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
