Ubuntu 11.04 (Natty Narwhal)

Select an image

Ubuntu is distributed on five types of images described below.

Desktop CD

The desktop CD allows you to try Ubuntu without changing your computer at all, and at your option to install it permanently later. This type of CD is what most people will want to use. You will need at least 256MiB of RAM to install from this CD.

There is one image available:

64-bit Mac (AMD64) desktop CD
Choose this to take full advantage of computers based on the AMD64 or EM64T architecture (e.g., Athlon64, Opteron, EM64T Xeon). If you have a non-64-bit processor made by AMD, or if you need full support for 32-bit code, use the Intel x86 images instead. This image is adjusted to work properly on Mac systems.

Alternate install CD

The alternate install CD allows you to perform certain specialist installations of Ubuntu. It provides for the following situations:

In the event that you encounter a bug using the alternate installer, please file a bug on the debian-installer package.

There is one image available:

64-bit Mac (AMD64) alternate install CD
Choose this to take full advantage of computers based on the AMD64 or EM64T architecture (e.g., Athlon64, Opteron, EM64T Xeon). If you have a non-64-bit processor made by AMD, or if you need full support for 32-bit code, use the Intel x86 images instead. This image is adjusted to work properly on Mac systems.

Install/live DVD

The combined install/live DVD allows you either to install Ubuntu permanently on a computer, or (by entering 'live' at the boot prompt) to try Ubuntu without changing your computer at all.

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

PC (Intel x86) install/live DVD
For almost all PCs. This includes most machines with Intel/AMD/etc type processors and almost all computers that run Microsoft Windows, as well as newer Apple Macintosh systems based on Intel processors. Choose this if you are at all unsure.
64-bit PC (AMD64) install/live DVD
Choose this to take full advantage of computers based on the AMD64 or EM64T architecture (e.g., Athlon64, Opteron, EM64T Xeon, Core 2). If you have a non-64-bit processor made by AMD, or if you need full support for 32-bit code, use the Intel x86 images instead.

Preinstalled netbook image

The preinstalled-netbook image allows you to unpack a preinstalled version of Ubuntu onto an SD card. See ARM/OMAP for instructions on using this image.

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

Texas Instruments OMAP3 preinstalled netbook image
For OMAP3 boards.
Texas Instruments OMAP4 preinstalled netbook image
For OMAP4 boards.

Preinstalled headless image

The preinstalled-headless image allows you to unpack a preinstalled version of Ubuntu onto an SD card. See ARM/OMAP for instructions on using this image.

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

Texas Instruments OMAP3 preinstalled headless image
For OMAP3 boards.
Texas Instruments OMAP4 preinstalled headless image
For OMAP4 boards.

A full list of available files, including BitTorrent files, can be found below.
