How to Check Your Device's Boot Mode: UEFI or Legacy?

Understanding your device's boot mode is crucial for troubleshooting and optimizing system settings. Devices generally operate in one of two boot modes: UEFI (Unified Extensible Firmware Interface) or Legacy (BIOS). In this guide, we will walk you through a simple method to check your device's boot mode using PowerShell.

What is Boot Mode?

Boot mode refers to the method in which a computer starts up and loads the operating system. The two main types of boot modes are:

UEFI (Unified Extensible Firmware Interface): A modern firmware interface that supports larger drives, faster boot times, and improved security features.

Legacy (BIOS): The traditional firmware interface used in older systems which has limitations in terms of drive size and boot speed.

Identifying which boot mode your device is using can help you to configure it properly for your needs.

Checking Boot Mode with PowerShell

Using PowerShell to check the boot mode is a straightforward task. Please follow the steps outlined below:

Step 1: Run PowerShell as an Administrator

Before executing any command, ensure you are running PowerShell in elevated mode (as an administrator). Here’s how to do it:

Click on the Start menu.

Type “PowerShell”.

Right-click on Windows PowerShell and select Run as administrator.

Step 2: Enter the Command

Now, you're ready to input the command to check the boot mode:

Explanation of the Command:

bcdedit: This command queries the Boot Configuration Data (BCD) store.

Select-String "path.*efi": This part searches for the presence of .efi files in the boot path.

The if statement checks if the $BootMode variable is null (which indicates that no .efi files were found). If true, the device is in Legacy mode. If .efi is found, it indicates UEFI mode.

Step 3: Interpret the Results

Upon executing the above command, you will receive an output indicating the boot mode of your computer:

If you see UEFI: Your system is running in UEFI mode.

If you see Legacy: Your system is running in Legacy mode.

Conclusion

By following these simple steps in PowerShell, you can easily determine whether your device is operating in UEFI or Legacy boot mode. This information is especially useful for configuration tasks such as installing new operating systems, upgrading hardware, or troubleshooting boot-related issues.

Now that you know how to check your device's boot mode, you'll be better equipped to manage system settings effectively. If you have any questions or need further assistance, feel free to leave a comment below!
