Hey Stalker,
As with what the other good people said, 9 times out of time Windows 10 will work on many older boards.
The manufacturer may say "Supports Win 7" or "Supports up to Win 7" but in truth Windows 10 should work just fine. My board is certified for windows 7 yet runs windows 8/8.1 and Windows 10 just fine.
Once windows 10 is installed, windows update should automatically download and install your Motherboard's drivers. If it does not you can also manually install them by going to your Mobo's manufacturer site and downloading the software yourself.
As for BFV, it runs just fine on Windows 10.
A lot of us are a testament to that fact!
Feel free to contact me if you need help.
