Had the same problem on a new Lenovo X140e. Tried to wipe Windows and install 14.10 and it refused to boot, giving this error.
Installed 14.04 without problem. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1387654 Title: installing or upgrading to Ubuntu 14.10 kills Boot Manager on ThinkPad W540 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ubuntu-release-upgrader/+bug/1387654/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
