Why boot to the CD again, if ya had installed all the files. Did you press a key to boot from CD again? Have you reformatted ya disk, or removed the partition, to clear the incomplete OS that ya have attempted to install previously. What happens if ya dont have a CD in the drive, what error do ya get?
Ive just looked at ya sig, and noticed ya running 2 HDD's, are ya installing the OS to the correct drive? Try removing ya second drive, and installing the OS then
