To use BCDEdit, you must be a member of the Administrators group on the computer.A file with EFI file extension is an Extensible Firmware Interface file. To edit boot options in Windows, one option is to use BCDEdit (BCDEdit.exe), a tool included in Windows. For more information about these boot options, see BCD Boot Options Reference. The BCD store, with its object-and-element architecture, uses GUIDs and names such as "Default" to identify boot-related applications.īCD includes its own set of boot options. This feature is can be used for debugging and troubleshooting, especially when a BCD store must be restored while running Startup Repair, from USB-based storage media, or even remotely. You can manage BCD remotely and manage BCD when the system boots from media other than the media on which the BCD store resides. BCD is available at run time and during all phases of system setup. It is more secure than previous boot option storage configurations, and lets Administrators assign rights for managing boot options.

In this configuration, the Windows Boot Manager is generic and unaware of the specific requirements for each operating system while the system-specific boot loaders are optimized for the system that they load. Windows includes boot loader components that are designed to load Windows quickly and securely. For more information, see How to open MSConfig in Windows 10. As an alternative, use the System Configuration utility (MSConfig.exe) to change boot settings. Changing some boot entry options using BCDEdit could render your computer inoperable. Administrative privileges are required to use BCDEdit to modify BCD.
