imac and os9 issue

[fenderguitar21]

I bought a imac 333mhz with 160ram and a 6gb hdd. it came with os 9 installed and i wanted to put os 10.3 on it. and it worked. i relized it was going way to slow. so i had a friend help me put os 9 back on. but when it formatted and installed i set the startup disk to my hdd and click restart. but when it restarts it shows a folder that flashes a question mark and than it shows the "mac happy face" and that just continues and doesnt boot up. the jumper settings were never changed and no hardware wasnt changed.

how can this be fixed?

thanks
