As it doesn't seem to say windows is on the system, it may not be loaded at all. That laptop could run windows or linux. And if it never did more than boot to bios, then it suggests that it doesn't have windows on it. I'd ask that question.
Though if it were me, I wouldn't care, as I'd put linux on it myself.
Then windows should work on it with no problem. Just a matter of either installing it or booting from an external drive, if that's possible these days.
Thanks. Incidentally while others are finagling backup to the cloud, onto external drives etc I just clone my solid state drive (formerly HDD) onto another one with a docking station. No restoration needed EVAH.
