I face the same problem on an Ultrabook Series 5 laptop and confirm that items 8 and 9 do work as a workaround as described.
However, after realizing this, I started digging into a riddle why Ubuntu fails to load the 'samsung-laptop' kernel module in the UEFI mode and actually bumped into bug #1040557, a bug that should have been flagged 'nuclear' instead of 'critical,' as comment #114 puts it. Hence I decided to stop at this point for the time being and wait for reports that it is safe to use Ubuntu on my machine. -- 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
