Are you able to start up the computer from the 9.1 or 9.2.2 CDs that you have? It's possible that they are update only CDs or not for your computer (e.g., software restore CDs for some other model). Try starting from the CD by pressing and holding the "C" key until the computer is obviously booting from the CD. If that works then try looking -> here . Otherwise, you may have to start with your former 9.0.x and update it to 9.1 -> <>

Good luck.
