I read him to say "So As To Be Bootable in ANY PC". Does that make a difference?
Your comments are misleading because it appears Rufus, which I do not use, has a UEFI to NTFS converter which is just a workaround. . UEFI does require FAT32 or it is not recognized during the boot as a UEFI compatible drive.NO, UEFI does NOT force the use of FAT32 for boot.....
GPT for a target system with UEFI (non-CSM) gets a Fat32 auto selection.The Compatibility Support Module (CSM) is a component of the UEFI firmware that provides legacy BIOS compatibility by emulating a BIOS environment, allowing legacy operating systems and some option ROMs that do not support UEFI to still be used.
SOURCE (AND Actually a pretty good read) https://www.happyassassin.net/2014/01/25/uefi-boot-how-does-that-actually-work-then/For the sake of sanity, I am going to assume the use of disks with a GPT partition table, and EFI FAT32 EFI system partitions. Depending on how deep you’re going to dive into this stuff you may find out that it’s not strictly speaking the case that you can always assume you’ll be dealing with GPT disks and EFI FAT32 ESPs when dealing with UEFI native boot, but the UEFI specification is quite strongly tied to GPT disks and EFI FAT32 ESPs, and this is what you’ll be dealing with in 99% of cases. Unless you’re dealing with Macs, and quite frankly, screw Macs.

If I remember what I read several years ago, FAT32 is required due to the bit version of the boot utilities.
Is that why the MCT/Media Creation Tool process automatically reformats any USB Thumb drive as FAT32 up to a maximum of 32GB [Windows limit] during the creation of the bootable USB Thumb drive? I mistakenly used a 64GB drive and lost use of half the drive, couldn't even create a new partition in the unallocated space, had to fully clean it to restore 64GB.UEFI does not require FAT32, period.
