed on two types of images described below.
Server install image
The server install image allows you to install Ubuntu-Server 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.
Warning: This image is oversized (which is a bug) and will not fit onto a standard 703MiB CD. However, you may still test it using a DVD, a USB drive, or a virtual machine.
Netboot tarball
The netboot tarball contains files needed to boot the Ubuntu-Server installer over the network.
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 can be found below.
If you need help burning these images to disk, see the Image Burning Guide.
