I've got a MacBook Pro from 2008 with an Intel Core 2 Duo. I installed Ubuntu 10.10, then installed Debian 7 Testing. Debian 7 was fine, but for some reason the red and blue were swapped (green was fine). I decided I was tired of this, after endlessly trying to fix it, so I figured I would go back to using Mac OS X.
I booted the computer with an install DVD of both Mac OS X 10.6 and 10.7 with the same results. It gets to the last 10% of the installation process, then says Installation Failed. I restarted it, and it only shows the blinking question mark folder.
I've tried to go back to installing Linux (Debian and Ubuntu varieties). Pressing the C key doesn't make it boot from the disc. I can hear the drive spinning away, but it won't boot from a non-OSX install disc. I've also tried the Apple SuperDrive from my MacBook Air, and that hasn't worked either (though I could hear it spinning too).
Any thoughts? I've got a MacBook Pro which can't seem to have any installed on it. Within the Mac OS X boot disc, I've used the Disk Utility app to make sure the hard drive was fine, which it is.
I did have this idea, what if I could book the MacBook Pro into target disk mode and mount the drive on the MacBook Air. Then, run an installer from the MacBook Air onto the MacBook Pro. I don't have high hopes but maybe it could work.
