So the website has given me the key and a link to iso download for 64bit professional. But my new pc doesnt have a dvd drive so im forced to use USB. When I try to create a bootable USB using the windows media creation tool, it doesn't give me the option for Windows 10 Pro? Only Windows 10, Windows 10 N and Windows 10 Home. If i click windows 10 and proceed to enter the professional key will it work? Also if I move the iso the website gave me to the usb will it be bootable? please help guys!!
