This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.

What program are you using to burn the cd? What version of Ubuntu are you using right now? – djeikyb Feb 13 '11 at 10:10

Maybe CD is damaged? Try to boot ISO image on VirtualBox. If it works, CD media is probably damaged. Possible reason might be that your CD/DVD drive is dirty or broken. If you cannot boot ISO image in VirtualBox, downloaded ISO image might be corrupted. In this case, try to calculate checksum of ISO image, and compare to md5 checksum on ubuntu page where you downloaded your ISO image.
