Entering the BIOS (Basic Input/Output System) without restarting Windows 11 isn't possible in the traditional sense, as the BIOS is a pre-boot environment. To access the BIOS, you need to restart your computer. However, you can streamline the process by using the advanced startup options available in Windows 11. which allow you to reboot directly into the BIOS or UEFI (Unified Extensible Firmware Interface) settings.
Accessing BIOS from Windows 11 Using Advanced Startup
Open Settings:
Click on the Start menu and select Settings (or press Win + I).
Navigate to Recovery Options:
In the Settings window, click on System in the left-hand menu.
Scroll down and select Recovery.
Advanced Startup:
Under the Recovery options section, you will see Advanced startup. Click on the Restart now button next to it. A confirmation dialog will appear, click on Restart now again.
Choose an Option:
After your computer restarts, you will see a blue screen with several options. Select Troubleshoot.
Advanced Options:
In the Troubleshoot menu, select Advanced options.
UEFI Firmware Settings:
Finally, select UEFI Firmware Settings and click Restart. Your computer will restart and enter the BIOS/UEFI settings automatically.
Accessing BIOS Using the Shift + Restart Method
Open Start Menu:
Click on the Start menu.
Power Menu:
Click on the Power button to open the power options (Sleep, Shut down, Restart).
Shift + Restart:
Hold down the Shift key on your keyboard and click on Restart.
Troubleshoot and Advanced Options:
Similar to the previous method, after your computer restarts, you will see a blue screen with options. Select Troubleshoot, then Advanced options, and finally UEFI Firmware Settings.
Accessing BIOS from Command Prompt
Open Command Prompt:
Click on the Start menu, type cmd, and select Command Prompt from the search results.
Execute Shutdown Command:
In the Command Prompt window, type the following command and press Enter:
sh
复制代码
shutdown /r /o /f /t 00
This command will restart your computer and take you to the advanced startup options menu.
Follow the Advanced Options:
After your computer restarts, you will again see the blue screen with several options. Select Troubleshoot, then Advanced options, and finally UEFI Firmware Settings.
Understanding BIOS and UEFI
BIOS:
BIOS is firmware used during the booting process (power-on startup) on IBM PC compatible computers.
It initializes and tests the system hardware components and loads a bootloader or an operating system from a mass memory device.
UEFI:
UEFI (Unified Extensible Firmware Interface) is a modern version of BIOS. It offers more features, a graphical interface, and support for larger hard drives and secure boot.
Key Differences:
User Interface:
BIOS typically has a text-based interface.
UEFI often features a more user-friendly graphical interface.
Booting:
UEFI supports faster boot times.
UEFI can boot from drives larger than 2TB, unlike BIOS.
Security:
UEFI supports secure boot, which helps prevent unauthorized boot loaders from loading.
Troubleshooting Common BIOS/UEFI Access Issues
Fast Startup:
Windows 11 includes a feature called Fast Startup which might bypass the option to access the BIOS during boot. You can disable Fast Startup:
Open Control Panel.
Go to Power Options > Choose what the power buttons do.
Click on Change settings that are currently unavailable.
Uncheck Turn on fast startup and save changes.
Multiple Key Presses:
Some systems require multiple key presses to enter BIOS during the boot process (e.g., pressing F2 repeatedly).
Secure Boot:
If Secure Boot is enabled, it may prevent access to certain BIOS settings. You may need to disable it temporarily from within BIOS to make changes.
Firmware Updates:
Make sure your motherboard’s firmware is up to date. Sometimes, outdated firmware can cause issues accessing BIOS.
While you can't enter the BIOS without restarting your computer, Windows 11 provides streamlined methods to restart directly into the BIOS or UEFI settings through advanced startup options. These methods make it easier to access the BIOS/UEFI without having to press specific keys during the boot process, which can be missed if the boot process is too fast. By following the steps outlined above, you can efficiently access and configure your BIOS or UEFI settings as needed.
