The Basic Input/Output System (
BIOS) is a crucial component of your computer’s hardware operation. It manages various components and provides a stable way for devices to start up. When you turn on your computer, the BIOS tests and activates everything needed to start running before handing over control to the operating system.
In modern computers, the terms BIOS and UEFI (Unified Extensible Firmware Interface) are often used interchangeably. While they serve similar purposes, they differ in how they achieve their goals.
There are three primary methods to reset your computer’s BIOS or UEFI settings:
- Reset internally from your device’s BIOS or UEFI menu
- Reset by removing or replacing the CMOS battery
- Clear and reset BIOS settings by clearing your motherboard jumper
When Should You Reset Your BIOS Settings?
While BIOS issues are uncommon for most users, you may need to reset your BIOS settings to:
- Diagnose or address hardware issues
- Perform a BIOS password reset when having trouble booting up
- Revert your system after making other changes
Resetting your BIOS is a simple but powerful fix for CMOS or hardware compatibility issues. Resetting the BIOS will restore the default settings, which can solve various hardware configuration problems.
How to Reset BIOS Settings on Windows PCs
1. Reset Internally from BIOS or UEFI Menu
This is the safest and most straightforward method:
For Windows 10 and later:
- Hold down the Shift key while restarting your computer
- Select Troubleshoot > Advanced Options > UEFI Firmware Settings > Restart
In the BIOS/UEFI setup menu:
- Look for options like “Load Setup Defaults” or “Load Default Options”
- To access the BIOS setup utility, restart your computer and press the key indicated during startup (usually F2, F10, DEL, or ESC)
- Confirm the reset and exit
2. Reset by Removing and Replacing the CMOS Battery
Not all motherboards have a CMOS battery, but if yours does, this method is typically applicable to
desktop computers:
- Turn off your PC and disconnect all power sources
- Ground yourself to prevent static damage
- Locate and carefully remove the CMOS battery
- Wait several minutes, then reinsert the battery (or replace with a new one)
- Reassemble your computer and boot up
3. Clear and Reset BIOS Settings via Motherboard Jumper
This method is typically limited to desktop PCs and involves using the CMOS jumper:
- Consult your motherboard manual to locate the CMOS reset jumper
- Power down and unplug your computer
- Move the jumper to the “clear” position (usually covering two specific pins)
- Wait 5-10 seconds, then move the jumper back to its original position
- Reassemble your computer and boot up
Additional Tips and Precautions
- Always back up important data before making BIOS changes.
- If unsure, consult your device’s manual or contact manufacturer support
- Be cautious when making changes in BIOS, as incorrect settings can cause system instability
- Resetting the BIOS does not impact the files stored by the operating systems, as the file systems utilized by operating systems differ significantly from those used by BIOS and firmware

Conclusion
Resetting your BIOS can be a powerful troubleshooting tool when facing hardware issues or after making unwanted changes. While it may seem technical, following these steps carefully can help resolve many computer problems. Remember, when in doubt, it’s always best to consult with a professional or your device’s manufacturer for guidance.
