As you can see from the comments on this bug this is something of a pain. I am guessing but i really think about a third of the problems with booting MS installs that show up on the forums is due to the installation of grub on the MS boot sector.
While I do not have that problem as I will not have MS in the house, I do try to sort this out for folks because I really like the new grub. Something needs to change here or we are going to drive a lot of good folks somewhere else. -- Ubuntu grub2 dist-upgrades result in confusion https://bugs.launchpad.net/bugs/576724 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
