Title:
  os-prober doesn't detect Windows properly with EFI and MBR partition

Status in os-prober package in Ubuntu:
  New
Status in os-prober package in Debian:
  Fix Released

Bug description:
  https://anonscm.debian.org/cgit/d-i/os-prober.git/tree/os-
  probes/mounted/x86/05efi#n42..n45

  Disk has regular MBR table. It has Windows 7 and Ubuntu installed on
  different partitions. Os-prober doesn't detect EFI partition on MBR
  table because "udevadm info" returns "dos" partition scheme instead of
  expected "msdos".

    $ udevadm info /dev/sda1 | grep  dos
    E: ID_PART_ENTRY_SCHEME=dos
    E: ID_PART_TABLE_TYPE=dos

    $ fdisk -lu /dev/sda | grep -B1 -A1 ef
       Device Boot      Start         End      Blocks   Id  System
    /dev/sda1   *        2048      616447      307200   ef  EFI (FAT-12/16/32)
    /dev/sda2          616448   128134439    63758996    7  HPFS/NTFS/exFAT

  Fixing conditions below resolves the issue:

  -		\( "$ID_PART_ENTRY_SCHEME" != gpt -a "$ID_PART_ENTRY_SCHEME" != msdos \) -o \
  +		\( "$ID_PART_ENTRY_SCHEME" != gpt -a "$ID_PART_ENTRY_SCHEME" != dos \) -o \
  		\( "$ID_PART_ENTRY_SCHEME" = gpt -a "$ID_PART_ENTRY_TYPE" != c12a7328-f81f-11d2-ba4b-00a0c93ec93b \) -o \
  -		\( "$ID_PART_ENTRY_SCHEME" = msdos -a "$ID_PART_ENTRY_TYPE" != 0xef \) ]; then
  +		\( "$ID_PART_ENTRY_SCHEME" = dos -a "$ID_PART_ENTRY_TYPE" != 0xef \) ]; then
