Press the F1 key. It should take you to the PC BIOS. If not, see what other keys are available to you that say something about "setup". Once in BIOS, you'll have to search your way to find "boot devices" or "boot order" or something with "boot". You need to tell it to boot from the CD-ROM first instead of the hard drive. Once you make that change, make sure to "save & exit" from the BIOS. Before doing this, insert your cd and then exit the BIOS. You should now be able to boot from the CD or you will see a message that says "press any key to boot from cd". Remember, once you run through the first part of the setup, you'll need to change the boot order back to the hard drive and take out the CD.
