The Problem: NTFS.SYS Missing or Corrupt

The NTFS.SYS file is a vital component of the Windows operating system as it helps in managing the file system and ensures the stability and integrity of the data stored on your computer's hard drive. When this file becomes missing or corrupt, your Windows 10 system may fail to start, leading to various error messages and system crashes.

The causes of NTFS.SYS missing or corrupt can vary, but here are three common reasons:

1. Corrupted File System

A corrupted file system is one of the primary causes for NTFS.SYS becoming missing or corrupt. This can occur due to abrupt system shutdowns, disk errors, virus infections, or a faulty hard drive. When the file system becomes corrupted, it can lead to issues with various system files, including NTFS.SYS.

2. Malware Infection

Malware or malicious software can also infect and corrupt essential system files, including NTFS.SYS. These infections can occur through unsafe downloads, malicious websites, infected email attachments, or compromised external storage devices. Once infected, the NTFS.SYS file can become missing or corrupt, leading to system instability.

3. Outdated Drivers

Outdated or incompatible device drivers can cause conflicts with the NTFS.SYS file and lead to its corruption or removal. This can happen when you install new hardware, update system components, or fail to keep your device drivers up to date. When the NTFS.SYS file is affected, your computer may encounter booting issues or frequent system crashes.
