ReactOS, an open source Windows alternative, can now be installed directly onto NTFS drive partitions. The move clears a long-standing hurdle and brings the project closer to beta.

What NTFS means for ReactOS

Previously ReactOS required users to keep a FAT thirty-two partition for installations.NTFS, a proprietary Microsoft filesystem, traces back to Windows NT three point one in nineteen ninety-three.

The NTFS driver still lacks caching, journaling and security support, causing inferior performance. ReactOS warned there are still potentially undiscovered bugs. Users should tread carefully before switching.

Read-only NTFS support arrived in twenty sixteen. Boot support landed on FreeLoader in twenty twenty-two. Now ReactOS can finally install directly to NTFS, completing a gap in development spanning nearly a decade.
