this is the other Klaus here :-) I don't know a direct answer to your "How could it happen?" question. Grub "knows" about other OSes through os-prober. When you run update-grub, then the script /etc/grub.d/30_os-prober is invoked, searching for other installed OSes. Unless, that is, the variable GRUB_DISABLE_OS_PROBER is set to true (for instance in /etc/default/grub). So, things to check on your box are: $ whereis os-prober $ apt-cache policy os-prober $ grep PROBER /etc/default/grub Any clues? -- Klaus -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe".
