I am not sure if this is hardware or software related, but it is driving me up a wall.
I started with a MacBook (February 08 model) with no hard drive.
I added a hard drive in, and since I didn't have a OSX install disc on hand I installed Windows 7 on boot. It installed fine, but I couldn't install bootcamp drivers due to not having OSX handle my install.
I then acquired both a Snow Leopard and Lion install disc. I booted with the Lion disc, and it gave me the Apple logo with the gear loading animation, but eventually the Apple logo changed into a 'no' symbol (the circle with a line going diagonally through it).
I then tried the Snow Leopard disc. It booted and showed the Apple logo with the loading gear, but would then load into a black screen.
I tried doing research (spraying the optical drive with compressed air, tried booting from a USB drive), but nothing helped. I then installed Lion from another OSX machine to the hard drive via USB enclosure. When I put the hard drive back in, it loaded the Apple logo and went to a black screen again. When I powered off the unit and restarted it, it acted like it was restoring a session and I could see the set up screen. It froze like this. I then powered down again, and it gave me three beeps and refused to boot anything. I pulled out the hard drive and reseated it (along with the RAM), and it does the boot into black screen thing.
I have no idea what to do. I tried putting in the Windows 7 disc again, and I am put into a blank screen with a flashing underscore.
Any help would be much appreciated.
