Rebuild MBR with Qiling Disk Master

Overview of Rebuild MBR

How to Rebuild MBR

Before you do

• Download and install the Qiling Disk Master first.
• If your computer won't boot, create a WinPE bootable CD on a working computer using Qiling Disk Master, then use the CD to boot into WinPE and rebuild the MBR.
• If your computer can't boot due to a corrupted MBR, you can try rebuilding it by plugging the problematic disk into another machine or a friend's computer, running Qiling Disk Master, and then using the software to Rebuild MBR on the disk.

How to Rebuild MBR with Partition Assistant

Conclusion

By following the steps above, you can easily rebuild MBR of a system drive, which may resolve boot issues caused by corrupted MBR.

This feature is primarily used to resolve system boot failure issues, such as a "system missing" or "operating system not found" error message, or a black screen with a blinking cursor. It can be particularly helpful when other types of boot failures are difficult to fix.

Notes:

• Rebuild corrupted MBR can only fix issues where the MBR code itself has been damaged. However, it is not capable of resolving problems where the operating system is unbootable due to missing bootable files or system files. In such cases, other solutions are required.
• Rebuilding the Master Boot Record (MBR) is a safe operation that won't result in data loss. However, if done incorrectly on a corrupted MBR, it might render your computer unbootable. It's recommended to learn more about the process before attempting it or backing up your data and disk first.
• Qiling Disk Master Standard version also supports "Rebuild MBR" feature.

FAQs:

Q: No, it's not necessary to use the "Rebuild MBR" feature on a GPT drive. GPT (GUID Partition Table) is a newer partition table scheme that doesn't require an MBR (Master Boot Record) to function.

A: The "Rebuild MBR" tool is mainly used for Master Boot Record (MBR) drives, and it is not necessary if the drive is a GPT drive.

Q: The "Rebuild MBR" tool can be used when you encounter a boot error in the following conditions: The boot sector (MBR) is damaged or corrupted, preventing the computer from booting normally. The tool can be used to create a new MBR, allowing the computer to boot again.

A: This tool is primarily used to resolve system boot failures with error messages such as "system missing", "operating system not found", or a black screen with a blinking cursor. However, in some instances, it may not be effective, and alternative professional repair tools may be necessary to fix the boot issue.

Q: If your PC can't boot without installing the program, you might need to create a bootable USB drive or CD/DVD with the program on it, and then boot from that instead of your internal hard drive. This will allow you to install the program and potentially use the feature you're interested in.

A: You can create a bootable media on another working PC with Partition Assistant installed and boot your PC into WinPE to use the "Rebuild MBR" tool, or unplug your system drive and connect it to another working computer to rebuild MBR.
