    Start up the iMac and open the cd drive. Put the OS CD in to the cd tray and close it.

     

    Now restart and hold the c key down during start up.

     

    If everything works, you will see the OS installer, and you can start over with a new installation.

     

    You can select the installation language at this point.

    Actually, this means that the mac could not find a valid os on a bootable os on a device or partition.

     

    -------------------------

     

    Sometimes if volumes don't appear in Startup Manager (what you get when you hold down the Option key at startup), you need to reset the Mac's PRAM, NVRAM, and Open Firmware. Shut down the Mac, then power it up, and before the screen lights up, quickly hold down the Command, Option, P, and R keys, until the Mac has chimed twice more after the powerup chime. Then, before the screen lights up, hold down Command-Option-O-F until the Open Firmware screen appears. Then enter these lines, pressing Return after each one:

     

    reset-nvram

    set-defaults

    reset-all

     

    "The reset-all command should restart your Mac. If so, you have successfully reset the Open Firmware settings."
