I'm thinking of laying pine flooring in my newly purchased house. Today there is laminate on the concrete, can I lay it on the laminate? I think it's laminate anyway, otherwise, it's a thin parquet(?). It is 100 in plum and does not creak. I don't quite understand how to fasten such a plank floor? You can't nail straight into the concrete, can you? Where do you nail in the plank? In the tongue or? How do you get the next one to fit? I know there are lots of questions, but I would appreciate help with any of them at least.
No, you cannot attach a solid pine floor to a laminate floor that is floating on concrete. Check, for example, http://www.woodia.se/rekommenderade.php?pvar=0.24178222194314 where there are descriptions of different laying methods suitable for different substrates.
You nail/screw at a 45-degree angle into the groove. Check the link above for pictures.

Thank you for your response, unfortunately, I didn't quite find what I was looking for on your link. I agree with you that it shouldn't be placed on the laminate, underneath there's probably concrete - to complicate things even more, I forgot to mention that there's underfloor heating there as well 
. Is it best to lay thin battens (like joists) and nail into them? Gluing is probably not preferable? Grateful for your response.
