OK, if anyone can know what will happen.. ? I got a laptop which supports two hdd. On one hdd I installed windows 7 but without the other hdd attached to the laptop. And ive done the same way with the other hdd and i install windows 8 on it. Now what am worried a bit if I plug both hdd to be both at the same time inside the laptop will damage any windows? or it will give me the option to choose what OS to boot?
