UEFI (Unified Extensible Firmware Interface) is the modern replacement for the traditional BIOS found on older computers. It initializes your computer’s hardware, verifies connected devices, and starts the Windows operating system. UEFI also provides advanced features such as Secure Boot, TPM support, faster startup times, larger drive compatibility, and an improved graphical configuration interface. While most users rarely need to modify UEFI settings, incorrect changes can lead to boot failures, hardware detection problems, Windows installation errors, or reduced system stability.
If you’ve changed UEFI settings and your computer is no longer functioning correctly, resetting the firmware to its factory defaults is often the safest solution. Restoring the default configuration removes custom settings, including overclocking profiles, boot order changes, virtualization options, and Secure Boot modifications, allowing your system to return to the manufacturer’s recommended configuration. This process does not affect your Windows installation or personal files, making it a useful first step when troubleshooting firmware-related issues.
This guide explains several methods to reset UEFI firmware settings in Windows 11 and Windows 10, what happens after the reset, and the settings you may need to reconfigure afterward.
What Are UEFI Firmware Settings?
UEFI firmware settings control how your computer’s hardware operates before Windows loads.
These settings determine how the motherboard initializes components such as the processor, memory, storage devices, graphics hardware, and boot devices.
Modern UEFI firmware also manages features including Secure Boot, TPM, virtualization, fan controls, and storage controller modes.
When Should You Reset UEFI Firmware Settings?
Resetting UEFI settings is recommended if:
- Your computer won’t boot after changing firmware settings.
- Windows crashes after modifying UEFI options.
- Hardware is no longer detected correctly.
- You’re troubleshooting startup or installation problems.
- You want to remove incorrect firmware configurations.
- An overclock has made the system unstable.
Restoring the default configuration often resolves problems caused by accidental or unsupported firmware changes.
Things to Know Before Resetting UEFI
Resetting UEFI settings restores the manufacturer’s default configuration.
It does not:
- Delete Windows
- Remove installed applications
- Erase personal files
- Format your storage drive
However, it may reset settings such as:
- Boot order
- Secure Boot
- TPM configuration
- CPU overclocking
- XMP or EXPO memory profiles
- Virtualization
- Fan settings
- SATA or NVMe configuration
- Date and time
If you’ve customized these settings, make a note of them before performing the reset.

- Restore Defaults
- Load Default Configuration
- Factory Defaults
Select the option.
Confirm the reset.
Save your changes.
Exit the firmware setup.
The computer restarts using the factory default settings.
Method 2: Enter UEFI from Windows
Windows allows you to access the UEFI firmware without pressing startup keys.
Open Settings.
Go to System > Recovery.
Under Advanced startup, click Restart now.
After your computer restarts, select:
Troubleshoot > Advanced options > UEFI Firmware Settings
Click Restart.
Your computer boots directly into the UEFI setup utility.
From there, restore the default settings using the firmware menu and save the changes before exiting.
This method is especially useful if your computer boots into Windows too quickly to press the firmware access key.
Method 3: Reset UEFI by Clearing CMOS
If you can’t access the firmware interface, clearing the CMOS memory restores the default UEFI settings.
Shut down the computer.
Disconnect the power cable.
If using a laptop, disconnect the charger and remove the battery if possible.
Open the computer case.
Locate the CMOS coin-cell battery on the motherboard.
Carefully remove it.
Wait five to ten minutes.
Reinstall the battery.
Reconnect power.
Turn on the computer.
The firmware loads its default configuration during startup.
Some laptops use integrated batteries, making this method more difficult.
Method 4: Use the Clear CMOS Jumper
Many desktop motherboards include a dedicated Clear CMOS jumper.
Power off the computer.
Disconnect all power sources.
Locate the Clear CMOS jumper using your motherboard manual.
Move the jumper to the reset position.
Wait the recommended amount of time.
Return the jumper to its original position.
Reconnect power.
Restart the computer.
