Thank you Tysz... Of course I do that. I have been using Apple for over 20 years
did you try holding down the option key? This leads you to the startup screen. That way you can tell if the mac recognized the cd/dvd.
Clean media. Clean optical drive. Buy cleaning cd/dvd.
Does it show as a boot choice if you hold the alt key?
What is the 2z691-****-A number on the Disc?
Thank you BDAqua
The number is 2Z691-6327A
Suddenly a few years ago the computer refused to recognize the start up disk. I contacted Apple and they sent me another copy. It did not recognize the new copy, although it recognizes other CDs/DVD's!!! I cannot even erase my hard drive.
Thank you again

When I restart holding the option key, it will not show the start up disk....
Thank you again
Nope, it will not show a boot choice....
It should show boot choices. Doesn't it at least show harddrive?
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."

Try taking the battery out for 10 minutes. Put battery back in. Cross fingers. Power the machine back on.
