How do I...?

I have just started using the Knoppix live cd and I would like to install it on my hard drive. I have read information on how to do this but I'm just wondering if it would be possible to dual boot the newly installed Knoppix with the Gentoo that is already installed on the hard drive and if so, how to do it.
I have noticed that while using the live cd that it is showing all the stuff that is already on the drive so could I actually share the disk space between Knoppix and Gentoo?
I'm a complete nOOb (as they say) so go easy on me :0)

Never mind, I tried it anyway and accidentally wiped out the Gentoo root partition. Oh well, it only took 3 days to install. At least Knoppix installed ok.
