Jocr13,
Please try the CD you received in several other computers. If several computers cannot read the contents of the CD, then it's a pretty good assumption that the CD is defective and should be returned to where you purchased it.
If all the computers but yours can read the CD, then your CDROM drive is defective or not installed properly.
Older CDROM drives can read all manufactured CDs but some have trouble reading burned CDs. Also, some older CD drives can read CDs fine but cannot boot a computer. Is this what you are trying to say?
