[QUOTE="nkobel, post: 1244876, member: 203210"] My Macbook Pro 5,5 is not booting up when I turn on the computer. When I insert the Install OSX disc and load both Disk Utility and/or System Profiler, the hard drive to which OSX is installed is not being listed in any sense. The contents in System Profiler for SATA say "NVidia MCP79 AHCI" with nothing listed, and then it has it listed again with the DVD drive and Install disc, but no hard drive. There is not 3rd party hardware, but I did partition my drive for Windows and Linux a while back. Though I removed those OSs, the Windows partition remains but was not conflicting with the OSX install. The other day I noticed my computer froze, so I restarted it. It took a few minutes to boot, and then froze again. This time it didn't boot but flashed the question mark folder at startup. It would boot only occasionally into OSX. I was able to boot the Install disc into Disk Utility and Verify Disk said my disk needed to be reformatted. I then tried repairing the Windows partition which may have written something to my disk to make it disappear, because now it's not being recognized. I tried the firewire connection with another Mac, but that didn't recognize anything but the Install disc. Strangely enough, the sudden motion sensor (SMS) seems to not be functioning at the moment, though it was before. And what else is weird is that when I try to "install Mac OSx" via the Install disc, it does not recognize the disk drive there either! Any ideas? I've tried the firewire connection, resetting the PRAM, resetting the SMC, and of course the OSX Install DVD Disk Utility. Best, Nick [/QUOTE]
