In 2004, I wish people requesting help will start taking the time to detail their situation and goal

If you'te under win9x/ME and your C: drive is fat, you can copy a knoppix boot diskette to some directory and start the kernel via loadlin. Knoppix should then boot as if from diskette/cd, and you can install as usual. Obviously if you have no other bootable device than your HD, you'll have to be extra careful when installing lilo.
