I posted yesterday with a small problem and now I've got a much bigger problem. My MacBook Pro will not go past the grey screen and the spinning wheel logo. I tried resetting the PRAM...nothing, reset the power management unit...nothing. I tried booting from the Leopard DVD but it won't let me. It just goes on to get stuck on the grey screen. I did hold down C and if I press the option key it gives me the option to boot from the DVD but I still get stuck on the grey screen after that. Pretty much nothing I do will let me get past the grey screen. I've tried single-user and verbose mode too. My problems started when I was using Leopard normally except that my Time Machine backup would carry on without making any progress. I tried logging off to "reset" it and the MBP just froze on the blue screen after logout. I held down the power button to do a reboot and all of the above happened. I haven't changed any settings around or done anything unusual so I'm puzzled as to how this happened. It will let me boot into my bootcamp partition and that works just fine. Help please!
