Download Ubuntu 11.04 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 are four images available, each for a different type of computer:  

Download 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.

Download 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.

Download 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.

Download Mac (PowerPC) and IBM-PPC (POWER5) desktop CD

For Apple Macintosh G3, G4, and G5 computers, including iBooks and PowerBooks as well as IBM OpenPower machines. Warning: This image is oversized (which is a bug) and will not fit onto a standard 700MiB CD. However, you may still test it using a DVD, a USB drive, or a virtual machine.
