Knoppix install problem

[k100]

Hello everyone, I'm having a problem installing Knoppix. Knoppix won't install with "knoppix-installer" Even Sudo knoppix-installer won't work. I have made a Linux partition and a swapfile.
When I start the installer I become the message that I have no rights to write to the harddisk and with "sudo" I recieve the message that there is a partition problem. I really like to use knoppix on my harddisk. I am a windows user who like to try something else. I hope that someone can help me.
Greeting from Henk (Holland)

Lets try this way.

Boot with knoppix cd.
Unmount all hdd partition.
Open konsole and run:
su
knoppix-installer
