A:AnswerYou may or may not need to update bios. If you get the box that says compatible with 5000 series it's a coin flip but doing so isn't that hard. Without that statement printed on the box, it is a given that you'd have to update bios...
A:AnswerYes, but it’s finicky. Install all new drivers and bios from MSI website & make sure your widows updates are up to date. Bluetooth icon will appear in tool box but may or may not work. If it’s not working but icon is showing: depower and power system till it starts working (unplug PSU and hold power button to make sure it’s totally depowerd). I did this myself after finding solution through google.
