my motherboard is a msi 970a-G45

You can't do that, it's not reinstalling Windows. You need to do it on your machine. Download proper W7 same as yours was, make a bootable USB or DVD with it and start installation like that.

As has been previously mentioned, you need to create a bootable usb (or dvd) put a win 7 ISO on there same as yours was home, pro etc. you will need to get a copy of your licence code (hoping there is a sticker on your machine somewhere or you will need a new one)

Good luck,
Matt.
