When your computer first boots up, your hard drive initializes by accessing its master boot record or master boot record MBR. The place where this information is stored is called the master boot record (MBR). It is also sometimes called the master boot sector or even just the boot sector. The Master Boot Record (MBR) is the information in the first sector of any hard disk or diskette that identifies how and where an operating system is located so that it can be boot (loaded) into the computer's main storage or random access memory. The MBR contains information on the size and specifications of your hard drive's partitions. If your MBR becomes corrupted, then your computer will not be able to identify your hard drive, and it will not be possible to access any information on the drive or initiate your operating system. To avoid data loss, you can create a backup of your MBR. Although Windows 7 does not include native MBR backup capability, you can complete this task using MBRtool, a free utility. If you find some difficulties while performing any of the below mentioned steps on your own, then you can also take help from online technical support at their Toll Free No +1-877-452-9201 For US/CA.
