    That method will work as long as none of the installation files you're copying over isn't above the 4 GB file size limit of FAT32.
    Ten-odd minutes ago, I successfully booted my PC in UEFI mode from a USB flash drive with an NTFS partition containing Windows 10 installation files. The 4 GB file size limit does not apply to NTFS.

    The UEFI specification does not require a UEFI computer to boot from NTFS. The specification only requires the computer to boot from a FAT file system. Therefore, relatively few UEFI computers will boot from NTFS.

    I don't think I understand what you're saying here . . . did you actually partition a flash drive? (I'm sure it can be done, but why would I want to?)

    I know that I mistakenly told Rufus to use NTFS and when I was finished, it would not boot my UEFI computer.

    Sorry for my terrible English. I am a poorly educated Chinese guy.

    Yes, I did. The first and the second are in NTFS and FAT32 respectively. Both can be accessed on my Windows 10.

    Have you ever tried to boot your UEFI computer from NTFS?

    I just did. Motherboard is an Asus Crossblade Ranger. USB drive MBR partitioning one partition marked as active. When the partition is FAT32 the computer will boot it in both UEFI and CSM modes. When the partition is NTFS, it will boot in CSM mode, but booting it UEFI mode drops me back into UEFI setup. Behavior which is absolutely consistent with the UEFI specification.

    Bottom line is if you want compatibility with all computers meeting the UEFI specification, the boot partition needs to be FAT12, FAT16, or FAT32. Other UEFI computers may boot different filesystems, but they are not required to by UEFI specification.

    And again:

    UEFI:NTFS - Boot NTFS partitions from UEFI

    UEFI:NTFS is a generic bootloader, that is designed to allow boot from an NTFS partition, in pure UEFI mode, even if your system does not natively support it. This is primarily intended for use with Rufus, but can also be used independently.
    In other words, UEFI:NTFS is designed to remove the restriction, which most UEFI systems have, of only providing boot support from a FAT32 partition, and enable the ability to also boot from NTFS partitions.
    This can be used, for instance, to UEFI-boot a Windows NTFS installation media, containing an install.wim that is larger than 4 GB (something FAT32 cannot support) or to allow dual BIOS + UEFI boot of 'Windows To Go' drives.
    As an aside, and because there appears to exist a lot of innacurate information about this on the Internet, it needs to be stressed out that there is absolutely nothing in the UEFI specifications that actually forces the use of FAT32 for UEFI boot. On the contrary, UEFI will happily boot from ANY file system, as long as your firmware has a driver for it. As such, it is only the choice of system manufacturers, who tend to only include a driver for FAT32, that limits the default boot capabilities of UEFI, and that leads many to erroneously believe that only FAT32 can be used for UEFI boot.
    However, as demonstrated in this project, it is very much possible to work around this limitation and enable any UEFI firmware to boot from non-FAT32 filesystems.

    I hope motherboard manufacturers will use the demonstrated workaround, so that the "4GB install.wim" limit will disappear.

    It really is quite easy now to create a usb drive that will boot in uefi with install.wim > 4GB.

    This assumes you have a custom iso with customised install.wim

    1) Create two partitions from disk management
    a) fat32 size c. 1GB
    b) ntfs - rest of drive

    2) copy all files from iso to ntfs partition

    3) copy all files EXCEPT install.wim to fat32 partition.

    That's it.

    Why not copy ONLY install.wim to the NTFS partition, as all other files will be copied to the FAT32 partition?

    What does "c." stand for? The drive letter?
