When do you need to fix the MBR?

MBR (Master Boot Record) is the most important sector of the drive and located at the beginning of the drive that identifies the OS location and allows OS to boot successfully. It informs the boot process as to what is about to follow, such as partition layouts, sizes, file systems, and more. Briefly, MBR decides if the Windows can boot up smoothly.

Therefore, when your system fails to boot into Windows and is stuck with a screen with various error messages reporting “Missing operating system,” “MBR error,” “Error loading operating system,” “Invalid partition table,” or similar, there is a very strong chance that the MBR is damaged for some reasons and needs to be repaired.

GParted is a free partition editor for graphically managing your disk partitions. It can be used on x86 and x86-64 based computers running Linux, Windows, or Mac OS X by booting from media containing GParted Live. It allows you to can create, delete, resize, move, copy partition and so on.

Then, you might wonder if you can use GParted to fix MBR in Windows PC. As a matter of fact, GParted does not have the feature to fix MBR. But the GParted Live can help you make a bootable media for booting your computer and using TestDisk to fix Windows MBR.

Note: GParted is the partition editor application. GParted Live is a small bootable GNU/Linux distribution that contains the free partition editor application.

Tutorial: Use GParted Live to fix MBR in Windows 10, 8, 7

First of all, please download the GParted Live. There will be 2 versions for your selection. For 32-bit system, choose the i686.iso version. For a 64-bit system, download the amd64.iso one.

Secondly, write the disc image to a bootable device (a USB flash drive, a CD, or a DVD). For this task, you can use Tuxboot to install GParted Live on your USB flash drive. Download the tuxboot file. Run the exe file, select an ISO file or a distribution to download, select a target drive (USB Drive or Hard Disk), then reboot once done.

Thirdly, insert the bootable GParted Live media into the system with a corrupt MBR. Power on the machine and press the appropriate button (usually F1, F2, F8, F9, F12, ESC, or backspace) during the OS initiation to get to the BIOS boot menu and change the startup order to boot USB by default.

Boot computer from the GParted Live media. Make a few selections, such as the language and operational mode. Then follow the steps to learn how GParted Live fix MBR in Windows PC.

Step 1. Once the GParted Live environment loads, open a Terminal window by double clicking on the terminal icon on the desktop, type “sudo fdisk –l” and press Enter to list all drives and partitions available on your system now.

Step 2. Open a new Terminal window, type “testdisk”, then select “No Log”.

Step 3. Select the disk with corrupted MBR, then “Proceed”.

If the system still won’t boot, you can try to repair the boot sector of the boot partition.

1. Start testdisk again, select the “No log” option and select your Disk where Windows is installed. Do the same steps as above. Choose “[Advanced] Filesystem Utils”.

2. Then select the boot partition and choose [boot] Boot sector Recover. Following by option “[Rebuild BS] Rebuild boot sector”.

This will write the new sector to disk. From the steps, we can know that it is not GParted, but the TestDisk that fixes MBR. The GParted Live can just be regarded as an assistant tool.
