Accessing the BIOS (Basic Input/Output System) on your Lenovo laptop is crucial for various tasks, including changing the boot order, enabling virtualization, troubleshooting hardware issues, and configuring system settings. This comprehensive guide provides multiple methods to enter the BIOS on Lenovo laptops, catering to different models and user preferences. Understanding these methods empowers you to optimize your Lenovo laptop’s performance and resolve potential issues.
Understanding the BIOS and Its Importance
The BIOS is firmware embedded on a small chip on your laptop’s motherboard. It’s the first software that runs when you power on your computer, performing essential tasks such as initializing hardware components and loading the operating system. Accessing the BIOS allows you to modify system settings that are not accessible within the operating system itself. It’s like the control panel for your laptop’s fundamental operations.
Why would you need to access the BIOS? Imagine you’re trying to install a new operating system from a USB drive. You’ll likely need to change the boot order in the BIOS to prioritize booting from the USB drive instead of the hard drive. Or perhaps you want to enable virtualization to run virtual machines more efficiently. The BIOS offers the settings to accomplish these tasks and many more.
Common Methods to Enter BIOS on a Lenovo Laptop
Lenovo laptops, like many other brands, offer several ways to access the BIOS. These methods typically involve pressing specific keys during the boot process or utilizing advanced startup options within Windows. Let’s explore these methods in detail.
Using the Function Keys (F1, F2, F12)
The most common method to enter the BIOS on a Lenovo laptop involves pressing a function key during startup. The specific key varies depending on the model, but F1, F2, and F12 are the most frequently used.
To use this method, completely shut down your Lenovo laptop. Power it back on and immediately begin repeatedly pressing the designated function key. Continue pressing the key until the BIOS setup utility appears. The Lenovo splash screen may briefly display which key to press. If you miss it, try the F1, F2 and F12 keys one by one.
Keep in mind that some Lenovo models may require you to press and hold the Fn key along with the function key. This is especially common on newer models. Experiment to see which combination works for your specific laptop. Timing is crucial; press the key early in the boot process.
The Novo Button Method
Many Lenovo laptops feature a small, recessed button called the “Novo button.” This button provides access to a boot menu that allows you to enter the BIOS, select a boot device, or perform system recovery. The location of the Novo button varies depending on the model, but it’s typically found near the power button or on the side of the laptop. The Novo button is a lifesaver when function keys fail.
To use the Novo button, completely shut down your Lenovo laptop. Locate the Novo button and use a straightened paperclip or a similar object to gently press and hold the button. The laptop should power on and display the Novo Button Menu.
From the Novo Button Menu, use the arrow keys to select “BIOS Setup” and press Enter. This will take you directly to the BIOS setup utility. The Novo button method is particularly useful if you are having trouble with the function keys or if you need to access the BIOS from a cold boot.
Accessing BIOS from Windows Advanced Startup Options
If your Lenovo laptop is already running Windows, you can access the BIOS through the Advanced Startup Options menu. This method is especially helpful if you’re unable to use the function keys or the Novo button.
To access the Advanced Startup Options, click on the Windows Start button, then click on the Power button. Hold down the Shift key while clicking on “Restart.” This will restart your laptop into the Advanced Startup Options menu.
From the Advanced Startup Options menu, select “Troubleshoot,” then “Advanced options,” and finally “UEFI Firmware Settings.” If you don’t see “UEFI Firmware Settings”, it means your computer might not support this feature or it’s disabled. The label may be different depending on the Windows version. Click “Restart” to boot into the BIOS.
This method leverages the operating system to initiate the BIOS access, providing a convenient alternative to the traditional key-pressing approach.
Troubleshooting BIOS Access Issues
Sometimes, entering the BIOS can be challenging. Several factors can prevent you from accessing the BIOS, including fast startup settings, keyboard issues, or incorrect key presses. Here are some troubleshooting tips to help you overcome these obstacles.
Disabling Fast Startup in Windows
Windows’ Fast Startup feature can sometimes interfere with the BIOS access process. Fast Startup is a hybrid shutdown mode that saves a snapshot of your system to a file, allowing for quicker boot times. However, this can prevent the system from recognizing key presses during startup.
To disable Fast Startup, go to Control Panel > Power Options > Choose what the power buttons do. Click on “Change settings that are currently unavailable.” Uncheck the box next to “Turn on fast startup (recommended)” and click “Save changes.” Disabling Fast Startup ensures the system fully reboots, allowing BIOS access.
After disabling Fast Startup, try the function key or Novo button methods again to access the BIOS. This should resolve any conflicts caused by the Fast Startup feature.

