Title:
  GRUB2 fails to detect/add Windows entries on a UEFI system

Status in os-prober:
  Confirmed
Status in grub2 package in Ubuntu:
  Fix Released
Status in grub2 source package in Precise:
  Won't Fix

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.

  *********************** WORKAROUND **************************

  either boot Windows from the (EFI) BIOS menu, or add valid Windows
  entries via Boot-Repair.
