I want to create the ISO file of Windows 8 Pro using the Windows8-Setup.exe on my Windows laptop and then transfer it to my Macbook so I can install it using the Boot Camp Assistant. The problem is that when I open the EXE setup, it asks you to enter the product key first before being allowed to create an ISO file. Will entering the product key here count it as activated? I don't want to activate it on my Windows laptop, only on my Macbook.
