Hi Alexandre, When you update your kernels, the part that runs is update-grub, which has no knowledge of Windows whatsoever. Instead, this is a script that manages the part of your /boot/grub/menu.lst file between the "### BEGIN AUTOMAGIC KERNELS LIST" and "### END DEBIAN AUTOMAGIC KERNELS LIST" markers. If you add a Windows boot entry between these markers, you're absolutely right that it will disappear on a kernel upgrade, and that this has nothing to do with Windows partitions - that's bug #21412 in grub, which has been fixed for Ubuntu 8.04.
Your symptom does not match what has been originally reported in this bug, however, so I have not presumed that this is a duplicate of bug #21412 - it appears to be a real problem with grub loading Windows at boot time, unrelated to problems with menu.lst being overwritten. -- Grub removes Windows boot option when NTFS partition needs recovery https://bugs.launchpad.net/bugs/21175 You received this bug notification because you are a member of Ubuntu Bugs, which is a direct subscriber. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
