A retail copy or one you bought off eBay? You should be aware that the copies on eBay are often the ones supplied with new Macs. These are specific to the model and will not install on other Macs. For example, a disk from an iMac will not work with my mini.

Please clarify what you mean, sir. Are you referring to a second-hand disc as ijack mentioned, a retail disc or restore CD/DVD you bought personally, your original CD/DVD, or from another source? From there, it will be much easier to assist you with this issue. :) Also, note: a) You cannot boot off of and do a clean install with an Upgrade-only disc or drop-in-place upgrade in most cases and b) the C key must be held down right after the chime to boot off a CD that is bootable. Lastly, are you trying to install OS X, or upgrade OS X? Please clarify. Thanks.
