Learn how to edit boot options in Windows to customize how your system starts. This guide shows you how to use BCDEdit, a built-in command-line tool, to modify boot entries, configure operating system features, and safely customize boot parameters.
For more information, see BCDEdit options reference. For information about BCDEdit command syntax, type bcdedit /? or bcdedit /? TOPICS in a Command Prompt window.
Caution
You need administrative privileges to use BCDEdit to modify BCD. Changing some boot entry options by using the BCDEdit /set command could make your computer inoperable. As an alternative, use the System Configuration utility (MSConfig.exe) to change boot settings. For more information, see How to open MSConfig in Windows 10.
Note
Before setting BCDEdit options, you might need to disable or suspend BitLocker and Secure Boot on the computer.
For help on editing boot entry parameters to enable and disable Windows features, see Using boot parameters.
Configure operating system features in boot options
To configure operating system features in boot options:
Add a new boot entry for the operating system by copying an existing boot entry from the same operating system.
Change the friendly name of the newly created boot entry so that you can identify it in the boot menu.
Add parameters to the boot entry that enable and configure Windows features.
To make testing easier, configure these settings:
Make the new boot entry the default entry so it boots automatically.
Change the boot menu time-out:
- Shorten the time-out for quick testing cycles
- Lengthen the time-out when you need time to select entries
