Please help with questions related to windows/bootcamp.
So, I understand the basics of bootcamp, but how would I buy windows, and how would it work? Like, I download the ISO file, run bootcamp, set it up, all that. Then the Mac boots into the windows, where you need to enter the product key. Do we just buy a product key from microsoft? Or do we have to buy a download version of windows, what would the differences between say, a download, a disk, and a flash drive, and how would we set that up with bootcamp, which method do we use the downloaded ISO version for?
Thank you!
