How to repair Windows 7 MBR

Sometimes you can corrupt Windows’ MBR (Master Boot Record) unintentionally, through installation of another operating system for instance, and you need to repair it before Windows can boot again. The error message that you usually get is “Operating System not found”
How to repair
1. Insert Win 7 installation DVD and boot from DVD drive. While in some older systems you may have to change boot order through system BIOS, most newer systems allow booting from DVD without changing boot order by simply clicking on any key when prompted to doing so.
2. Choose your default “Language”, “Time”, and “keyboard Input” on the first window and click next
3. Click on “Repair Your Computer” to gain access to the System Recovery window.
4. Now choose “Command Prompt” in order to run the desired utility which is called “bootsect.exe“. Bootsect is located inside the boot folder so change your directory to boot. Now run “bootsect /nt60 C:\” if you had Win 7 initially installed in the C partition. Alternatively, you can run “bootsect /nt60 SYS” or “bootsect /nt60 ALL” to repair the system partition or all partitions. Eject the DVD, and restart computer. Your computer should now boot Win 7 again.
