see this:http://www.knoppix.net/docs/index.ph...HDInstallHowTo
it has tips about installing a toHD system.
To summarize:
use lilo. I'm assuming you have only one partition, hda1 (or hda1 plus a swap).
copy the directory /boot/isolinux from the cd to the hd.
you really only need the files /boot/isolinux/linux24, linux26, minirt24.gz & minirt26.gz.

Then edit /etc/lilo.conf add the following:
Code:
 image=/mnt/hda1/boot/isolinux/linux24
 label="Knoppix3.4-24"
 append="lang=us fromhd=/dev/hda1 home=scan myconfig=scan apm=power-off"
 initrd=/mnt/hda1/boot/isolinux/minirt24.gz
 read-only

 image=/mnt/hda1/boot/isolinux/linux26
 label="Knoppix3.4-26"
 append="lang=us fromhd=/dev/hda1 home=scan myconfig=scan apm=power-off"
 initrd=/mnt/hda1/boot/isolinux/minirt26.gz
 read-only
If you have another o/s, add it too. a windows entry is usually

Code:
other=/dev/hda1
label="Windows"
table=/dev/hda
run lilo to install lilo to the mbr.

That's it, you should now be able to boot into your Knoppix.
If you are unable to edit /etc/lilo.conf because of the read only file system, copy it to /home/knoppix then run lilo with
lilo -c /home/knoppix/lilo.conf
