[Bug 1022064] [NEW] os-prober detects HP's recovery environment as Windows Vista (loader)

[Albert Pool]

Public bug reported:

I have an HP laptop where Windows Vista came preinstalled. It has a
recovery partition. But that partition is detected as Windows Vista
(loader) instead of Windows Recovery Environment.

The partition's label is HP_RECOVERY. On Windows only one file is
visible on the partition, called HP_RECOVERY, but if I mount it on
Linux, all of the partition's content is visible. When mounted on Linux
(udisks --mount /dev/sda4) it looks like a normal recovery environment,
with folders such as boot, HP_RECOVERY and Windows.

Using Quantal's os-prober didn't change anything.

$ sudo os-prober
/dev/sda1:Windows Vista (loader):Windows:chain
/dev/sda4:Windows Vista (loader):Windows1:chain

On sda1 I have my Windows, sda4 (originally it was sda2) is the recovery
partition.

I know that there are also Windows 7 users who have a recovery partition
that's detected as a Vista loader.
