Instead of extracting contents from an ISO image, GRUB and GRUB2 have been able to boot from ISO images directly through a loopback device. On Windows versions prior to Windows 8, you press Windows/Super+ R to open the run menu and open diskmgmt.msc, that would open Disk Management.

Use the latest AMD64 (LTS) ISOs, because these definitely contain UEFI bootloaders.Don't forget to create a partition after you've created the partition table.A GPT partition table like in preinstallations of Windows 8 and later is recommended.

You may still need to explicitly tell your computer to boot the media via UEFI.Remember that for an installation or booting the media: Just copy the files to your FAT32-formatted USB drive. Creating UEFI-only booting USB live media is pretty straight forward.
