It all started with a faulty update that screwed my MBP three ways to hell. And now I bought a new hard drive, a Western Digital (WD500BEVT), and now I can't install either the Snow Leopard CD or the 13 inch Install CD I tried holding option before start up but only the mouse cursor shows. I tried holding C but all I get is the CD coming back out. Oh and I put the CD in and shut off the MBP then turn it back on before doing those steps. Any help would be appreciated. Thank you!
