Sounds weird, but here's the deal. I've got a Win10 laptop. It has an unused additional HDD slot. And I got my hands on an unused laptop, so naturally, I took it apart. Now I've got a 750gb HDD which would be a shame to throw out, so I want to add it to my laptop. But the HDD has Windows on it.
So my question is, is it ok if I just slap it in? Or will my laptop get a brain freeze from 2 drives with an OS on each of them?
