That's what _I_ do, but you think ordinary windoz "dual" booters ever gonna think of that?

Strangers bring them to me already fsck'd up with no restore media to fix them with. I just set those machines off to one side, and poke at windoz when it needs a poke to continue to do what it ought to be smart enough to do on its own. Doesn't really how long it takes to me, and they leave here with no serious expectations how long it will be until I call to tell them come get it back.
