Title:
  GRUB fails to boot Windows when SecureBoot enabled

Status in “grub2” package in Ubuntu:
  Incomplete

Bug description:
  Computer with preinstalled Windows8. SecureBoot enable by default.

  1) User installed Ubuntu13.04 64bit.
  After install and reboot, GRUB appears, allows to boot Ubuntu correctly, but the Windows entry fails.

  2) Used Boot-Repair's Recommended Repair, which added some Windows entries in /etc/grub.d/25_custom

  No entry allow to boot Windows

  3) Disabled SecureBoot in the UEFI firmware, then ran Boot-Repair's Recommended Repair, which purged grub (and shim and linux-signed) then installed grub-efi.
