    Mac is attempting to start from network

     

    Goto System Preferences > Startup Disk

     

    Set it to the disk where the operating system is installed

     

    This is called Macintosh HD unless you changed it

    You can try to reset PRAM by

     

    1. Shut down your Mac.
    2. Locate the following keys on the keyboard: Command (⌘), Option, P, and R. You will need to hold these keys down simultaneously in step 4.
    3. Turn on the computer.
    4. Press and hold the Command-Option-P-R keys before the gray screen appears.
    5. Hold the keys down until the computer restarts and you hear the startup sound for the second time.
    6. Release the keys.

    Resetting NVRAM in Open Firmware

    If your computer is Open Firmware-based and you are unable to reset NVRAM as described above, you may alternatively reset the NVRAM and Open Firmware settings using the steps in the Solution section of Message “To continue booting, type 'mac-boot' and press return”.

    In some cases, an Open Firmware-based computer may not respond to the keyboard commands noted above, and may not allow starting up into Open Firmware by pressing and holding the Command, Option, O, and F keys during startup.  If you are unable to get to an Open Firmware prompt (and your Mac supports doing so), try holding the power button held down continuously during start up.

    Then try to boot from the CD again.

    It is begining to sound like something more serious then anything she could have done. It sound like your Mac is no longer able to reach either the disk or the optical drive. It might be time to call in Apple for help on this one.
