How can you enable or disable secure boot and fast boot in BIOS settings? (2024)

BIOS stands for Basic Input/Output System, and it is a small program that runs on a chip on your motherboard. It controls the communication between your hardware and your operating system, and it also initializes and tests your hardware components when you turn on your computer. To access the BIOS settings, you need to press a certain key or combination of keys during the boot process, before the operating system loads. The exact key or keys depend on your computer model and manufacturer, but some common ones are F2, F10, F12, Esc, or Del.

Secure boot is a BIOS setting that verifies the digital signature of the software that tries to load during the boot process, such as the operating system, the bootloader, or the drivers. If the software is not signed by a trusted authority, or if the signature is corrupted or modified, secure boot will block it from loading and display an error message. This way, secure boot can prevent malware, rootkits, or unauthorized operating systems from compromising your computer.

To enable or disable secure boot, you need to access the BIOS settings and look for the secure boot option. The location and name of this option may vary depending on your BIOS version and manufacturer, but it is usually found under the security, boot, or advanced tab. If you find the secure boot option, you can toggle it on or off by using the arrow keys and the enter key. Some BIOS may require you to enter a password or a code to change the secure boot setting. If you do not find the secure boot option, it may mean that your BIOS does not support it, or that it is hidden or locked by default. In that case, you may need to update your BIOS, or check your manufacturer's website for more instructions.

Fast boot is a BIOS setting that reduces the boot time by skipping some of the hardware initialization and testing steps that normally occur during the boot process. For example, fast boot may skip the memory test, the device detection, or the logo display. This way, fast boot can save you some seconds or minutes every time you start your computer.

To enable or disable fast boot, you need to access the BIOS settings and look for the fast boot option. The location and name of this option may vary depending on your BIOS version and manufacturer, but it is usually found under the boot or advanced tab. If you find the fast boot option, you can toggle it on or off by using the arrow keys and the enter key. Some BIOS may have different levels of fast boot, such as normal, fast, or ultra fast. If you do not find the fast boot option, it may mean that your BIOS does not support it, or that it is hidden or locked by default. In that case, you may need to update your BIOS, or check your manufacturer's website for more instructions.

Secure boot and fast boot are both useful BIOS settings that can enhance your computer's security and performance. However, they also have some drawbacks and limitations that you should be aware of before enabling or disabling them. Secure boot can prevent malware and rootkits from loading during the boot process, as well as protect your data and system integrity from tampering or corruption. On the other hand, it can limit your choice of operating systems, bootloaders, or drivers that are not signed by a trusted authority. Fast boot can reduce the boot time by skipping some of the hardware initialization and testing steps, while also saving energy and wear and tear on your hardware components. But it can also prevent you from accessing the BIOS settings or other boot options by shortening the window of time to press the required key or keys. Additionally, both secure boot and fast boot can cause compatibility issues with some hardware or software, as well as make it harder to troubleshoot or recover your system in case of a problem.
