Bug Description

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.
