Did you hold down the C key "at the chime" when you boot from the OS disc. The flashing ? means no system can be found. You will have to reformat the HD if you boot from the cd before you can install the Mac OS.

That 8.6 can't be an upgrade disk: it has to be a retail copy or the original install discs that came *with that computer.*
