1) Is the CD burned right? When you insert it into another PC, you should be able to see a few files (including a Welcome.exe) on the CD when you open it in My Computer.
2) Did you use the right medium? You probably should have burned this onto a CD-R (instead of DVD-R). If that doesn't work, try using a DVD-R instead.
3) Is the laptop configured to boot from the CD? This is typically done by pressing a key when you first turn your PC on to select the boot device, or else entering the BIOS and configuring it from there.
