DOWNLOAD LINUX UBUNTU

This directory contains the most frequently downloaded Ubuntu images. Other images, including DVDs and source CDs, may be available on the cdimage server. See also the list of download mirrors.

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:

PC (Intel x86) 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.

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 Intel x86 images instead.

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:

PC (Intel x86) 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.

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 Intel x86 images instead.

Alternate install CD

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

• setting up automated deployments;
• upgrading from older installations without network access;
• LVM and/or RAID partitioning;
• installs on systems with less than about 384MiB of RAM (although note that low-memory systems may not be able to run a full desktop environment reasonably).

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

PC (Intel x86) alternate install CD
