I am trying to install Windows 8 to a 101 gb partition. After the whole begginning of checking your computer to install Windows 8 (I have Win7) it goes straight to Installing Windows 8. It doesn't ask if I want to upgrade or custom. I can't make it install onto the partition. It doesn't open any menus. It just starts installing Windows 8 and then I have to cancel it. Someone please help. Do I just have to wait some more for it to ask me and show the menus?
