This option is not set by default, which means test-signed kernel-mode drivers on 64-bit versions of Windows 10, Windows 8.1, Windows 8, Windows 7, Windows Server 2008, and Windows Vista will not load by default.

Cargo truck drivers have been experiencing longer than usual delays at both Tuas and Woodlands checkpoints since last week after Singapore's Ministry of Trade and Industry (MTI) announced that. WASHINGTON (AP) — The Latest on the fallout and increased security efforts after the attack of the U.S. Capitol by pro-Trump loyalists (all times local): 7:30 p.m. Police have arrested a man.

The BCDEdit /set command sets a boot entry option value in the Windows boot configuration data store (BCD). Use the BCDEdit /set command to configure specific boot entry elements, such as kernel debugger settings, memory options, or options that enable test-signed kernel-mode code or load alternate hardware abstraction layer (HAL) and kernel files. To remove a boot entry option, use the BCDEdit /deletevalue command.

Caution

Administrative privileges are required to use BCDEdit to modify BCD. Changing some boot entry options using the BCDEdit /set command could render your computer inoperable. As an alternative, use the System Configuration utility (MSConfig.exe) to change boot settings.

Note

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

Alternatives to BCDEdit

Settings startup options

Tip

To avoid the risk associated with using BCDEdit, consider using an alternative method to perform boot configuration discussed in this section.

Startup Settings

Some common boot options such as enabling debugging mode are available in the start up options. In Windows 10, the settings can be accessed in Settings, Update and Security, select Recovery. Under Advanced startup, select Restart Now. When the PC reboots, select Startup options. Then select Troubleshoot > Advanced options > Startup Settings , then select Restart button. When the PC restarts, you will be able to set the available startup options.

System Configuration Utility

Use the System Configuration Utility (MSConfig.exe) instead of BCDEdit when possible. For more information, see How to open MSConfig in Windows 10.

Syntax

Parameters

[{ID}]
The {ID} is the GUID that is associated with the boot entry. If you do not specify an {ID}, the command modifies the current operating system boot entry. If a boot entry is specified, the GUID associated with the boot entry must be enclosed in braces { }. To view the GUID identifiers for all of the active boot entries, use the bcdedit /enum command. The identifier for the current boot entry is {current}. For more information about this option, use the following command: bcdedit /? ID

Note

If you are using Windows PowerShell, you must use quotes around the boot entry identifier, for example: '{49916baf-0e08-11db-9af4-000bdbd316a0}' or '{current}'.

datatypevalue

Use the command line help for BCDEdit to display information available for a specific version of Windows.

The following sections describe some common datatypes and their associated values.

Boot Settings

bootlog [ yes | no ]
Enables the system initialization log. This log is stored in the Ntbtlog.txt file in the %WINDIR% directory. It includes a list of loaded and unloaded drivers in text format.

bootmenupolicy [ Legacy | Standard ]
Defines the type of boot menu the system will use. ForWindows 10, Windows 8.1, Windows 8 and Windows RT the default is Standard. For Windows Server 2012 R2, Windows Server 2012, the default is Legacy. When Legacy is selected, the Advanced options menu (F8) is available. When Standard is selected, the boot menu appears but only under certain conditions: for example, if there is a startup failure, if you are booting up from a repair disk or installation media, if you have configured multiple boot entries, or if you manually configured the computer to use Advanced startup. When Standard is selected, the F8 key is ignored during boot. Windows 8 PCs start up quickly so there isn't enough time to press F8. For more information, see Windows Startup Settings (including safe mode).

Note

The option is available starting with Windows 8 and Windows Server 2012. You can also use the onetimeadvancedoptions to use the Advanced options (F8) menu (Legacy) one time on the next boot.

bootstatuspolicypolicy

Controls the boot status policy. The boot status policy can be one of the following:

Boot Status Policy	Description
DisplayAllFailures	Displays all errors if there is a failed boot, failed shutdown, or failed checkpoint. The computer will fail over to the Windows recovery environment on reboot.
IgnoreAllFailures	Ignore errors if there is a failed boot, failed shutdown, or failed checkpoint. The computer will attempt to boot normally after an error occurs.
IgnoreShutdownFailures	Only ignore errors if there is a failed shutdown. If there is a failed shutdown, the computer does not automatically fail over to the Windows recovery environment on reboot. This is the default setting for Windows 8.
IgnoreBootFailures	Only ignore errors if there is a failed boot. If there is a failed boot, the computer does not automatically fail over to the Windows recovery environment on reboot.
IgnoreCheckpointFailures	Only ignore errors if there is a failed checkpoint. If there is a failed checkpoint, the computer does not automatically fail over to the Windows recovery environment on reboot. The option is available starting with Windows 8 and Windows Server 2012.
DisplayShutdownFailures	Displays errors if there is a failed shutdown. If there is a failed shutdown, the computer will fail over to the Windows recovery environment on reboot. Ignores boot failures and failed checkpoints. The option is available starting with Windows 8 and Windows Server 2012.
DisplayBootFailures	Displays errors if there is a failed boot. If there is a failed boot, the computer will fail over to the Windows recovery environment on reboot. Ignores shutdown failures and failed checkpoints. The option is available starting with Windows 8 and Windows Server 2012.
DisplayCheckpointFailures	Displays errors if there is a failed checkpoint. If there is a failed checkpoint, the computer will fail over to the Windows recovery environment on reboot. Ignores boot and shutdown failures. The option is available starting with Windows 8 and Windows Server 2012.

quietboot [ on | off ]
Controls the display of a high-resolution bitmap in place of the Windows boot screen display and animation.

Note

Do not use the quietboot option in Windows 8 as it will prevent the display of bug check data in addition to all boot graphics.

sos [ on | off ]
Controls the display of the names of the drivers as they load during
