Windows partitions incorrectly detected as duplicates

[Thomas Ward]

The grub os-prober is incorrectly detecting the windows system partition as a valid bootloading device and is detecting the windows "System Reserved" partition created by the Windows installer and the system partition. It is also labeling them the same way, which adds duplicate entries.

NOTICE: There may be similar bugs to this one, however i do not have a recovery partition (installed on a *clean* drive by myself using a full install disk from Microsoft)

Ubuntu 12.04
Package: os-prober.

I will add additional details, including `apt-cache policy` and `lsb_release -rd`output later, as I am not reporting from my Ubuntu system right now.
