Since this bug was filed, the shim signed bootloader has been updated several times in Ubuntu. Please test with a clean install from either Ubuntu 13.10, or a daily image of Ubuntu Trusty, to check whether this problem still exists with current versions.
Also, you say the bootloader did not install when you used manual partitioning, and you subsequently used a third-party tool to configure the bootloader. The missing bootloader is probably caused by a wrong partition "usage" choice, and we can't support the output of the third- party recovery tool. Please use the guided partitioner to install Ubuntu side-by-side with Windows 8. If there are bugs in that standard install path, we need to know about them and fix them; and if your manual install went so badly that the bootloader wasn't installed, we need to rule out the possibility that the chainboot problem is related to this. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1091464 Title: Unable to chainload Windows 8 with Secure Boot enabled To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/1091464/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
