Fix Windows 7 Master Boot Record [MBR] after installing Linux


Repair MBR in Windows 7

First, insert your Windows 7 DVD into your DVD drive and restart your computer. You should get a message asking to press any key to boot from CD.

Note that this message will automatically come up if your boot order is set to CD/DVD drive first. If not, you will not get the message to press any key. In that case, you can read an article on how to change the boot order in the Windows BIOS.

Next, choose the Language, Time and Keyboard and then press Next. Usually, you do not have to change anything here.

On the next screen, you will see a link called Repair your computer at the bottom. Click on that.

System Recovery Options will now search for Windows 7 installations on your computer.

Once it finds it, go ahead and select your operating system and choose Next.

Now you will see the list of System Recovery Options, which include Startup Repair, System Restore, System Image Recovery, Windows Memory Diagnostic, and Command Prompt. In our case, we will choose Command Prompt since we have to run a command to fix the MBR.

At the command prompt, simply type in bootrec.exe /fixmbr and press Enter.

That’s it! Restart your computer and hopefully you will see the Windows logo instead of that horrible “Operating system not found” error message or no windows 7 at all.
