If you already have Windows installed on your hard disk drive and do not wish to overwrite it with Ubuntu Linux you should read the [[Installing Ubuntu Linux on a Windows System (Dual booting)]] chapter and [[Installing Ubuntu on a Windows Disk with Wubi]] chapters of this book.

To start the installation, place the Ubuntu Linux CD into the CD-ROM or DVD drive and reboot your computer system. If the system loads the old operating system, or complains it cannot find an operating system to load you will need to change the boot order in your system BIOS. To do this reboot again. Early in the boot process the BIOS will display a message indicating which key should be pressed to enter Setup. Press the key indicated so that the BIOS Setup menu appears. Navigate the menu system until you find the setting which indicates the boot order used by the BIOS. Change the order so that the drive containing the Ubuntu Linux CDROM is listed before the hard disk drive, then exit and save the settings. Reboot once more and you should find that Ubuntu Linux loads from the CDROM. Once Ubuntu has loaded you will be presented with the following screen:
