I copied down the iso images to CD but I am unable to boot with the iso images,
You need to "burn the ISOs", not just copy them.
See
http://www.ibiblio.org/pub/Linux/distributions/e-smith/docs/howto/CD_burning_howto.php3
for instructions (it has detailed instructions for some popular CD burning applications)
Good luck,
Andro
