How to Replace Mac OS X With Windows XP

1. Run Boot Camp Assistant on your Macintosh computer. Find this program in the Applications/Utilities folder.
2. When Boot Camp loads, click the 'Partition' button. When it is finished creating the new partition (it will take several minutes), a new screen will appear giving you the option to 'Quit and Install Later' or 'Start Installation.'
3. Insert your Windows XP installation disk in the CD/DVD drive and select 'Start Installation.' OS X will shut down and the Windows XP Installer program will load from the Windows XP disk. You will see a blue screen listing your OS X partition, your new Windows partition and a third line that says 'Unpartitioned Space.'
4. Use the 'D' command to delete all partitions on the disk until only the 'Unpartitioned Space' line remains.
5. Press 'C' to create a new partition in the unpartitioned space.
6. Select your new partition and press 'Enter' to install Windows. You will be prompted to format the partition.
7. When formatting is finished, click 'Next' and Windows will be installed on your computer.
8. When Windows is finished installing (this will take 30 minutes or longer), eject the Windows XP disk and insert the OS X installation disk. Boot Camp will load automatically and install any needed drivers.A message may appear on your screen saying the software has not passed the Windows Logo testing. Select 'Continue Anyway.'
