Which operating system can format a disk to NTFS?

The operating system that can format a disk to NTFS is Windows. NTFS, or New Technology File System, is a proprietary file system developed by Microsoft. It is the default file system for modern Windows operating systems, including Windows 10, Windows 11, and their predecessors. This means Windows provides built-in support for creating, managing, and formatting disks using NTFS.

While some other operating systems might support reading NTFS (like Linux and Unix), they typically do not natively format disks to NTFS without additional software. In Linux, for instance, there are tools available to format drives as NTFS, but these require specific packages to be installed and are not part of the standard disk management utilities. Consequently, the inherent capability of Windows to format a disk in NTFS without any additional installations or tools emphasizes its role as the correct answer to the question.
