Torgo,

I believe I get the same errors as you during knoppix-installer.

I am using an HP Pavilion ze4145 (notebook). Windows XP is installed first (60GB HDD), then I used qtparted to squeeze a 10GB partition for Linux. I first installed Mepis easily, but the desktop was ugly and slow. Now I am trying to install Knoppix 3.8... but ...

I tried sudo and su with the same error results. I tried the link you provided, too. What was your solution, Torgo?
