I have a powerbook g3 pismo, mac os x 10.3.9 installed, and I am about to upgrade it to Tiger. But aparantly there is something wrong with the disk. When I put the disk in my powerbook, i double click "install mac os x", and it says to restart. So i do, but the Install program doesnt show up (no language selection,etc). I even tried holding down the "c" button at startup but the same thing happens. Basicly it will just boot into Panther, nothing more. Can anyone help? I would apprciate it.
