If you need a cheap Windows laptop, that would be Groupon. Post a new post asking how to shop there.
I just bought a chromebook not realizing it has the chrome O.S. I have used products fro Microsoft since I have been using computers. How do I format the SSD on my chromebook so I can install Windows 8.1 on it. My laptop is a Samsung 500 series. You can answer using my email address. Thank you.
