    iMac G3 not booting OS 9 install cd

    I recently tried to boot the OS 9 Retail CD on my iMac G3 (slot-loading), but have hit a snag. When I press "c" to boot, it goes to a gray screen for a little while but then boots into OSX. I have tried to boot the cd from "options", resetting the PRAM, etc. What could be wrong?

    G'day and welcome to the forums.

    Is your Classic OS 9 disc a retail version and not one from a different computer? And are you putting the CD in, rebooting and holding down 'C' immediately after the chime until it starts?
    Hang on to those original install discs like grim death! Using OS X.7 or later make a bootable USB thumb drive before running Installer!

    Yes, I pressed c at start, and it is a retail cd.
