My Mac OS X 10.6 not booting from yesterday morning. I even tried to start it in single users mode but nothing changed and I am still getting the same issue. I have no idea what happens to my system but its really very annoying for me as I have stored few very important files on my Mac OS X 10.6 hard drive. Does anyone know what do to when Mac OS X 10.6 not booting? Please help he guys out of this very critical scenario and for that I will be really very thankful to you!!!
