BCDEdit /deletevalue

The BCDEdit /deletevalue command deletes or removes a boot entry option (and its value) from the Windows boot configuration data store (BCD). Use the BCDEdit /deletevalue command to remove options that were added using the BCDEdit /set command.

Before deleting BCDEdit options you might need to disable or suspend BitLocker and Secure Boot on the computer.

To delete a boot option value that you have set, use the BCDEdit /deletevalue command. A common scenario for using the BCDEdit /deletevalue command is to remove boot entry options when you are testing and debugging a driver.

For example, if you use BCDEdit /set to change the groupsize processor group option to a new value for testing purposes, you can use BCDEdit /deletevalue to delete the new value and revert to the default value by typing the following command. Note that you must then restart the computer for the change to take effect.

bcdedit /deletevalue groupsize
