I'm a newbie to LInux. Basicly, WINXP hasn't been working correctly, and I want to use knoppix to, in a way, replace it.

I'm new around partions and such, and i' sure i'll mess up the process somehow. I don't want to delete WinXp for various reasons, instead I want to have a dual boot system with Knoppix and Windows.

WinXP is already installed, and I have about 20 gigs of space left. Can someone give me some pointers for this?
