BCDEdit Operation on entries in a store

BCDEdit /copy

This command creates a copy of the specified boot entry.

Syntax

bcdedit [/store <filename>] /copy {<id>} /d <description>

Parameter

Example

The following command creates a copy of the specified operating system boot entry: bcdedit /copy {cbd971bf-b7b8-4885-951a-fa03044f5d71} /d "Copy of entry"

BCDEdit /create

This command creates a new entry in the boot configuration data store. If a well-known identifier is specified, then the /application, /inherit and /device options cannot be specified. If the <id> is not specified, or if <id> is not well-known, then you must specify an /application, /inherit or /device option.

Syntax

bcdedit /create [{<id>}] [/d <description>] [/application <apptype> | /inherit [<apptype>] | /inherit DEVICE | /device]

Parameter

<id> Specifies the identifier to be used for the new entry. For more information about identifiers, run "bcdedit /? ID". <description>Specifies the description to be applied to the new entry. /application <apptype>Specifies that the new entry must be an application entry. <apptype> specifies the application type. <apptype> can be one of the following: ~~BOOTAPPBOOTSECTOROSLOADERRESUMESTARTUP~~ If you use other application types instead of one of these, you must also specify a well-known identifier. /inherit [<apptype>]Specifies that the new entry must be an inherit entry, and <apptype> specifies the application type. If <apptype> is not specified, then the entry can be inherited by any entry. If specified, <apptype> can be one of the following: ~~BOOTMGRBOOTSECTORFWBOOTMGRMEMDIAGNTLDROSLOADERRESUME~~ The modifier prevents the inherit entry from being inherited by an application entry of <apptype>. /inherit DEVICESpecifies that the new entry must be an inherit entry, and that the entry can only be inherited by a device options entry. /deviceSpecifies that the new entry must be an additional device options entry.

Example

The following command creates a NTLDR based OS loader entry (Ntldr): bcdedit /create {ntldr} /d "Earlier Windows OS Loader" The following command creates a RAM disk additional options entry: bcdedit /create {ramdiskoptions} The following command creates a new operating system boot entry: bcdedit /create /d "Windows Vista" /application osloader The following command creates a new debugger settings entry: bcdedit /create {dbgsettings}

BCDEdit /delete

This command deletes an entry from the boot configuration data store.

Syntax

bcdedit [/store <filename>] /delete <id> [/f] [/cleanup | /nocleanup]

Parameter

<filename> Specifies the store to be used. If this option is not specified, the system store is used. For more information, run "bcdedit /? store". <id>Specifies the identifier of the boot entry that you want to delete. For more information about identifiers, run "bcdedit /? ID". /fDeletes the specified entry. Without this option, Bcdedit will not delete any entries that have a well-known identifier. /cleanupDeletes the specified entry and removes the entry from the display order. Any other references to the entry being deleted will also be removed from the store. When deleting an OS loader entry, the associated resume from hibernation entry is also deleted if it is not referenced by any other OS loaders. This option is assumed unless /nocleanup is specified. /nocleanupDeletes the specified entry without removing the entry from the display order.

Example

The following command deletes the specified operating system entry from the store and removes the entry from the display order: bcdedit /delete {cbd971bf-b7b8-4885-951a-fa03044f5d71} The following command deletes the specified operating system entry from the store and removes the entry from the display order: bcdedit /delete {cbd971bf-b7b8-4885-951a-fa03044f5d71} /cleanup The following command deletes the specified operating system entry from the store without removing the entry from the display order: bcdedit /delete {cbd971bf-b7b8-4885-951a-fa03044f5d71} /nocleanup The following command deletes the NTLDR based OS loader entry from the store: bcdedit /delete {ntldr} /f
