bcdedit /set nx optin

控制输出的命令

/enum

此命令列出存储中的条目。/enum命令是默认命令，因此运行不带参数的“ bcdedit”等效于运行“ bcdedit / enum ACTIVE”。

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

指定要使用的存储。如果未指定此选项，则使用系统存储。有关更多信息，请运行“ bcdedit /？store”。

指定要列出的条目的类型。可以是以下之一：

ACTIVE -引导管理器中的所有条目默认显示顺序。

FIRMWARE -所有固件应用程序。

BOOTAPP-所有引导环境应用程序。

BOOTMGR-引导管理器。

OSLOADER-所有操作系统条目。

RESUME -所有从休眠条目恢复。

INHERIT -所有继承条目。

ALL-全部输入。

指定要列出的条目的标识符。如果提供了标识符，则仅列出指定的对象。有关标识符的信息，请运行“ bcdedit /？ID”。

/v显示完整的条目标识符，而不是使用名称作为知名标识符。

例子：

以下命令列出了所有操作系统加载程序引导项：

bcdedit /enum OSLOADER

以下命令列出了所有引导管理器条目：

bcdedit /enum BOOTMGR

以下命令仅列出默认的引导项：

bcdedit /enum {default}

以下命令仅列出指定的操作系统引导项：

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

/v

命令行选项，它完整显示条目标识符，而不是使用名称作为知名标识符。

单独使用/v作为命令，以完整显示ACTIVE类型的条目标识符。

通常，任何众所周知的条目标识符都将用其友好的速记形式代替。将/v指定为命令行开关可防止此替换，并完整显示所有标识符。单独运行“ bcdedit /v”等效于运行“ bcdedit / enum ACTIVE /v”。

bcdedit /v

例：

以下命令列出了系统存储中的活动条目，并完整显示了所有条目标识符。

bcdedit /enum ACTIVE /v

/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:

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}

/v

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}
/displayorder	This command sets the display order to be used by the boot manager. bcdedit /displayorder[...] [ /addfirst \| /addlast \| /remove ] [...] specifies a list of identifiers that make up the display order. At least one identifier must be specified and they must be separated by spaces. For more information about identifiers, run "bcdedit /? ID". /addfirst - Adds the specified entry identifier to the top of the display order. 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 - Adds the specified entry identifier to the end of the display order. 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 - Removes the specified entry identifier from the display order. 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 display order 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 display order: bcdedit /displayorder {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 display order: bcdedit /displayorder {802d5e32-0784-11da-bd33-000476eba25f} /addlast
/timeout	This command sets the time to wait, in seconds, before the boot manager selects a default entry.

/toolsdisplayorder	This command will set the display order to be used by the boot manager when displaying the tools menu. bcdedit /toolsdisplayorder[...] [ /addfirst \| /addlast \| /remove ] [...] specifies a list of identifiers that make up the tools display order. At least one identifier must be specified and they must be separated by spaces. For more information about identifiers, run "bcdedit /? ID". /addfirst - Adds the specified entry identifier to the top of the tools display order. 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 - Adds the specified entry identifier to the end of the tools display order. 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 - Removes the specified entry identifier from the tools display order. 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 tools display order value is deleted from the boot manager entry. Examples: The following command sets two tools entries and the memory diagnostic in the boot manager's tools display order: bcdedit /toolsdisplayorder {802d5e32-0784-11da-bd33-000476eba25f} {cbd971bf-b7b8-4885-951a-fa03044f5d71} {memdiag} The following command adds the specified tool entry to the end of the boot manager's tools display order: bcdedit /toolsdisplayorder {802d5e32-0784-11da-bd33-000476eba25f} /addlast
