Perform an "Archive and Save" installation. This choice is available during the installation procedure - look for it in the windows that appear during the installation. This will duplicate the old "Clean Install" option that was available with certain key strokes in OS-9 and below. After doing the "A&S" install, you will be back to the OS version that is on the installation CD that you use and you will have to go through all the upgrade installations again to get to where you want to be. BUT, this is better than having to lose all your data and installed software by re-initializing the drive and starting over from square one. Have a safe day, Ron
