Some users get an error saying Master Boot Record of this hard drive is damaged after starting up their computer or just a reboot. And then, they cannot boot up Windows 7 normally.
The MBR in this error is not the partition style like GPT. How much do you know about this Master Boot Record (MBR) of the hard drive in your Windows 7?
MBR is an important data structure on the first sector of the disk that is necessary for system booting. It contains the Partition Table for the disk and a small amount of executable code for the boot start. As a result, a system will not load when the MBR is damaged or missing.
Some other similar bootup errors would be Operating System not found, Missing Operating System, Invalid partition table, and Non-system disk or disk error. Then, how do you fix these errors in Windows 7?
Chances are that you’ll get a way to fix MBR using the Bootrec.exe program with the help of the Windows installation DVD if you search online. It says getting into the Command Prompt and typing “bootrec.exe /fixmbr” will help you repair corrupted MBR.
That is indeed a feasible way. Nevertheless, what if you encounter the error Bootrec.exe Element Not Found? What if you don’t have an installation DVD or system repair disc in hand? The computer may have been used for ages and you cannot remember the location of the installation DVD. You may get the PC from someone else and the installation disc did not come with it.
