Before you start

Important Apart from the hard disk space mentioned in this article, the computer’s first primary system partition must also have 30 MB of free hard disk space. The first primary system partition is the disk volume that contains the hardware-specific files that are required to start Windows. For example, the primary system partition contains the Ntldr file, the Boot.ini file, and the Ntdetect.com file.

If you are installing Windows XP SP3 on one computer, you can select from several installation methods. Each method has different space requirements, depending on the location from which you want to install the service pack.
