Hello! For those, who are interested in my discovering with bootcd, I attached a screenshot of the message, the installer told and why grub can not be installed. It might explain more.
However, I suppose, there are not many people in the world, building a live-system + installer + bootcd on it and want to install this. I believe, the package bootcd is only known by very few people at all. But as we are always want to improve things, I feel it important, to tell about this problem. As I said before: Dunno, whom I should file a bugreport! Anyway, take a look at the picture and you know more. For me, it looks like a dependency problem.... Have fun! Hans
