I just recently finished building my new PC. At first this message would show up:

"Reboot and Select proper Boot device or Insert Boot Media in selected Boot Device and press a key."

So i got a Windows 7 USB from my friend and now whenever i boot with the USB, the only thing that shows up is a black screen with a blinking white dash and it just stays there. Please help?
