hi guys, Unfortunately I now need to use windows occasionally for work and I want to install Windows 10 usual virtual box on my Mac but haven't a clue. I have a genuine copy of Windows 8 on disc and Microsoft are still doing the free upgrades to Windows 10, however I don't have a disc drive to install it. I've read online that I can download Windows directly from Microsoft however they appear to only be Windows files. My question is, how do I download Windows on my Mac so that I can install it using virtual box? Also can I then easily upgrade it to Windows 10 using virtual box?
