  grub-update fails to detect windows bootloader on a uefi system

Status in os-prober:
  New
Status in “grub2” package in Ubuntu:
  Confirmed

Bug description:
  HOW TO REPRODUCE:
  1) install Ubuntu on a computer with UEFI firmware
  2) Reboot the PC, boot into Ubuntu, open a terminal and check that the 'sudo os-prober' command does not return any Windows entry.

  REMARK: if it returns some Windows entry, but those entries are
  invalid, you may be affected by Bug #1024383 instead.
