Is it possible to install Knoppix on the same partion as Windows (or a partion that is not empty and shouldn't be deleted)?

I know about these two boot options but are they safe?

knoppix tohd=/dev/hda1 Copy CD to HD partition and run from there
knoppix fromhd=/dev/hda1 Boot from previously copied CD-Image

and would this option make it possible to boot from a floppy:

dd if=/cdrom/KNOPPIX/boot.img of=/dev/fd0 bs=18k

if I modify it like this:
dd if=/dev/hda1/boot.img of=/dev/fd0 bs=18k


The best solution to me would be if it is possible simply to copy knoppix on the hdd and to make an option for the Windows boot manager for booting knoppix. I don't want to mess with lilo or my system in any way.
