Hi, i got from a friend a lenovo L560 20F1S00J00 Q3 2016 model but with no hdd, i got a ssd but regarding windows what can i do? The model had windows 7 pro installed in the hdd (i don't have it) (probably downgraded from Windows 10 pro license, just a guess based on the Q3 2016 warranty start date) can i download windows 10 pro from Microsoft directly? What about the activation, how is going to be done (i don't see a product key although it has a windows logo)
