I'm looking to buy and download the "full" version of Windows 8. That is what is called Windows 8 System Builder Personal Use License. I would like to avoid having to purchase a physical copy and wait for it to arrive.
I want an ISO and a single product key for personal use to install either in a VM or a home-built PC (i.e. without any OS installed already). I thought I would get this done today and went looking for a place to buy and download this from Microsoft, but I couldn't find anything obvious. I do not have a copy of any version of Windows at home anywhere. To make things even harder, the little system I want to install Windows 8 on doesn't have a DVD drive, so I would need a way to make whatever I download into a bootable USB stick.
Is there a way to buy and download a "full" Windows 8 non-upgrade license for personal use?
UPDATE: I thought hard about buying Windows 7 Pro, but Windows 8 is cheaper. Also, sorry if this seems like a duplicate, but I haven't seen this question actually answered anywhere. Versions of it have been asked, but I haven't found a straightforward "no" or "here's where to buy this" for the home user starting from a blank hard-drive who wants to pay for and download it right now.
