Hi. I installed 10.4.4 today, and everything was going fine. It optimized the drive, and then asked me to reboot. I did, and during the reboot, I was stuck and the white screen with the gray apple in the middle, and the spinning thing on the bottom. I tried to reboot a few times, and the same thing happened. I can hear the drive start to boot up, click and stuff as usual, and then it just stops. I booted from my Panther disc and repaired permissions and verified the disk and stuff, there were no problems (some minor permission ones, but they were fixed). I don't know what to do now. I tried messing with the hard drive pins on the hard drive, and i currently have it set as Device 0 Master. I tried using Cable Select, which seemed to be the only other option. Boht ways give me the white screen though. I tried zapping the PRAM, booting holding the: Shift Key; Option Key, SpaceBar. Please help me! Thanks.
