I'm going to be purchasing a Laptop soon that comes with Windows 7 on it. But I don't want to use the harddrive that comes with the Laptop. I want to install a SSD into the Laptop and do a clean install of Windows 7 onto the SSD. Can anyone let me know exactly how to do that please? How do I get Windows 7 off of the Laptops old harddrive so I can clean install it onto the SSD? Thank you for any help!!
