UEFI:NTFS is a UEFI bootloader application that enables booting from NTFS or exFAT partitions on UEFI systems lacking native drivers for these filesystems. It is primarily designed for use with Rufus to create bootable USB drives with Windows installation media or Windows To Go. The bootloader loads a filesystem driver (NTFS or exFAT), mounts the target partition, and chain-loads the standard UEFI bootloader from that partition. The source code is clean, well-commented, and demonstrates careful handling of UEFI firmware quirks, such as driver conflicts and Secure Boot validation. The project compiles with either gnu-efi or EDK2, supports multiple architectures (x86, x64, ARM, ARM64, RISC-V, LoongArch), and includes Visual Studio and GCC build configurations with CI pipelines. While the code is not reusable outside of UEFI development, it serves as a high-quality reference for writing UEFI applications and chain-loaders.
