It seems rather like a chicken-and-the-egg problem, which came first? you can't install ntfs-3g until you've installed the system, and it won't notice the windows partition(s) there until you've installed ntfs-3g. But it sets up the grub config at install time, so you get a system apparently without windows support. A newbie (which I'm not) would certainly find this confusing/disheartening.
