Does anyone know where to get the cheapest legitimate Windows 10 Home license for bootcamp use? And if I go with a DVD version as it's usually a little bit less expensive is that an okay option to use for bootcamp? Is it fairly simple to make an ISO file for installing? I've seen a Windows 10 Home, OEM DVD at B&H for $100. I've also seen some unopened discs on eBay from anywhere between $25 dollars and $60 dollars. Any reason not to go with one of those options?
