Hi

I am just starting with Knoppix, and am trying to set up a double boot system with windows XP and Knoppix. The howto I am following says I need this boot floppy later to copy some files off, to make the dual boot work.
But, the knoppix-installer won't make the boot floppy, but instead says:

knoppix@ttyp0[knoppix]$ sudo knoppix-installer

(This is the total output in the terminal window)
After this a window appears saying, Install Complete.

But the floppy doesn't work, so I can't continue.
Could anyone tell me what to do about it?

Thx,
