Help Knoppix Installation

[MacBee]

I was trying to install Knoppix 4 on my friend's PC having only XP installed, with NTFS partitons.Unlike in my PC with FAT32 file system ,when i gave knoppix-installer command,It prompted a window with only two options
1.Partition your Hard disc
2.Quit
What may be the problem??
please tell me how to proceed?

Linux canot safely write to NTFS,
you will have to make room on his hdd for a linux filesystem.
say 4-6G free or so.
