reinstalling Windows Me

I am working on my old computer which has Windows ME as
its OS. I think I deleted a system file because now it
will not boot up at all (not even in Safe Mode). I have
the original Window's ME CD. My question is: How do I
reinstall Windows ME from the CD or do I have to copy it
to a floppy disc and then use that? and if so how do I
use a floppy to reinstall the OS? Or does anyone have any
other suggestions? Thanks for any suggestions. C
