I would like to purchase downloadable windows 8.1: http://www.microsoftstore.com/store/msusa/en_US/pdp/Windows-8.1/productID.288401200?icid=L3_Nav_Store_windows81_011415
My plan is to install it using unetbootin. But the page says:
Important: Windows 8.1 full version is for Windows 7 users only.
Currently running Windows Vista or XP? You will need to buy Windows 8.1 on DVD and perform a clean installation.
I don't understand that, why do I need any windows at all? I want to perform clean install, not upgrade. What is difference between downloadable version and box version? I don't want to order box version because of slow shipping and so on, I don't even have DVD drive. Is it possible to install the downloadable iso using unetbootin?
