No Joy with CD or DVD install,where's that hammer?

[Pet-240]

ok no joy with the cd again, the dvd won't load on my Dell either but the Dell will load Ubuntu(already done previously) so current state is reload windows onto acer, update bios and disable any software raids available, then try the reload from dvd, if no joy then reload Kubuntu from live cd and then try the cd install, if no joy am not sure where to go!!!

If anyone can see anythin I'm doing wrong here, your assistance would be much appreciated!!!
