Quick Tips to Fix Boot Errors in Windows 10

By | January 3, 2022

When your computer won’t boot, it’s easy to panic. Fortunately, if your boot issue is related to the Master Boot Record, as in the case of the “Windows failed to start” message, it’s not that hard to fix.

The MBR is the area on your computer’s hard drive that stores information about the partitions on the disk. It also contains information about how the computer should load the OS. While MBR was an older scheme that was phased out in favor of GPT (GUID Partition Table), many computers still use MBR for backwards compatibility.

Here’s how to fix your MBR related boot issues. This is often caused by corrupted files, and can appear when you double-boot a copy of Linux on your Windows machine.


How to Fix Master Boot Record in Windows 10

  • Since you cannot boot into Windows to access the recovery tools, you will need to create Windows 10 installation media on a removable drive. Take a spare flash drive and follow our instructions to create a Windows 10 disc.
  • Connect the flash drive to your PC and boot from it. Click Next once you see the Windows Settings box, then select the Repair your computer referensi at the bottom left.
  • You will see several recovery options. Select Troubleshoot, then Command Prompt.
  • Now, you have to run one of several commands to repair the MBR. You can reboot after each one and try to start up as usual. Try the following fixes to get started:

bootrec / fixmbr

  • When it’s done, you’ll see a message notifying you.
  • If this command doesn’t fix your problem, you can try the next command to delete the existing MBR and create a new one:

bootrec / fixboot

  • If the above command doesn’t solve the problem, try using the following to repair the Boot Configuration Data:

bootrec / rebuildbcd

  • If you have installed multiple OSes on your computer, run this command to force Windows to check all of them again:

bootrec / scanos

Hopefully, one of the above boot repair commands will solve your MBR problem.
