It invokes a utility called os-prober, which is a separate package, and does not IMHO do a very good job of detecting anything. In particular if you have an unmaintained menu.lst in a 4-year old legacy partition that used to be /dev/hda6 and is now /dev/hda11, it will blindly generate an erroneous stanza in your /boot/grub/grub.cfg with usually puzzling consequences. > I've only used grub2 for one installation and it didn't recognize > Windows XP on my friend's machine (even though it was valid and the > hdd would boot XP), so I Google'd around a bit and followed something > similar to this > http://erickoo.wordpress.com/2009/06/14/how-to-add-vista-partition-to-grub-2-ubuntu-9-10-karmic-koala/.

I never used this capability with legacy grub either, because I had a few options in my kernel boot commands that matched my hardware, something an os prober would not know about and I didn't want update grub to overwrite my carefully crafted menu.lst. I do likewise with grub-pc, specifying what I need in /etc/grub.d/40_custom. This also ensures that if I move things around on my hard drive I'm not likely to forget modifying it and updating grub.cfg. > I don't know if grub2 is unstable, it was just easier for some people > (like myself) to edit menu.lst directly.

If you maintain your boot environment manually, there is nothing that prevents you from updating /boot/grub/boot.cfg directly and get rid of everything in /etc/grub.d/ and never run update-grub again. Just make sure you don't mix the two approaches. CJ -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe". Trouble? Contact listmas...@lists.debian.org
