Select an image

Ubuntu is distributed on three 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 384MiB of RAM to install from this cd.

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

64-bit PC (AMD64) desktop CD
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 i386 images instead.
32-bit PC (i386) desktop CD
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.

Server install CD

The server install cd allows you to install Ubuntu permanently on a computer for use as a server. It will not install a graphical user interface.

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

64-bit PC (AMD64) server install CD
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 i386 images instead.
32-bit PC (i386) server install CD
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.

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

64-bit PC (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, 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 i386 images instead.
32-bit PC (i386) alternate install CD
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.
