Knoppix installation...

[Markus]

Yes, it was the one on hdb5 I was interested in.
You can comment out the unnecessary ones for windows:
# other=/dev/hda1
# label="Windows(hda1)"
other=/dev/hda2
label="WinXP/2K(hda2)"
# other=/dev/hdb1
# label="WinXP/2K(hdb1)"

I've always had windows on hda1 so I'm not really sure if you need hda1 or hda2???
You could of course leave them uncommented to try which one boots with:
other=/dev/hda1
label="Windows(hda1)"
other=/dev/hda2
label="WinXP/2K(hda2)"
# other=/dev/hdb1
# label="WinXP/2K(hdb1)"

And then do:
- Boot cd
- open a terminal
- type: mount /dev/hdb5 /mnt/hdb5
- type: sudo su (cr@p! I think I forgot this before)
- type: chroot /mnt/hdb5/
- type: cd /
- type: kedit /etc/lilo.conf (make the changes)
- type: lilo -v
- type: ctrl-d (to exit from chroot)
- type: ctrl-d (to exit from su)
- reboot

What exactly does lilo look like, and why didn't it work the first time? DO you have to enable LILO to start up or something after installing it?

why didn't it work the first time?

Can't say. Which Knoppix version are you using? Some fixes were made to the installer after the first 3.4 was released. Not sure if Lilo was included in the fixes.

DO you have to enable LILO to start up or something after installing it?

No. It's supposed to run at bootup after being installed.

What exactly does lilo look like

If you mean the graphical part of Lilo in action, it's just a splash picture with a menu. Although you can also add some kernel parameters in Lilo.
If you mean mine, this is it after I snipped off some outcommented irrelevant parts:...

# /etc/lilo.conf - See: 'lilo(' and 'lilo.conf(5)',
# --------------- 'install-mbr(', '/usr/share/doc/lilo/',
# and '/usr/share/doc/mbr/'.

# case it installs in the MBR, and will overwrite the current MBR.
