Windows won't install on new SSD

I rarely ask for help. I am always the one to help others, but this time I need help. I have tried everything and can not get windows to install on my Alienware M11x R2. I installed a new 512GB SSD, but windows will not install. Windows loads files, and then the PC reboots. The only OS I can get to install is Ubuntu, but I don't like it. I want windows 7 back on. Any Ideas?
