I confirmed this bug for my insprion 15 (3521) with ubuntu 13.10 just instllaed alongisde windows 8.1. Partition for ubuntu has been made by gparted with ubuntu live cd.
I refuse to disable "Secure Boot" for windows. I work-around the bug by going to "system option" from grub etc ... to find a windows bootable partition in there instead of using grub entry. Please fix this. I gues it's ubuntu specific. -- 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
