I am trying to install windows 8 and my hard drive to install it on isnt showing up. All that appears is i can download windows 8 to is a 3.9gb unallocated space thing. Obviously that is to small to download it on. I need to it to recognize my 1tb hard drive. I correctly installed the hard drive into my computer and I am 100% sure of it.I have restarted my computer several times and went through every option. What could possibly be the problem? Please HELP!
