It’s not a huge pain when you have a motherboard with proper UEFI support and some basic EFI shell knowledge. You just need your thumb drive with an FAT32 filesystem, put the netboot EFI binary on it, boot into the shell and execute the binary. You will need a LAN cable for this because WiFi is not supported in UEFI (AFAIK). The netboot binary will download the ISO image into memory and start it right away. An even better solution is to create the path “/EFI/BOOT/” on the thumb drive and rename the netboot binary to “BOOTx64.EFI”, put it into the folder and your BIOS will boot it automatically at startup. If not, you can select it as a valid boot partition in the BIOS menu.

It’s a tower defense mobile game called Grow Castle.
