I can't boot my Mac in osx or safe mode. I tried everything. I dont have the installation disc. I am running 10.3.9. I tryed commands in the single user mode, But it says disc is ok, I tryed PRAM resets, still no glory. I tried to boot safe mode still has spinning gear on white apple logo screen. Any other commands i could possibly try. I do not have the original disc. This started when I deleted my web browser on mistake. PLEASE Help??!!!!
