Have you tried booting another boot cd no matter which one?
If you are sure that your boot process is ok (you can use hiren's boot cd, or windows boot cd, or some live distro like ubuntu, knoppix, or so, to verify this), then check the burned iso cd (i suppose that that you have burned in the right way the iso image into a cd). Look if it has correct structure, if you run it over windows it let you read some pdfs and so. When you are sure that the cd is ok, and the boot from cd works fine on your computer, then try to do the install again. Otherwise look for some kind of error and copy and paste it here, so we can have a better idea of the problem
