Microsoft makes a Windows USB Install Tool:

This will create an EFI bootable USB drive with Windows install files on it. Just go to the link, and download your copy of Windows onto the USB stick. Restart with the stick in your computer, go to the Boot Menu, and select USB. You should be good to go. If it doesn't boot, you may have an issue with EFI booting, so try BIOS/Legacy boot instead.
Thank you so much. I will go to the link.
Do you know where I can buy Windows keys?
