bcdedit
Boot Configuration Data (BCD) files provide a store that is used to describe boot applications and boot application settings. The objects and elements in the store effectively replace Boot.ini.
BCDEdit is a command-line tool for managing BCD stores. It can be used for a variety of purposes, including creating new stores, modifying existing stores, adding boot menu parameters, and so on. BCDEdit serves essentially the same purpose as Bootcfg.exe on earlier versions of Windows, but with two major improvements:
Exposes a wider range of boot parameters than Bootcfg.exe.
Has improved scripting support.
Note
Administrative privileges are required to use BCDEdit to modify BCD.
BCDEdit is the primary tool for editing the boot configuration of Windows Vista and later versions of Windows. It is included with the Windows Vista distribution in the %WINDIR%\System32 folder.
BCDEdit is limited to the standard data types and is designed primarily to perform single common changes to BCD. For more complex operations or nonstandard data types, consider using the BCD Windows Management Instrumentation (WMI) application programming interface (API) to create more powerful and flexible custom tools.
Syntax
bcdedit /command [<argument1>] [<argument2>] ...
Parameters
General BCDEdit Command-Line Options
Option
Description
/?
Displays a list of BCDEdit commands. Running this command without an argument displays a summary of the available commands. To display detailed help for a particular command, run bcdedit /? <command>, where <command> is the name of the command you are searching for more information about. For example, bcdedit /? createstore displays detailed help for the Createstore command.

Parameters that Operate on a Store
Option
Description
/createstore
Creates a new empty boot configuration data store. The created store is not a system store.
/export
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 valid only for the system store.
/import
Restores the state of the system store by using a backup data file previously generated by using the /export option. This command deletes any existing entries in the system store before the import takes place. This command is valid only for the system store.
/store
This option can be used with most BCDedit commands to specify the store to be used. If this option is not specified, then BCDEdit operates on the system store. Running the bcdedit /store command by itself is equivalent to running the bcdedit /enum active command.
Parameters that Operate on Entries in a Store
Parameter
Description
/copy
Makes a copy of a specified boot entry in the same system store.
/create
Creates a new entry in the boot configuration data store. If a well-known identifier is specified, then the /application, /inherit, and /device parameters cannot be specified. If an identifier is not specified or not well known, an /application, /inherit, or /device option must be specified.
/delete
Deletes an element from a specified entry.
Parameters that Operate on Entry Options
Parameter
Description
/deletevalue
