Okay, so I go get diskwarrior to fix my HD, becuase its keys are out of order. During startup it would show me a mesage saying master.passwd couldnt be found. I run disk warrior, and it still does this. So I try to archive and install 10.2 preserving users, and the os x installer crashes. So the in just archive and install 10.2, and then when it starts up it doesnt get to the rotating arrows. So then I erase my Hard drive and do a clean install of os x 10.2. Now when I boot up my mac cant find any valid operating systms. What's going on?
