you will have to make a bootable USB then use the appropiate windows installation creation tool from the windows web site
HERE is a link on how to do it on a PC, I have zero clue how you are going to manage to do it on an inferior mac, know anyone with a loaptop you could use for 30 mins( if that)?
when installing you will obviousy have to go into the bios, and make sure that the first boot device is from USB and you will have to choose the correct option to just use an unactivated version of windows, but if you care, you can pay to activate it later on
