All computers come with a basic file system loaded on memory. This file system can take control of some hardware components at a basic level, and allows you to make system changes such as setting a password before seeing the OS boot screen. is inserted.
For a long time, this file system was called BIOS. Most users will not interact with it significantly as it does not show if an operating system is installed. Because many users do not interact with this file system, they may not be aware that BIOS has replaced BIOS on many systems.
UEFI BIOS has replaced the old BIOS we now call Legacy BIOS. There is a slight difference between the two if you are a desktop / laptop / computer manufacturer. For end users, the difference is that UEFI BIOS is more secure.
Change UEFI BIOS to Legacy BIOS
Although UEFI BIOS is the new file system used on today’s desktops and laptops. Modern operating systems prefer UEF BIOS but there will be exceptions. These exceptions may require you to have Legacy BIOS instead of UEFI BIOS eg, if you are trying to install a Linux distro do not install UEFI BIOS.
In this case, you can change UEFI BIOS to Legacy BIOS. Complex machines are not involved in doing this. Everything you need is already on your system and you only need to know what setting needs to be changed.
- shut down your system.
- Turn the Forward system and tap on the F2 key to boot to BIOS. If the F2 key is not working, check out how to get BIOS for your PC here.
- Go to Tab boot (this may vary based on your BIOS design).
- Look for a so-called option Secure boot.
- Choose it, and tap Enter.
- Change its value to Disabled.
- Tap on the July F10 to save the changes and issue a BIOS.
- Turn on your system off, and then Next.
- Tap on the F2 key to boot to BIOS.
- You will start to Legacy BIOS.
Revert to UEFI BIOS
If you need to revert to UEFI BIOS, all you have to do is enable Boot Secure from Legacy BIOS.
- Power to Forward system.
- Tap on the July F2 to access BIOS.
- Go to Tab boot.
- look for Secure boot and select it.
- Tap on it Enter.
- Choose Make it possible.
- Tap on F10 to save and exit.
- When you reboot into BIOS, you’ll see BIOS UEFI.
BIOS settings are never the same for different systems and device manufacturers. You may not see the Boot tab in your BIOS. It may be called something else, or the Secure Boot option under the tab may be completely different.
In some cases, you may not see the Secure Boot option. Instead, you may see a Legacy shoe option, or something similar instead.
To avoid error, you can Google what the legacy / UEFI BIOS setting is called for your particular device.
