1. Boot sector restoration tool (Bootsect.exe) updates the master boot code for hard disk partitions in order to switch between BOOTMGR and NTLDR. You can use this tool to restore the boot sector on your computer.
2. Ключи команды bootsect:
bootsect {/help:/nt60:/nt52} {SYS:ALL::} [/force] [/mbr]
– /nt52
– Applies the master boot code that is compatible with NTLDR to SYS, ALL or . The operating system installed on SYS, ALL or must be older than Windows Vista;
– /nt60
– Applies the master boot code that is compatible with BOOTMGR to SYS, ALL or . The operating system installed on SYS, ALL or must be Windows Vista or WindowsServer "Longhorn";
– SYS
– Updates the master boot code on the system partition used to boot Windows;
– ALL
– Updates the master boot code on all partitions. ALL does not necessarily update the boot code for each volume. Instead, this option updates the boot code for on volumes that could be used as Windows boot volumes, which exludes any dinamic volumes that are not connected with an underlying disk partition. This restriction is present because boot code must be located at the beginning of a disk partition;
– Updates the master boot code on the volume associated with this drive letter. Boot code will not be updated if either 1) is not associated with a volume or 2) is associated with a volume not connected to an underlying disk partition;
– /force
– Forcibly dismounts the volume during the boot code update. You should use this option with caution;
– /mbr
– Updates the Master Boot Record without changing the partition specified by SYS, ALL, or drive letter. When used with /nt52 option, the master boot record is compatible with operating system older than Windows Vista. When used with the /nt60 option, the master boot record is compatible with Windows Vista, Windows Server 2008 or later.
