You seem to be conflating two unrelated errors. One involving mounting your windows partition from within Ubuntu, and one with booting windows. If you want to clear the hibernation file and mount the partition from Ubuntu, you need to prefix the command with sudo to get super user permissions. See http://wiki.ubuntu.com/RootSudo for more information.
When you try to boot windows, is there any error message from grub? Please run this script and add the results to this report: http://sourceforge.net/projects/bootinfoscript/ ** Changed in: grub2 (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1079482 Title: Windows 7 Not Booting To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/1079482/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
