Yes, it seems like your cd has some errors (maybe it wasn't burnt ok, maybe the downloaded file is bad and you have to download it again). If you can't start the cd, make another bootable cd or download the image again. (Remember you have to create the image with the iso, not just create a cd with an iso file inside of it.) If you do that ok, you'll be able to boot from the cd. Once you get to boot it, choose the option that lets you do a check on the entire cd, so you are sure there aren't errors on it (so there are no broken packages, and that kind of thing). Only after that, start the live cd, and then install from there.
