Hack #48. Fix the Master Boot Record on NTFS Partitions

FIXMBR is available only through the Recovery Console feature of Windows NT, 2000,

FIXMBRcommand followed by the name of the disk partition to be "fixed." For example (press Enter after the command):fixmbr \Device\HardDisk0Type
exitto leave the Recovery Console and restart the system.
Warning
Do not use this method to repair a primary active boot partition that uses GRUB or LILO boot managers [Hack #50] . ...
