ok i tried this :

- boot the Knoppix CD
- start konsole
- su
- mount /mnt/hdXY (XY=your linux / device and partition)
- chroot /mnt/hdXY
- lilo -v (or /sbin/lilo -v)
- Ctrl-d (three times to exit chroot, su and konsole)
- done

but when i did the chroot thing it said it cant be found in the /etc/bash i think it was. plus i dont know what konsole is
and su ???
