1. Turn on the computer and open the DVD player.
2. Load the Win XP installer and then reboot again the computer.
It would give you a message "Hit any key if you don't want to boot from the CD", in this case, DO NOT hit anything so that the computer would boot using the CD.
3. Run through the installation (the instructions should appear on the screen).
4. Put the product code when ask.
5. Win XP should be installed now.
You should have also the necessary drivers for the video, sound and LAN card so that you could attain the best performance of those components.
Have a great day!
