I have just got a new motherboard (MSI 970 Gaming) and I am trying to download Windows 7. I have got two hard drives one is a 1TB Seagate and the other is a 40GB WD which is primarily for installing the OS. The problem is every time I try to install Windows on my 40gb HDD, I get a message that says 'Windows is unable to install to the selected location'. I never had any problems with my old motherboard, can someone help me out please.
