Not that I have any idea if this is an issue or not, but on those machines, was Windows shut down properly before you installed, or was Windows Hibernated?
I'm not sure, in cases of hibernation in Windows, that the partition is mountable, which may be an issue here. I'll try to recreate this though and see if I can get it to happen. How exactly did you upgrade? Did you do it via network (do-release- upgrade or Update Manager) or did you do it with one of the ISO images (which one?) -- Unable to access non-Ubuntu loaders from GRUB2 menu in Lucid https://bugs.launchpad.net/bugs/571893 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
