Public bug reported: Since the upgrade to grub version 2.02~beta2-29ubuntu0.2, Secure Boot in Windows 8 UEFI mode fails to launch GRUB, instead it falls back to the Windows boot loader. In order to be able to dual boot I have had to switch to Legacy Secure Boot. (These are the terms used in the ASUS UEFI Bios Utility)
I have attempted to downgrade the packages grub-common, grub-efi-amd64, grub-efi-amd64-bin and grub2-common to 2.0~beta2-29 but this did not solve the problem: I recall that the Muon Update manager put up a notification about changes to other packages when the upgrade appeared but I cannot remember what the dependent packages were. ** Affects: grub2 (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1527311 Title: grub2.02~beta2-29ubuntu0.2 fails in Windows 8 UEFI Secure Boot To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/1527311/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
