I installed 10.6.3, and after that my macbook c2d 2.0 will not start up. The startup screen has a flashing file folder with a question mark on it. I did some research, booted up using my OS X disk, and ran disc utility to repair permissions, reset the PRAM, but no dice. It sees the drive no problem, and I can even choose it to be my startup drive, but it doesn't start up. Any thoughts? I shoulda backed up before I updated; my latest backup was probably from thursday so I think I lost some data. Another question, if i reinstall OS X using archive and install, it should "recover" my files wouldn't it? I'm thinking of trying that next.
