對存儲進行操作的命令

/createstore	該命令創建了一個新的空引導配置數據存儲。創建的存儲不是系統存儲。 bcdedit /createstore 指定引導配置數據存儲區的文件名。如果文件名包含空格，則必須用引號括起來""。例子: 下面的命令創建指定的存儲文件: bcdedit /createstore C:\DATA\BCD
/export	該命令將系統存儲的內容導出到一個文件中。稍后可以使用此文件恢復系統存儲的狀態。此命令僅對系統存儲有效。要用作導出目標的文件名。如果文件名包含空格，則必須用引號括起來""。例子: 下面的命令將系統存儲導出到指定的文件: bcdedit /export "C:\Data\BCD Backup"
/import	此命令使用以前使用/export命令生成的備份數據文件恢復系統存儲的狀態。在進行導入之前，系統存儲中的任何現有條目都會被刪除。此命令僅對系統存儲有效。 bcdedit /import[/clean] 導入到系統存儲區的文件的名稱。如果文件名包含空格，則必須用引號括起來""。 clean指定應該刪除所有現有固件引導條目(只影響EFI系統)。例子: 以下命令將指定的文件導入系統存儲區。 bcdedit /import "C:\Data\BCD Backup" /clean
/sysstore	此命令設置系統存儲設備。此命令僅在系統存儲設備不明確的情況下對EFI系統有效。此設置在重新引導時不會持久存在。 bcdedit /sysstore 要設置為系統存儲設備的系統分區的名稱。該設備必須是一個系統分區。例子: 以下命令將系統存儲設備設置為指定: bcdedit /sysstore C:

以下命令將當前操作系統引導項的NX策略設置為OptIn。

bcdedit /set nx optin

控制輸出的命令

/enum

此命令列出存儲中的條目。/enum命令是默認命令，因此運行不帶參數的“ bcdedit”等效于運行“ bcdedit / enum ACTIVE”。

bcdedit [/store] /enum [|] [/v]

指定要使用的存儲。如果未指定此選項，則使用系統存儲。有關更多信息，請運行“ bcdedit /？store”。

指定要列出的條目的類型。可以是以下之一：

ACTIVE -引導管理器中的所有條目默認顯示順序。

FIRMWARE -所有固件應用程序。

BOOTAPP-所有引導環境應用程序。

BOOTMGR-引導管理器。

OSLOADER-所有操作系統條目。

RESUME -所有從休眠條目恢復。

INHERIT -所有繼承條目。

ALL-全部輸入。

指定要列出的條目的標識符。如果提供了標識符，則僅列出指定的對象。有關標識符的信息，請運行“ bcdedit /？ID”。

/v顯示完整的條目標識符，而不是使用名稱作為知名標識符。

例子：

以下命令列出了所有操作系統加載程序引導項：

bcdedit /enum OSLOADER

以下命令列出了所有引導管理器條目：

bcdedit /enum BOOTMGR

以下命令僅列出默認的引導項：

bcdedit /enum {default}

以下命令僅列出指定的操作系統引導項：

bcdedit /enum {b38a9fc1-5690-11da-b795-e9ad3c5e0e3a}

命令行選項，它完整顯示條目標識符，而不是使用名稱作為知名標識符。

單獨使用/v作為命令，以完整顯示ACTIVE類型的條目標識符。

通常，任何眾所周知的條目標識符都將用其友好的速記形式代替。將/v指定為命令行開關可防止此替換，并完整顯示所有標識符。單獨運行“ bcdedit /v”等效于運行“ bcdedit / enum ACTIVE /v”。

bcdedit /v

例：

以下命令列出了系統存儲中的活動條目，并完整顯示了所有條目標識符。

bcdedit /enum ACTIVE /v

控制引導管理器的命令

The created store is not a system store. bcdedit /createstore specifies the file name of the boot configuration data store. If the file name contains spaces, it must be enclosed in quotation marks (""). Example: The following command creates the specified store file: bcdedit /createstore C:\DATA\BCD
/export	This command exports the contents of the system store into a file. This file can be used later to restore the state of the system store. This command is only valid for the system store. is the file name to be used as the destination for the export. If the file name contains spaces, it must be enclosed in quotation marks (""). Example: The following command exports the system store to the specified file: bcdedit /export "C:\Data\BCD Backup"
/import	This command restores the state of the system store using a backup data file previously generated using the /export command. Any existing entries in the system store are deleted before the import takes place. This command is only valid for the system store. bcdedit /import[/clean] the name of the file that is imported into the system store. If the file name contains spaces, it must be enclosed in quotation marks (""). /clean specifies that all existing firmware boot entries should be deleted (only affects EFI systems). Example: The following command imports the specified file into the system store. bcdedit /import "C:\Data\BCD Backup" /clean

specifies the value that should be assigned to the option. The format ofdepends on the data type specified. Run "bcdedit /? FORMATS" for more information about data formats.

/addfirst - This switch can only be used if datatype is an object list. Adds the specified entry identifier to the top of the list. If this switch is specified, only a single entry identifier may be specified. If the specified identifier is already in the list, it is moved to the top of the list.

