Ubuntu is distributed on six 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 three 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.
- 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.
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.
There are three images available, each for a different type of computer:
- PC (Intel x86) 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.
- 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 Intel x86 images instead.
- 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 desktop image
The preinstalled-desktop image allows you to unpack a preinstalled version of Ubuntu onto an SD card. See ARM/OMAP for instructions on using this image.
There is one image available:
- Texas Instruments OMAP4 preinstalled desktop image
- For OMAP4 boards.
Preinstalled server image
The preinstalled-server image allows you to unpack a preinstalled version of Ubuntu onto an SD card. See ARM/OMAP for instructions on using this image.
There is one image available:
- Texas Instruments OMAP4 preinstalled server image
- For OMAP4 boards.
