Make sure that the HDD is made available as a bootable device in the BIOS, like Bob said. Boot from CD, let it copy the files from CD to HDD, let it reboot and start the installation from HDD, until it's finished (it should be asking you about product activation and turning on automatic updates, otherwise the installation did not complete).
