Your idea of booting off the OS9 install CD should work, but I doubt that if you succeed it will do you any good. Your only option would be to erase the disk and install OS9 onto the erased disk, and I suspect you do not want to do that. Still, you can try inserting the CD and choosing it as the startup disk from inside System Preferences. I can think of a couple suggestions, but they involve external drives, which not all iMac G3s support. The simplest thing would be to burn a copy of a working OS 9 System Folder from another Mac onto a CD, and copy it off the CD onto your hard disk. The gotchas involved are that: 1) It should be a version which is compatible with your iMac. 2) Any Classic components in the System Folder would be compatible with the version of OS X presently on your iMac. 3) Your internal hard disk has OS9 drivers installed on it.
