I'm long-term Linux user. Now I have to install Windows 8 on my laptop which never ever ran Windows before. (Well it came with windows preinstalled but I didn't use it at all).
I don't have any kind of license key or anything, I suppose I either removed the sticker with it either it didn't come with sticker in first place. Laptop is Asus N750jv, and it came shipped with 8.1Pro I think, not sure tho.
What do I do to be able to legally install the Windows?
