Definitely, os-prober needs fuse module to work properly. D-i is trying to load the fuse module but it is not available in the d-i environment. Here is d-i log extract: Sep 11 02:15:31 anna-install: Installing ufs-modules Sep 11 02:15:31 anna-install: Installing btrfs-modules Sep 11 02:15:31 anna-install: Installing fuse-modules Sep 11 02:15:31 os-prober: unknown udeb fuse-modules When I load the fuse module manually os-prober works fine. Therefore solution for bug reports 684265, 686314, 686631, 687286 is to create fuse-modules udeb package. Patch is available here: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=684265#35 Other problems related to listing other OS's in grub menu, that may or may not be related to os-prober, are described in bug reports 587397, 603107, 608025, 608219, 609251. If you see similar problems related to LVM please file a separate bug report. Milan
