[solved] Knoppix don't reconigze my partition

[melofabiano]

Hello,

I'm trying to install knoppix on my computer, but knoppix-installer just recognize one partition (sda3). In this partition i already have a system installed (Ubuntu Linux), so i want to install knoppix in sda1, but the installer don't give this option.
In sda1 i have windows xp installed now... I have to do something with the partition-type for the correct recognize? Some "cheat-codes" in the initialization? What i must do?

I just make the partition using cfdisk, instead of gparted.
