I am trying to install Ubuntu from a usb, and I want to do the dual boot option with windows 7. I have used the demo version from the usb but I want to put it on my computer permanently. I get the step that asks me if I want to do the dual boot option (I click yes). Then the installation guide says that I need to restart the computer to continue. Once I restart the computer, the installation guide just takes me back to the first step and asks if I want to try Ubuntu out or install it. It is just spinning me around in circles.
Any help would be greatly appreciated. Sorry I am complete newbie and dummy when it comes to this.
