Boot the computer with the 2000/XP CD in the drive and allow setup to begin. When the screen appears showing the existing partitions and unpartitioned space available on the computer you should see a drive listed in the lower portion of the screen. Now you'll see all the partitions listed that are currently on the drive. To delete all the existing partitions hit the 'D' key followed by the 'L' key. The screen instructions will be visible to guide you through the process.
Once all the existing partitions are deleted the display will show the total unpartitioned disk space.
If you only want one partition then hit enter and the entire disk space will be allocated to a single partition and you'll be taken to a screen where you select a file system.
If you want to create one partition of a specific size or several different partitions then do not hit the Enter key. Instead, hit the 'C' key to create a partition. Hit 'Backspace' until the cursor moves to the first digit location. Enter the size of the first partition to be created. Repeat the create partition process as many times as you want until either the desired number of partitions has been created or all available drive space is allocated to partitions.
Once all the partitions have been created, use the 'Up' arrow key to select the C drive partition and press the 'Enter' key to install XP to the partition. It's necessary to choose a file system and format the partition before the installation can proceed.
