ReactOS Achieves Milestone: NTFS Driver Now Supports System Installation

Key points

• The ReactOS NTFS driver has matured sufficiently to handle the installation and operation of the ReactOS operating system.
• NTFS formatting support is now fully functional with this driver.
• This milestone is considered a significant step toward the project's elusive beta release.
• The driver currently lacks caching, resulting in slower performance compared to other platforms.
• Journaling and security support are not yet implemented in the current version.
• Developers warn that other undiscovered bugs may still exist in the driver.

Background

ReactOS is an open-source operating system project that has been working toward a beta release for years. In 2026, the project has achieved various technical milestones, with the maturation of the NTFS driver being the latest significant achievement. This follows a period of steady development where the project has focused on improving core system components to ensure stability and compatibility.

Why it matters

The ability to install and run ReactOS on its own NTFS driver is a fundamental requirement for a stable, usable operating system. It reduces dependency on external drivers and validates the core file-system implementation. While performance and security features are still missing, this step is crucial for the project's goal of achieving a beta release and eventual compatibility with Windows applications.

What to watch

The ReactOS team will likely focus on implementing the missing features, such as caching, journaling, and security support, to improve performance and stability. They will also work on identifying and fixing any remaining bugs in the NTFS driver. These improvements are necessary before the project can proceed to a beta release.
