What is MBR in Windows 7? Why do you need to restore boot in Windows 7?
A MBR or Master Boot Record is the 512 byte boot sector which is the first sector of a partitioned data storage device such as a hard disk drive. The MBR is actually a small program which is executed when the system boots up. The MBR resides in the first sector of the system hard disk drive. It begins the boot up process in your system by looking up the partition table for determining which partition to be used for booting the system. After looking for the partition, the program transfers control over to the boot sector of the PC which continues the boot up process. You can create the MBR in DOS as well as Windows systems with FDISK or MBR command.

Cause of corruptions in MBR
MBR in Windows 7 can get corrupt sometimes. It usually takes place as you install another operating system over the current operating system. With this, the system can get an error message showing “Operating System Not Found”. If you use the hard disk drive partition without technical knowledge, then the operating system MBR might get corrupt. Another cause for corruption in Windows 7 MBR can include dual booting.
Need to restore MBR
There can be many reasons for corruptions in MBR of Windows 7. You will have the FDISK Command Prompt Console which can help you in resolving the issues. FDISK is included for operating system like Windows 95, Windows 98 and Windows ME. But, FDISK is not distributed to newer operating systems like Windows NT, Windows 2000, Windows XP, Windows Vista and Windows 7.
Most new systems allow booting from DVDs without the need of changing boot order with just clicking on any key when you are prompted to do so. The next step is to select default language, time and keyboard input on the first window and then click the ‘Next’ button. You will then have three options from which you need to select “Repair Your Computer” to get access to the System Recovery window. Then you will be able to choose Command Prompt and turn on the bootsect.exe to change your directory to boot. Now you need to run the bootsect/nt60 SYS: and you can repair the system partition or all partitions.
