Are you struggling to access the BIOS settings on your computer because the UEFI option is missing? Don’t worry, you’re not alone. Many users face this issue, and it can be frustrating, especially when you need to make changes to your computer’s settings. In this article, we’ll guide you through the process of accessing BIOS when UEFI is missing, and provide you with valuable information on how to troubleshoot common issues.
Understanding BIOS and UEFI
Before we dive into the solution, let’s take a brief look at what BIOS and UEFI are, and how they differ.
What is BIOS?
BIOS (Basic Input/Output System) is a type of firmware that controls the basic functions of your computer’s hardware. It’s responsible for initializing the hardware components, such as the CPU, RAM, and storage devices, and provides a interface for the operating system to interact with the hardware. BIOS is typically stored in a ROM (Read-Only Memory) chip on the motherboard.
What is UEFI?
UEFI (Unified Extensible Firmware Interface) is a more modern type of firmware that replaces the traditional BIOS. It provides a more secure and flexible way of interacting with the hardware, and offers features such as secure boot, network boot, and faster boot times. UEFI is typically stored in a flash memory chip on the motherboard.
Why is UEFI Missing?
There are several reasons why the UEFI option might be missing from your computer’s boot menu. Here are a few possible explanations:
Legacy BIOS Mode
If your computer is set to legacy BIOS mode, the UEFI option might not be available. Legacy BIOS mode is a compatibility mode that allows older operating systems to boot on newer hardware.
Secure Boot
If secure boot is enabled on your computer, the UEFI option might be hidden. Secure boot is a feature that ensures the operating system boots securely, and prevents malware from loading during the boot process.
Boot Order
The boot order might be set to prioritize other devices, such as the hard drive or SSD, over the UEFI firmware. This can cause the UEFI option to be missing from the boot menu.

What is BIOS and how does it differ from UEFI?
BIOS (Basic Input/Output System) is a firmware that controls and configures the hardware components of a computer. It is responsible for initializing the hardware, detecting and configuring peripherals, and loading the operating system. UEFI (Unified Extensible Firmware Interface), on the other hand, is a more modern and advanced firmware that replaces the traditional BIOS. UEFI provides a more secure and flexible way of configuring the computer’s hardware and firmware.
The main difference between BIOS and UEFI is the way they interact with the operating system and the hardware. BIOS uses a 16-bit processor mode and is limited to a maximum of 1 MB of address space, whereas UEFI uses a 32-bit or 64-bit processor mode and can address much larger amounts of memory. UEFI also provides a more user-friendly interface and supports features like secure boot, network boot, and faster boot times.
Why would I need to access BIOS when UEFI is missing?
There are several reasons why you may need to access BIOS even if UEFI is missing. One reason is to configure the hardware settings, such as the boot order, fan settings, or CPU settings. Another reason is to troubleshoot hardware issues, such as a faulty RAM or a malfunctioning hard drive. You may also need to access BIOS to update the firmware or to reset the BIOS settings to their default values.
Additionally, some older systems may not have UEFI, and accessing BIOS may be the only way to configure the hardware settings. In some cases, you may need to access BIOS to enable or disable certain features, such as the USB ports or the network interface. Overall, accessing BIOS can be an essential step in troubleshooting and configuring your computer’s hardware.
How do I access BIOS when UEFI is missing?
To access BIOS when UEFI is missing, you will typically need to press a specific key or combination of keys during the boot process. The most common keys used to access BIOS are F2, F12, Del, and Esc. You may need to press these keys repeatedly or hold them down for a few seconds to enter the BIOS setup utility.
It’s essential to note that the key or combination of keys used to access BIOS may vary depending on the computer manufacturer and model. You can usually find the correct key or combination of keys in the computer’s user manual or online documentation.
