I thought you were trying to install Windows onto your MacBook
If you're just trying to install it onto a computer that originally came with Windows 8 then that's easier.
1) Get the ISO.
2) use the ISO to make a bootable USB installer
3) boot from the USB and install using one of the keys from this page

You need the correct key for the specific version of 8.0 that your computer came with. If you don't remember just do a google search for your laptops specs and it should tell you.
Those are installation keys only and will not work to activate a valid license.
Your actual license will be hard coded into the bios of the laptop and Windows will auto-detect it and auto-activate as soon as you get it connected to the internet.
Since the computer came with Windows 8.0 you can save yourself a lot of trouble by getting an ISO of 8.0 and forget about 8.1 for now.
Once you've got 8.0 installed you can then go to the Microsoft store and download the free upgrade to 8.1.