The UEFI firmware should load the factory default settings.
Always follow the instructions provided by your motherboard manufacturer.
Method 5: Use a Dedicated Clear CMOS Button
Some modern gaming and enthusiast motherboards include a Clear CMOS button.
Power off the computer.
Press the Clear CMOS button according to the manufacturer’s instructions.
Turn the computer back on.
The motherboard automatically restores the default firmware settings.
This method is quick and doesn’t require opening the computer.
What Happens After Resetting UEFI?
After the reset, your motherboard loads the manufacturer’s recommended settings.
Windows should boot normally if the default configuration matches your hardware.
However, some settings may require attention.
You may need to:
- Set the correct boot drive.
- Restore the system date and time.
- Re-enable XMP or EXPO memory profiles.
- Enable virtualization for virtual machines.
- Verify Secure Boot is enabled.
- Confirm TPM is enabled for Windows 11.
Most users only need to review these settings once after the reset.
Secure Boot and TPM After Reset
Windows 11 requires TPM 2.0 and Secure Boot on supported systems.
After resetting UEFI settings, verify that both features remain enabled.
If either setting is disabled, Windows may display compatibility warnings or certain security features may not function correctly.
You can check these options from the Security or Boot section of your UEFI firmware.
Common Problems After Resetting UEFI
If Windows displays No Bootable Device, verify that the Windows SSD or hard drive is selected as the first boot device.
If storage drives aren’t detected, check the storage controller configuration and ensure all cables are properly connected.
Some users notice the system clock resets after clearing CMOS.
Correct the date and time in the firmware setup or allow Windows to synchronize them automatically.
If virtualization is required for Hyper-V, Windows Sandbox, or Android emulators, re-enable it after the reset.
UEFI Reset vs BIOS Reset
On modern computers, UEFI has largely replaced the traditional BIOS.
Resetting UEFI and resetting BIOS perform essentially the same task—restoring firmware settings to their factory defaults.
The difference lies mainly in the firmware technology.
UEFI provides modern features such as Secure Boot, graphical interfaces, GPT drive support, and faster startup, while legacy BIOS offers a simpler, older firmware environment.
UEFI Reset vs UEFI Update
Resetting UEFI restores the current firmware settings without changing the firmware version.
Updating UEFI installs newer firmware released by the motherboard or computer manufacturer.
An update may improve compatibility, fix bugs, enhance security, or add support for newer hardware.
Resetting is generally safe and is often used for troubleshooting, while updating should only be performed when necessary and according to the manufacturer’s instructions.
Tips Before Changing UEFI Settings Again
Only modify settings that you understand.
Record important configuration values before making changes.
Avoid unnecessary overclocking if system stability is your priority.
Keep your motherboard firmware up to date only when updates provide meaningful improvements or resolve issues affecting your system.
If you need to experiment with firmware settings, change one option at a time so it’s easier to identify the cause of any problems.
Is Resetting UEFI Safe?
Yes. Resetting UEFI firmware settings is considered a safe troubleshooting procedure.
It restores the motherboard’s default configuration without affecting Windows, installed applications, or personal files.
In many situations, it resolves boot failures, hardware detection issues, installation errors, and system instability caused by incorrect firmware settings.
Conclusion
Resetting UEFI firmware settings is one of the simplest and safest ways to resolve problems caused by incorrect firmware configuration. Whether your computer is experiencing startup failures, hardware detection issues, instability after overclocking, or Windows installation problems, restoring the default UEFI settings often returns the system to a stable state without affecting your operating system or personal files. Modern computers provide several methods for performing this reset, including the UEFI setup utility, Windows Advanced Startup, Clear CMOS jumpers, dedicated reset buttons, and removing the CMOS battery when necessary.
After resetting the firmware, review important settings such as the boot order, Secure Boot, TPM, virtualization, and memory profiles to ensure your system operates correctly, especially if you’re running Windows 11.
