After we were victims of poor installation and have surfed long for related problems, here comes the guide for a successful start: It sounds crazy but you must be logged with no profile. So you log in and puts Disc 1! Now the prompt should appear for installation. Is it at 100% specifies a Disc 2 but does not include the tray !!! Log in now with your profile and closes the disc. Now everything should work. Hope I could help you
