Using the Recovery Console to Replace the MBR
You can use the fixmbr command in Recovery Console to rewrite the MBR to
resolve a corrupted MBR on a startup disk. However, running fixmbr
overwrites only the master boot code, leaving the existing partition table
intact. If the corruption in the MBR affects the partition table, running
fixmbr might not resolve the problem.
Caution
Use this command with care because it can damage your partition table if any
of the following apply:
A virus is present and a third-party operating system is installed on the
same computer.
A nonstandard MBR is installed by a third-party disk utility.
A hardware problem exists.
It is recommended that you run antivirus software before you use the fixmbr
command.
