How Do I Fix the Master Boot Record (MBR)?

For versions of Windows prior to Win 7 our standard advice was to run fdisk /mbr and then re-image the device. However, I believe that fdisk is not included with Windows 7.

fdisk 是一個指令行應用程式，用於在 Linux 中管理磁碟磁區。 讓您可以建立、刪除和調整磁碟區大小以及設定各種磁碟區屬性。

首先概述了Fdisk_mbr的重要性和理论基础，阐述了MBR的工作原理和磁盘分区类型，以及Fdisk_mbr的核心功能。 接着，详细介绍了使用Fdisk_mbr创建和管理磁盘分区、修复MBR和重建分区表的步骤与技巧。

MBR is an essential part of booting the computer. However, if the MBR of Windows is damaged, what you need do is to fix MBR. And then how can you rebuild MBR with ease? This post shows you how to fix MBR with the step-by-step guide.

fdisk可以寫入支援最多四個分割區的 MBR。 另外三個分割區用於其他作業系統，例如 CP/M-86 和 Xenix，這些作業系統有它們自己的分割區工具。
