• Corrupted system files: If important boot files are missing or damaged, preventing Windows from loading.
• BCD errors: Issues with Boot Configuration Data can stop the system from starting.
• Black screen after login or update: When Windows loads improperly due to failed updates or driver issues.
• Disk or partition problems: Errors in the system partition can block the boot process.
• Virus or malware attacks: Malicious programs may damage boot files or system settings.
• Hardware changes: Replacing a hard drive or SSD may require boot repair to restore system access.

In these cases, a bootable USB lets you access repair options like Startup Repair, Command Prompt, or system restore, helping you fix the issue quickly and safely.

Rebuilding the MBR (Master Boot Record) is necessary when the boot sector is damaged or missing, which prevents Windows from loading properly. Below are common cases where you may need to rebuild the MBR:

• “Operating System not found” error: The system cannot locate the OS due to a broken or missing MBR.
• “Missing operating system” message: Often appears when the boot record is corrupted.
• “Invalid partition table” error: Indicates incorrect or damaged partition information in the MBR.

• System crash or sudden power failure: Can corrupt boot-related data, including the MBR.

In these situations, rebuilding the MBR using recovery tools or a bootable USB can restore the boot structure and allow Windows to start normally again.

Step 1. Connect the Windows 10 repair bootable USB and power on your PC. When the manufacturer’s logo appears, press the appropriate key to enter the BIOS setup.

Step 2. Navigate to the Boot tab and set the bootable media as the first boot device. Save your changes and restart the computer.
