Desktop image

The desktop image allows you to try Ubuntu without changing your computer at all, and at your option to install it permanently later. This type of image is what most people will want to use. You will need at least 1024MiB of RAM to install from this image.

For 64-bit ARMv8 processors and above.

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.

For 64-bit ARMv8 processors and above.

For POWER9 and POWER10 Little-Endian systems.

For IBM System z series mainframes, such as IBM LinuxONE.

Netboot tarball

The netboot tarball contains files needed to boot the Ubuntu installer over the network.

For 64-bit ARMv8 processors and above.
