If we are installing Windows 8.1 or Windows 10 on a UEFI system with a GPT disk, we must select a 'GPT partition scheme for UEFI.' After that, we click on the disc icon and choose the ISO image.
Rufus will automatically change the File system to NTFS, which is a prerequisite for creating a Windows USB. It will also change the volume label to ESD-ISO.

We just need to right-click on the ISO and select the 'Burn disc image' option.
Then, it's just a matter of selecting our DVD-R drive - in which we should have an empty DVD-R or DVD-RW - and click on 'Burn.'