/addlast - This switch can only be used if datatype is an object list. Adds the specified entry identifier to the end of the list. If this switch is specified, only a single entry identifier may be specified. If the specified identifier is already in the list, it is moved to the end of the list.

/remove - This switch can only be used if datatype is an object list. Removes the specified entry identifier from the list. If this switch is specified, only a single entry identifier may be specified. If the identifier is not in the list, then the operation has no effect. If the last entry is being removed, then the datatype value is deleted.

Examples:

The following command sets the application device to the partition C: for the specified operating system entry:

bcdedit /set {cbd971bf-b7b8-4885-951a-fa03044f5d71} device partition=C:

NOTE: Use 'hd_partiton=' syntax to explicitly disable automatic VHD detection, and create entries that are compatible for booting a virtual machine, for example:

bcdedit /store F:\boot\bcd /set {default} device hd_partition=F:

The following command sets the OS device to a VHD file (C:\vdisks\vdisk01.vhd) for the specified operating system entry:

bcdedit /set {cbd971bf-b7b8-4885-951a-fa03044f5d71} osdevice vhd=[C:]\vdisks\disk01.vhd

The following command sets the NX policy to OptIn for the current operating system boot entry.

bcdedit /set nx optin

Commands that control output

/enum

This command lists entries in a store. The /enum command is the default, so running "bcdedit" without parameters is equivalent to running "bcdedit /enum ACTIVE".

bcdedit [/store] /enum [|] [/v]

specifies the store to be used. If this option is not specified, the system store is used. For more information, run "bcdedit /? store".

specifies the type of entries to be listed.can be one of the following:

ACTIVE - All entries in the boot manager display order by default.

FIRMWARE - All firmware applications.

BOOTAPP - All boot environment applications.

BOOTMGR - The boot manager.

OSLOADER - All operating system entries.

RESUME - All resume from hibernation entries.

INHERIT - All inherit entries.

ALL - Do all entries.

specifies the identifier of the entry to be listed. If an identifier is provided, then only the specified object will be listed. For information about identifiers, run "bcdedit /? ID".

/v Displays entry identifiers in full, rather than using names for well-known identifiers.

Examples:

The following command lists all operating system loader boot entries:

bcdedit /enum OSLOADER

The following command lists all boot manager entries:

bcdedit /enum BOOTMGR

The following command lists only the default boot entry:

bcdedit /enum {default}

The following command lists only the specified operating system boot entry:

bcdedit /enum {b38a9fc1-5690-11da-b795-e9ad3c5e0e3a}

Command line option that displays entry identifiers in full, rather than using names for well-known identifiers.

Use /v by itself as a command to display entry identifiers in full for the ACTIVE type.

Usually, any well-known entry identifiers are replaced by their friendly shorthand form. Specifying /v as a command line switch prevents this replacement and displays all identifiers in full. Running "bcdedit /v" by itself is equivalent to running "bcdedit /enum ACTIVE /v".

bcdedit /v

Example:

The following command lists the active entries in the system store with all entry identifiers displayed in full.

bcdedit /enum ACTIVE /v

Commands that control the boot manager

/bootsequence	This command sets the one-time boot sequence to be used by the boot manager. bcdedit /bootsequence[...] [ /addfirst \| /addlast \| /remove ] [...] specifies a list of identifiers that make up the boot sequence. You must specify at least one identifier and must separate identifiers by spaces. For more information about identifiers, run "bcdedit /? ID". /addfirst - Adds the specified entry identifier to the top of the boot sequence. If this switch is specified, only a single identifier may be specified. If the identifier is already in the list, it is moved to the top of the list. /addlast - Adds the specified entry identifier to the end of the boot sequence. If this switch is specified, only a single identifier may be specified. If the identifier is already in the list, it is moved to the end of the list. /remove - Removes the specified entry identifier from the boot sequence. If this switch is specified, only a single entry identifier may be specified. If the identifier is not in the list, then the operation has no effect. If the last entry is being removed, then the boot sequence value is deleted from the boot manager entry. Examples: The following command sets two OS entries and the NTLDR based OS loader in the boot manager one-time boot sequence: bcdedit /bootsequence {802d5e32-0784-11da-bd33-000476eba25f} {cbd971bf-b7b8-4885-951a-fa03044f5d71} {ntldr} The following command adds the specified OS entry to the end of the boot manager one-time boot sequence: bcdedit /bootsequence {802d5e32-0784-11da-bd33-000476eba25f} /addlast
/default	This command sets the default entry that the boot manager will use when the timeout expires. bcdedit /default specifies the identifier of the boot entry to be used as the default when the time-out expires. For information about identifiers, run "bcdedit /? ID". Examples: The following command sets the specified entry as the default boot manager entry: bcdedit /default {cbd971bf-b7b8-4885-951a-fa03044f5d71} The following command sets the NTLDR based OS loader as the default entry: bcdedit /default {ntldr}
