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.

There are four images available, each for a different type of computer:

64-bit PC (AMD64) server install image
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.
64-bit ARM (ARMv8/AArch64) server install image
For 64-bit ARMv8 processors and above.
PowerPC64 Little-Endian server install image
For POWER8 Little-Endian computers, such as Power Systems S8xxL/LC Linux-only servers.
IBM System z server install image
For IBM System z series mainframes, such as IBM LinuxONE.

For ARM hardware for which we do not ship preinstalled images, see ARM/Server/Install for detailed installation information.

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.
