I got the way with the boot.ini file now!
I installed Knoppix on hda7 now and the Swap Partition is hda6.
Installed Knoppix with Lilo in the root partition of Linux.
Also I edited the boot.ini and I can choose also Linux now on booting up.

But when booting Linus it still stops at the bootup screen showing not more than:
L
That's all.
What damed problem do I have???
