Recovery Console Command - Fifteen
Fixmbr
Writes a new master boot record to the hard disk. The fixmbr command can only be used when using the Windows 2000 Recovery Console. The Windows 2000 Recovery Console can be started from the Windows installation program.

fixmbr

Parameters

device_name

The device (drive) to which the new master boot record is to be written. The device name can be obtained from the output of the map command. For example, the device name:

\Device\HardDisk0

Example

The following command example writes a new master boot record to the specified device:

fixmbr \Device\HardDisk0

Note

If device_name is not specified, the new master boot record will be written to the boot device, that is, the drive that loads the main system.
If the system detects an invalid or non-standard partition table mark, the user will be prompted whether to continue executing the command. Do not proceed unless you are accessing a problematic drive. Writing a new master boot record to the system partition may damage the partition table and make the partition inaccessible.
