Thank you. Well, let’s not call it fiddling, let’s rather say I chose to boldly go where no man has gone before. I thought it should be a piece of cake to boot the partition from a bootable CD in case something goes wrong. With Kubuntu, I searched for menu.lst globally, but found only two files ending with menu.lst (some example files). I mean, Grub is still there, it just doesn’t let you do anything else than boot Windows.
