Understanding MBR Issues


Typical MBR Opening Challenges

GNU GRUB Isn't There

You attempt to load your MBR file and get an error such as "%%os%% Can't Open The MBR File Extension". Customarily, this means that GNU GRUB is not installed on %%os%%. You won't be able to double-click to open your MBR because your OS doesn't know what to do with it.


Tip: If you have another software that you know opens MBR files, you can select it by hitting the "Show Apps" button.


GNU GRUB Requires Update

In other instances, your Master Boot Record File file version may not be supported by your version of GNU GRUB. You will need to download a newer version of GNU GRUB if you don't have the right version. This issue mainly occurs when your Master Boot Record File file was created by a newer version of GNU GRUB than you have on your PC.


Tip: Find clues on the correct software version by right-clicking your MBR file and clicking "Properties".


Primarily, problems experienced when opening MBR files are due to having the incorrect version of GNU GRUB installed on your computer.


Additional MBR Opening Issues

You can still experience errors opening MBR files even with the latest version of GNU GRUB installed on your PC. If you are still having problems opening MBR files, there may be other issues that are preventing you from opening these files. These issues include:

  • Corrupt Windows Registry file path references for MBR
  • Mistaken removal of the Windows registry MBR description
  • Corrupt install of GNU GRUB or other MBR-related program
  • Your MBR file is corrupted (issues with your Master Boot Record File file itself)
  • The MBR is infected with a virus
  • Device drivers of the hardware associated with your MBR file are corrupt or out-of-date