A malfunctioning keyboard can also prevent you from entering the BIOS. Ensure your keyboard is properly connected and functioning correctly. Try using a different keyboard to rule out any hardware issues.
If you’re using a wireless keyboard, make sure it’s paired with your laptop and has sufficient battery power. Sometimes, wireless keyboards aren’t fully initialized during the early boot process, preventing them from registering key presses. A wired keyboard is often more reliable for accessing the BIOS.
Verifying Key Presses and Timing
Incorrect key presses or improper timing can also prevent BIOS access. Double-check the correct function key for your Lenovo laptop model and ensure you’re pressing it repeatedly and early enough in the boot process.
Some Lenovo models may require you to press and hold the Fn key along with the function key. Experiment with different key combinations to find the correct one. Precision and persistence are key to successfully accessing the BIOS.
Checking for Legacy BIOS Settings
On older Lenovo models, you might need to enable legacy BIOS settings in the operating system or through other system utilities. These settings might be disabled by default, preventing access to the BIOS through traditional methods. Consult your laptop’s manual or Lenovo’s support website for instructions on enabling legacy BIOS settings.
Navigating the BIOS Interface
Once you’ve successfully entered the BIOS, you’ll be presented with a text-based or graphical interface that allows you to configure various system settings. The BIOS interface typically includes several sections, such as “Main,” “Boot,” “Security,” and “Exit.” Understanding the BIOS interface is vital for making necessary changes.
Use the arrow keys to navigate through the different sections and settings. Press Enter to select a setting and modify its value. Use the Esc key to go back to the previous menu. Be cautious when making changes to BIOS settings, as incorrect configurations can lead to system instability or prevent your laptop from booting correctly.

What are the most common keys to enter BIOS on a Lenovo laptop?
The most common keys to enter the BIOS setup on a Lenovo laptop are F2, F12, Delete, and sometimes Fn + F2. The specific key can vary depending on the model and age of the laptop. Always refer to your laptop’s documentation or look for a brief on-screen prompt during the boot process that indicates the correct key to press. This prompt usually appears just after powering on the laptop and before the operating system starts loading.
If you miss the prompt, try repeatedly pressing the identified key (or a combination of keys if suggested) immediately after powering on the laptop. For newer models with faster boot times, it can be challenging to time the key press correctly. In such cases, using the Novo button method (explained in more detail in other FAQs) might be a more reliable way to access the BIOS setup.
Where is the Novo button located and what does it do?
The Novo button is a small, recessed button typically located on the side or near the power button of Lenovo laptops. Its specific location varies depending on the model but is often found near the headphone jack, the power adapter port, or on the left side of the laptop. The Novo button is usually marked with a small curved arrow icon. Some models might require you to use a paperclip or similar small object to press the button.
Pressing the Novo button (with the laptop powered off) allows you to access the Novo Button Menu. This menu provides options to recover the system, change boot order, or access the BIOS setup. This is a convenient alternative to pressing specific keys during the boot process, especially useful for laptops with fast boot times where timing the key press can be difficult.
How do I enter BIOS if my Lenovo laptop boots too quickly?
Modern Lenovo laptops often have very fast boot times, making it difficult to press the correct key to enter BIOS. The most reliable method is to use the Novo button, as described in another FAQ. This button allows you to access a boot menu that includes the option to enter BIOS setup without having to time a key press during the initial boot process. Ensure the laptop is completely powered off before pressing the Novo button.
Another approach is to disable the fast startup feature in Windows. To do this, go to Control Panel -> Power Options -> Choose what the power buttons do -> Change settings that are currently unavailable. Then, uncheck the “Turn on fast startup (recommended)” box. After disabling fast startup, your laptop will boot slower, giving you more time to press the correct key (usually F2, F12, or Delete) to enter BIOS.
What should I do if none of the common BIOS keys work?
First, double-check your Lenovo laptop’s documentation or the manufacturer’s website for the specific BIOS key combination for your model. Sometimes, the key combination can be unique. Ensure you are pressing the correct key or key combination immediately after powering on the laptop, before the operating system starts loading. Try pressing the key repeatedly rather than just once.
If you’ve tried all common keys and the documented key without success, the next step is to use the Novo button (if available on your model). This is the most reliable alternative method. If the Novo button doesn’t work or is unavailable, there might be a hardware issue preventing you from accessing the BIOS. In such a case, contacting Lenovo support or a qualified computer technician is recommended.
Can I enter BIOS from within Windows?
Yes, you can enter the UEFI (Unified Extensible Firmware Interface), which is the modern replacement for BIOS, from within Windows 10 and 11. This method is particularly useful if you are having difficulty pressing the correct key during startup.
To access the UEFI settings from Windows, go to Settings -> Update & Security -> Recovery. Under “Advanced startup,” click “Restart now.” After the laptop restarts, you’ll see a blue screen with options.

What is the difference between BIOS and UEFI?
BIOS (Basic Input/Output System) is the traditional firmware interface for PCs. It’s a legacy system that has been used for decades. BIOS is a text-based interface that provides basic hardware initialization and allows you to configure system settings. It uses the Master Boot Record (MBR) partitioning scheme, which has limitations on the size of bootable partitions and the number of partitions.
UEFI (Unified Extensible Firmware Interface) is the modern replacement for BIOS. It offers a graphical user interface with mouse support and supports more advanced features such as Secure Boot. UEFI supports the GUID Partition Table (GPT) partitioning scheme, which overcomes the limitations of MBR, allowing for larger partitions and more flexible boot options. Most modern Lenovo laptops use UEFI instead of BIOS.
What are some common reasons for needing to access the BIOS?
One common reason to access the BIOS/UEFI is to change the boot order. This is necessary if you want to boot from a USB drive or DVD to install a new operating system, run a diagnostic tool, or recover your system. By changing the boot order, you can tell the laptop to check these devices before the internal hard drive.
Another frequent reason is to adjust hardware settings, such as enabling or disabling certain devices, configuring memory settings, or adjusting fan speeds. In some cases, you might also need to enable virtualization features in the BIOS/UEFI for running virtual machines. Additionally, users may want to check the system information, such as the BIOS version, CPU model, and amount of installed RAM, which is readily available in the BIOS/UEFI interface.
