Well, if nothing else you can certainly read it and see what it is putting in there. If you page down you'll hit the actual menus which are readable enough. While the autogenerated menus are fairly complex, the reality is that grub2 is able to handle simple configuration files the same way that grub1 was. The format is slightly different though. So, that is always a fallback. However, I'd check /etc/defaults/grub to make sure you don't have it set to suppress UUIDs. That will, obviously, suppress UUIDs. -- Rich
