Rebuild MBR, fix MBR, repair MBR or recover MBR with EaseUS Partition Master to quickly reaccess the system whenever the system fails to boot due to damaged MBR problems under Windows 2000/XP/2003/Vista/2008/2012/ and Windows 7/8/10.

You may never feel strange to those error messages: "Operating System not found" or blank screen without any message when you boot the computer? Sometimes you may corrupt Windows' MBR (Master Boot Record) unintentionally and come with the problem failing to enter the system. In this situation, to rebuild MBR rather than reinstall the Windows will be much more convenient and time-saving.

EaseUS Partition Master has already offered the function to rebuild MBR in the case of boot failure due to MBR problems. Please see the following step-by-step instructions to rebuild MBR.

This rebuild MBR feature can fix master boot code problem, but it can not solve your problem if the Windows Operating System files are corrupted.
