A friend of mine recently installed windows to another drive (I hadn't had the chance to tell him to unplug every other drive) and sure enough, it did install with all of the funny partitions elsewhere. We though it will be easily fixable afterwards, but it's not - you cannot recreate it. With those gone the system cannot hibernate and it couldn't shut down until disabling fast startup. Updates don't work either, but it still tries doing them, fails rollbacks and restarts. Is it user error? Maybe, but I still blame the installer for not being clear and automatically picking a stupid setup.
