Bug#756253: Upgrade from 2.02~beta2-10 to 2.02~beta2-11 left grub unbootable

[Mike Hommey]

Package: grub-efi-amd64
Version: 2.02~beta2-11
Severity: critical

After the upgrade from 2.02~beta2-10 to 2.02~beta2-11, a reboot just got
me under Windows. The EFI boot menu had two entries for Windows (I don't
think it had two in the past, but maybe it did, and that's not related),
and one for "UEFI OS" which was set as the default. Choosing that one
manually in the boot menu still brought Windows up.

After booting with a USB stick in rescue mode, deleting the duplicate
Windows entry and the UEFI OS entry, and re-running grub-install, grub
showed up at reboot. After grub-install, the EFI entry is now named
"debian".

Note I haven't run grub-install in a while, so I'm not sure what version
of grub had done a grub-install last.

Hardware is Dell XPS 12.
