將 GUID 磁碟分割表格 (GPT) 磁碟變更為主開機記錄 (MBR) 磁碟Change a GUID Partition Table (GPT) disk into a Master Boot Record (MBR) disk

適用於:Windows 10、Windows 8.1、Windows Server (半年度管道)、Windows Server 2016、Windows Server 2012 R2、Windows Server 2012Applies To: Windows 10, Windows 8.1, Windows Server (Semi-Annual Channel), Windows Server 2016, Windows Server 2012 R2, Windows Server 2012

主開機記錄 (MBR) 磁碟使用標準 BIOS 磁碟分割表格。Master Boot Record (MBR) disks use the standard BIOS partition table. GUID 磁碟分割表格 (GPT) 磁碟則使用整合可延伸韌體介面 (UEFI)。GUID Partition Table (GPT) disks use Unified Extensible Firmware Interface (UEFI). MBR 磁碟無法在個別磁碟上支援四個以上的磁碟分割。MBR disks do not support more than four partitions on each disk. 不建議容量大於兩個 TB 的磁碟使用 MBR 磁碟分割方法。The MBR partition method is not recommended for disks larger than two terabytes (TB).

只要磁碟是空的且未包含任何磁碟區,就可以將磁碟從 GPT 變更為 MBR 磁碟分割樣式。You can change a disk from a GPT to an MBR partition style as long as the disk is empty and contains no volumes.

注意

轉換磁碟之前,請先關閉任何正在這些磁碟上執行的程式。Before you convert disks, close any programs that are running on those disks.

注意

您必須至少是備份操作員系統管理員群組的成員,才能完成這些步驟。You must be a member of the Backup Operators or Administrators group, at minimum, to complete these steps.

若要使用 Windows 介面將 GPT 磁碟變更成 MBR 磁碟:To change a GPT disk into an MBR disk using the Windows interface:

  1. 備份或移動您要轉換成 MBR 磁碟的基本 GPT 磁碟上的所有磁碟區。Back up or move all volumes on the basic GPT disk you want to convert into an MBR disk.

  2. 如果磁碟包含任何磁碟分割或磁碟區,請個別按右鍵,然後按一下 [刪除磁碟區]If the disk contains any partitions or volumes, right-click each and then click Delete Volume.

  3. 以滑鼠右鍵按一下要變更成 MBR 磁碟的 GPT 磁碟,然後按一下 [轉換成 MBR 磁碟]Right-click the GPT disk that you want to change into an MBR disk, and then click Convert to MBR disk.

    若要使用命令列將 GPT 磁碟變更成 MBR 磁碟To change a GPT disk into an MBR disk using a command line

  4. 備份或移動您要轉換成 MBR 磁碟的基本 GPT 磁碟上的所有磁碟區。Back up or move all volumes on the basic GPT disk you want to convert into an MBR disk.

  5. 開啟提升權限的命令提示字元,方式為:以滑鼠右鍵按一下 [命令提示字元],然後選擇 [以系統管理員身分執行]Open an elevated command prompt by right-clicking Command Prompt and then choosing Run as Administrator.

  6. 輸入 diskpartType diskpart. 如果磁碟未包含任何磁碟分割或磁碟區,請跳至步驟 6。If the disk contains no partitions or volumes, skip to step 6.

  7. DISKPART 提示中輸入 list diskAt the DISKPART prompt, type list disk. 記下您要刪除的磁碟編號。Note the disk number that you want to delete.

  8. DISKPART 提示中輸入 select disk <disknumber>At the DISKPART prompt, type select disk <disknumber>.

  9. DISKPART 提示中輸入 cleanAt the DISKPART prompt, type clean.

重要

執行 clean 命令將會刪除磁碟上的所有磁碟分割或磁碟區。Running the clean command will delete all partitions or volumes on the disk.

  1. DISKPART 提示中輸入 convert mbrAt the DISKPART prompt, type convert mbr.


Value 描述Description

list disklist disk

顯示磁碟的清單和這些磁碟的相關資訊,例如大小、可用空間數量、磁碟是基本還是動態磁碟,以及磁碟使用的是主開機記錄 (MBR) 還是 GUID 磁碟分割表格 (GPT) 磁碟分割樣式。Displays a list of disks and information about them, such as their size, the amount of available free space, whether the disk is a Basic or Dynamic disk, and whether the disk uses the Master Boot Record (MBR) or GUID Partition Table (GPT) partition style. 標示有星號 () 的磁碟具有焦點。The disk marked with an asterisk () has focus.

select diskselect disk

選取指定的磁碟 (其中 disknumber 是磁碟編號),並讓它成為焦點。Selects the specified disk, where disknumber is the disk number, and gives it focus.

convert mbrconvert mbr

將使用 GUID 磁碟分割表格 (GPT) 磁碟分割樣式的空白基本磁碟轉換為使用主開機記錄 (MBR) 磁碟分割樣式的基本磁碟。Converts an empty basic disk with the GUID Partition Table (GPT) partition style to a basic disk with the Master Boot Record (MBR) partition style.
