发一段健壮的MBR记录（与fdisk的MBR功能相同，但更健壮！） - 无忧启动论坛

bootsect不能改写MBR
只能改写PBR (partition boot record）
和本主题无关
和MBR更是无关
PRB是和分区相关的，所以运行PBR的工具时，一般都需要指定盘符，例如C D E之类的
而运行MBR的工具时，只 ...

C:\Documents and Settings\Administrator>bootsect /mbr

bootsect {/help|/nt60|/nt52} {SYS|ALL|<DriveLetter>:} [/force]

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.

Run "bootsect /help" for detailed usage instructions.

C:\Documents and Settings\Administrator>bootsect /?

bootsect {/help|/nt60|/nt52} {SYS|ALL|<DriveLetter>:} [/force]

Boot sector restoration tool

Bootsect.exe updates the master boot code for hard disk partitions in order to

C:\Documents and Settings\Administrator>bootsect /help

bootsect {/help|/nt60|/nt52} {SYS|ALL|<DriveLetter>:} [/force]

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.

/help Displays these usage instructions.

/nt52 Applies the master boot code that is compatible with NTLDR to SYS,
      ALL, or <DriveLetter>.  The operating system installed on SYS, ALL, or
      <DriveLetter> must be older than Windows Vista.

/nt60 Applies the master boot code that is compatible with BOOTMGR to SYS,
      ALL, or <DriveLetter>.  The operating system installed on SYS, ALL, or
      <DriveLetter> 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 on volumes that could be used as Windows
      boot volumes, which excludes any dynamic 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.

<DriveLetter> Updates the master boot code on the volume associated with this
      drive letter.  Boot code will not be updated if either 1)
      <DriveLetter> is not associated with a volume or 2) <DriveLetter> is
      associated with a volume not connected to an underlying disk
      partition.

/force  Forcibly dismounts the volume(s) during the boot code update.  You
      should use this option with caution.

      If Bootsect.exe cannot gain exclusive volume access then the file
      system may overwrite the boot code before the next reboot.
      Bootsect.exe always attempts to lock and dismount the volume before
      each update.  When /force is specified, a forced dismount is attempted
      if the initial lock attempt fails.  A lock can fail, for example, if
      files on the target volume are currently opened by other programs.

      When successful, a forced dismount allows exclusive volume access and
      a reliable boot code update even though the initial lock failed.  At
      the same time, a forced dismount invalidates all open handles to files
      on the target volume.  This could result in unexpected behavior from
      the programs that opened these files.  Therefore, you should use this
      option with caution.

Example:

To apply the master boot code that is compatible with NTLDR to the volume
labeled E:, use the following command:

bootsect /nt52 E:

win7带的bootsect就带/mbr参数了

和vista的
bootrec /fixmrb 有什么区别？
顺便问一下 32 64位弄出来的ntfs mbr和引导扇有没有区别

　就用这个

直接写入硬盘可用吗？有点不敢哦

目前用这种方式貌似还没有遇到启不动的电脑

量产成本地盘，用HP工具格式化，用UE或者DSPTW或者winhex改写MBR 用本文中的替换，用SYSLINUX.EXE写入分区引导记录。 ...
