Ubuntu is distributed on four 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
256MB 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 256MB 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 two 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.
UNR USB image
This USB image allows you to run Ubuntu Netbook Remix (UNR) from a USB
storage device without installing UNR on your computer. While running in
this "live" environment you will be running a full desktop environment and
have the option to install UNR permanently, as well as installing UNR alongside
an existing operating system. This USB image is optimized for netbooks with
screens up to 10". You will need at least 256MB of RAM to install
from this image.
There is one image available:
- PC (Intel x86) UNR USB image
- 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.

can be found below.

CD Burning Guide or the
USB Image Writing Guide.
