This file system has been known as BIOS for a long time. Because it doesn’t display unless an operating system is installed, most users won’t interact with it much. Because few people deal with this file system, they may be unaware that BIOS has been replaced with UEFI BIOS on many devices.

If you’re a desktop/laptop/computer component maker, the UEFI BIOS has superseded the old BIOS, which we now refer to as Legacy BIOS. If you’re a desktop/laptop/computer component manufacturer, there’s quite a difference between the two. The distinction for end users is that UEFI BIOS is more secure.
Switch UEFI BIOS to Legacy BIOS
UEFI BIOS, on the other hand, is the new file system found on current PCs and laptops. UEF BIOS is preferred by modern operating systems, but there are exceptions. If you’re trying to install a Linux distribution that won’t install on UEFI BIOS, these exceptions may force you to switch UEFI BIOS to Legacy BIOS.

You can switch UEFI BIOS to Legacy BIOS in this instance. This does not necessitate the use of any complex tools. Everything you need is already installed on your PC; all you have to do now is figure out which settings need to be tweaked.
- Shut down your system.
- Turn the system On and tap the F2 key to boot to BIOS.
- Go to the Boot tab (may differ based on your BIOS layout).
- Look for an option called Secure Boot.
- Select it, and tap Enter.
- Change its value to Disabled.
- Tap the F10 key to save the changes and Exit BIOS.
- Turn your system off, and then On.
- Tap the F2 key to boot to BIOS.
- You will boot to Legacy BIOS.
Go back to UEFI BIOS
All you have to do to return to UEFI BIOS is enable Secure Boot from Legacy BIOS.
- Power your system On.
- Tap the F2 key to access BIOS.
- Go to the Boot tab.
- Look for Secure Boot and select it.
- Tap Enter.
- Select Enable.
- Tap F10 to save and exit.
- When you next boot to BIOS, you will see UEFI BIOS.
BIOS settings are never the same for different systems and device manufacturers. It’s possible that your BIOS doesn’t have a Boot tab. It could be called something else, or the Secure Boot option could be hidden behind a different tab.
You might not see a Secure Boot option in some cases. In its place, you may see a Legacy boot option or something similar.
