Hey guys, I'm trying to install Snow Leopard which I bought over at best buy. I bought a new hard drive for the macbook pro, put it in, I turn on the computer and pop in the Snow Leopard DVD and it seems like it does this cycle where the DVD spins up 3 times and then the computer finally just ejects it. I thought the DVD was bad, luckily I bought 2 retail copies, put the other one in....same problem. I have a copy of Leopard, I put that in, sometimes it will do the same thing, spin up 3 times and eject, but then it finally booted from the DVD and with about 8mins left to install it fails, because even with the Leopard DVD near the end up the install, the computer keeps spinning the the DVD and stops, then the install finally fails. Are there any suggestions you guys may have? I reset the PRAM and SMU but it didn't help. Thanks!
