Well that did not work too - the solution was to install a new rescue system (with the help of the full functional usb stick of a friend who also owns a dockstar) and then I was able to install a new debian. If someone has the same issue I can provide an image with a debian squeeze (created with dd of a 4G usb stick). -muzy-by muzy - Rescue System
