ReactOS reaches major milestone with NTFS install support

ReactOS is a volunteer-built open-source operating system that aims to run Windows programs and drivers without Windows. It can now install onto an NTFS partition, the filesystem used by most Windows PCs, instead of requiring a separate FAT32 drive. The new driver still lacks caching, journaling and security support, so it is a development milestone rather than a ready replacement.
