Hey there, So I have been using a successful 10.6.2 build on a p55-UD4 board for the last three months now. I have had no issues, but this morning when I went to boot, I got the little spinning curser you get just before boot loader appears. Then it froze. I thought, no worries, I have a drive I backed up with carbonite for this very reason, I'll just get it to point at that drive. SAME PROBLEM!, the curser freezes and no boot for me. Being a paranoid person, I also had a third drive backed up with a working install, for the very unlikely event that the second disc fails, and you guessed it, I can't boot from that either. Which leads me to think it must be something in my BIOS or hardware. The only thing is I haven't changed anything, and it's been working flawlessly for months... Can anyone offer any suggestions, on how I might get my system up again!
