The Windows recovery and the Asus recovery are two completely different things. Windows recovery (WinRE) can be reached by pressing F8 or hold shift and selecting restart from the start menu. This recovery allows for basic repair of the Windows OS and underlying file system. The factory reset is stored on that 10GB partition and has to be accessed by the pressing one of the F# keys generally F11 when prompted at the BIOS screen. Other than seeing the partition Windows, Windows doesn't have anything to do with this partition. If it's damaged you will want to request a recovery media from Asus. This media will have the same functionality as that partition.
