MBRWizard is a free, portable command line utility designed to manage, repair, and manipulate the Master Boot Record (MBR) on Windows systems. It provides a comprehensive set of tools for diagnosing and fixing boot related problems, managing partitions, and safeguarding critical boot data through backup and restore operations. Because it runs without installation, the MBR Wizard is especially valuable as a USB based recovery and troubleshooting tool.
This lightweight utility is aimed at system administrators, technicians, and advanced users who need precise control over disk boot structures. Whether you are repairing a damaged MBR, setting the correct active partition, or preparing a bootable USB flash drive, it offers direct and efficient access to low level disk operations.
Master Boot Record Manager | MBRWizard

MBRWizard operates entirely from the Windows command line, allowing it to run even in minimal recovery environments where graphical tools may not be available. It can list and inspect existing MBR entries, repair corrupted boot records, back up and restore the MBR, hide or delete partitions, and mark partitions as active or inactive. These capabilities make it a powerful alternative to built in Windows disk tools, which often lack advanced repair features.
Because incorrect MBR changes can render a system unbootable, this tool is best suited for users who understand disk layouts and boot processes. When used correctly, it can resolve issues that would otherwise require a full operating system reinstall.
What MBRWizard Can Do

- Repair the Master Boot Record: Fixes corrupted or overwritten MBR data that prevents Windows from booting.
- Backup and Restore MBR: Allows users to save a copy of the MBR and restore it later if problems occur.
