I am missing the relevance of "no floppy"....you have a CD, so you need a CD drive.
Assuming that you have free space (unpartitioned), or a partition that is unused, then simply boot from CD #1 and follow directions.
If you are unclear on the above, tell us what yoou current partition setup is. I think Vista has a partition resizing utility. Otherwise, get he GParted live CD.
and have the cd or dvd images
Which one? CD: boot from #1, DVD: boot from the DVD
