I was doing some repairs with Norton Utilities on a tray loading Bondi Blue iMac and everythng was going fine until it crashed in the middle of doing something!!!!!!!!!!

It now bongs but then shows the customary flashing "?" on a folder and won't start.

It was running OS 8.5.1

What I want to know is would an OS 7.x startup disk work as long as it had the right system enabler? or do I need one with an OS 8 system folder?

I am up a bit of a creek as I have no system disks with this machine!
