MBR stands for Master Boot Record. As stated in Wikipedia the MBR is ” the 512-byte boot sector that is the first sector (“LBA Sector 0″) of a partitioned data storage device such as a hard disk”. Basically, it is the first sector of your hard disk used by the BIOS to detect the operating systems installed in your computer (see how important it is?). If such a sector is corrupted, while booting up the computer you could get weird errors such as: “Operating System Not Found” or “Missing operating system”. Here is a brief tutorial on what to do to fix and restore it.

1. Insert your Windows 7 installation DVD in DVD drive.
2. Restart your computer and boot from your DVD drive (to do this you firstly need to go to your BIOS and set your PC to bootup from the DVD drive).
3. When asked, boot from the DVD by pressing  F10 or any key on your keyboard.
4. Now, check your Language, Time,  and Keyboard Input in the proper section and press the Next button.
5. Now click on Repair Your Computer to gain access to the System Recovery window.
6. Click Command Prompt.
7. Type one of these following commands and hit Enter:

• bootsect /nt60 C:\ (to type if your operating system is installed in C:   Of course you can change C: with the word of the partition where your OS is installed)
• bootsect /nt60 SYS (to use if the first command doesn’t work)
• bootsect /nt60 ALL (to use if the above commands do not work)
• Once done, eject the disc and restart your computer for the change to take effect.
