Why enable UEFI mode?
UEFI mode is the newer more powerful version of BIOS. Most modern systems are able to boot in UEFI mode.
UEFI is required to use features like Secure Boot, which is becoming increasingly required by software and Windows.
Specifics
This guide was created with newer ASUS TUF motherboards. Steps might vary slightly based on your system specs, so make sure to Google <Your motherboard> enable UEFI
if this guide does not help you get everything going.
Your system drive must also be set to GPT instead of MBR. If you’re not sure what your system drive is, or need to convert it: See Convert MBR drives to GPT.
Enabling UEFI mode on ASUS TUF Motherboards
Assuming you’re using a GPT drive, let’s get going!
Reboot into firmware settings
If you’re logged into Windows:
- Open this guide on another device, as your system will only show firmware settings when you’re in the UEFI/BIOS settings screen.
- Press
Start
orWindows
and search forCMD
. OpenCommand Prompt
as Administrator. - Type:
shutdown /r /fw
and press Enter to reboot your system directly into your firmware settings.
Alternatively:
- Reboot your system as normal.
- While booting: when you see your motherboard’s logo there is usually text below saying
Press F2
,F12
,Delete
or any other combination of buttons to enter Settings, BIOS or UEFI. Press that key while still on this screen. - You should now be in your BIOS/UEFI settings ready to adjust your configuration.
On my system I needed to press F2.
You should now be on your BIOS/UEFI Configuration Screen

Enable UEFI mode
This is displayed slightly differently - even from motherboard to motherboard from the same manufacturer.
- Use
F7
to enter Advanced Mode (you’ll see it at the bottom-right). You may also be able to click this, or it could be a different key. - Use the arrow keys to navigate to the
Boot
tab at the top of your screen - Click on
CSM (Compatibility Support Module)
- Click
Launch CSM
and set it toDisabled
. This will turn off Legacy mode, and enable UEFI mode. - Hit Escape, and use the Right arrow to get to the
Exit
tab. ChooseSave Changes & Reset
(Reset refers to the power, not your configuration!).
You should now boot into Windows with UEFI mode enabled!
