How did you put Ubuntu on the disc? You just can't copy the downloaded iso image to a disc. You need to burn an iso image to the disc. See this: https://help.ubuntu.com/community/BurningIsoHowto
Be sure to burn the disc at the slowest possible speed to avoid errors.
If you open the disc on a windows machine it should have multiple files and folders on it. If the disc only contains the iso image it was not done correctly.
If you want to try installing Ubuntu from a flash drive see this:
Be sure to set the computer to boot from the usb as the first boot device in the BIOS. If you are going to install from a disc set the optical drive as the first boot device.
