See the official Ubuntu 9.10 Installation Guide. The guides listed below provide additional instructions on how to install Ubuntu. Try a demo of Ubuntu on your machine by using a LiveCD (or other type of | 'Live' session)!

Requirements

• Check if your hardware works with Ubuntu and meets the minimum system requirements. (See SupportedArchitectures, UbuntuWiki:HardwareSupport and Installation/SystemRequirements).

Standard installation

• Obtain an installation LiveCD.
• If you downloaded a CD (.iso) image, burn it to a CD (see BurningIsoHowto and Installation/CDIntegrityCheck).
• Install Ubuntu by booting from the installation CD.

The standard Ubuntu desktop installation uses a Graphical Install.

Installation using the Alternate CD

If your computer is not able to run the standard Desktop installation CD, you can use an Alternate installation CD instead. The Alternate CD also allows more advanced installation options which are not available with the Standard LiveCD.
