So I bought a new MOBO its the MSI FXA990 gd-80. It now wont boot with windows xp. I have also bought a copy of windows 8.1 and instead of booting from the HDD I am now trying to update my OS in order to see if it will boot from that. As I update my OS it stops on "getting started" after the initial updating restart. Any tips on how to get this to work? What to do first?
