Hi Jan, I'm confused by the way you related your problem. Your running Nortons DD on your hard disk and manipulating your extensions on your hard disk has no bearing on a CD booting correctly.
I have an OS 8 CD (I don't recall which version) that behaves the same way and I always have to boot it with extensions off (holding the shift key down). This will at least allow me to boot the CD and install the system on the hard disk. The exact sequence for you to follow would be to restart your system with the "C" key held down to force boot from the CD. The moment you see the smiling Mac face, immediately release the "C" key and hold down the "Shift" key. Once that's accomplished, the CD should boot fine (with extensions off) and you should be able to reinstall your system. Opt for a clean install if at all possible. Good Luck!
