How To Change Bios Mode From Legacy To Uefi On MSI Laptop

When you buy a new computer, there are some settings that need to be configured in order for the system to work properly.

One of these settings is the BIOS mode. If this setting is not configured correctly, you may experience problems starting up your MSI computer or accessing your files.

In this blog post, we will show you how to change the BIOS mode on an MSI laptop from Legacy to UEFI.

How To Change From Legacy To UEFI MSI

This is a relatively easy process, but it’s important that you follow the instructions closely in order to avoid any potential problems.


If you’re having trouble with your MSI laptop’s touchpad, MSI Touchpad Not Working has the solution.

Make sure your touchpad is working properly so you can navigate with it in your BIOS or you can simply disable the touchpad and stick to your keyboard for navigation. Also, you can change the keyboard color on your MSI laptop to any color if your choice to see better if you are in a dark environment.

In Windows 7, 8, and 10, you can change the boot order from the Boot Options menu in your computer’s BIOS / UEFI settings. To do this, follow these steps:

  1. Restart your computer and press the "Del" key or other key that allows you to enter the BIOS / UEFI settings.
  1. In the BIOS / UEFI menu, go to the "Boot" tab and look for a "Boot Order" or "Boot Options" setting.
  1. If your BIOS / UEFI has a "Boot Order" setting, change the order of the devices so that your computer’s primary drive is listed first.


To enter BIOS on an MSI laptop, use the MSI BIOS Key Guide as a reference. Click here for a comprehensive guide on how to enter BIOS on MSI laptops.

For example, if your primary drive is a hard drive, you would move it to the top of the list.

  1. If your BIOS / UEFI has a "Boot Options" setting, enable the "Boot from USB" or "Boot from CD / DVD" option so that your computer will boot from a bootable USB drive or CD / DVD.
  1. Save your changes and exit the BIOS / UEFI menu. Your computer should now boot from its primary drive.

If you’re having trouble changing the boot order of your devices, you may need to update your BIOS / UEFI firmware.

What Is Legacy Boot Mode On MSI?

As the name suggests, legacy boot mode refers to the ability of a computer to boot up using the traditional BIOS system.

This is in contrast to the newer UEFI standard, which is gradually replacing BIOS as the primary method for booting up computers.

Many MSI laptops support both legacy and UEFI boot modes, giving users the flexibility to choose which one they want to use.


One advantage of legacy boot mode is that it is compatible with a wide range of operating systems and software.

This means that you can usually install any OS on a computer that supports legacy boot, without having to worry about compatibility issues.

Additionally, many older devices and peripherals are only compatible with legacy boot, so using this mode may be necessary if you want to use them with your computer.


However, there are also some disadvantages to using legacy boot mode. One is that it can be less secure than UEFI, since the BIOS system is relatively easy to hack.

Additionally, legacy boot mode can be slower than UEFI, since the BIOS system is not as efficient. As such, if you are looking for the best performance and security, you should use UEFI boot mode on your MSI laptop.

In short, legacy boot mode on MSI laptops is a holdover from the days when BIOS was the primary method of booting up computers.

While it has its advantages, it is generally not as good as UEFI in terms of performance and security. As such, you should usually use UEFI mode unless you have a specific reason to use legacy boot mode.

What Is UEFI Boot Mode On MSI?

The Unified Extensible Firmware Interface (UEFI) is a specification that defines a software interface between an operating system and platform firmware. UEFI is meant to replace the basic input/output system (BIOS) firmware interface used on most personal computers.

MSI laptops are UEFI enabled and thus allow you to boot from a USB or DVD drive in UEFI mode. To do so, simply change the boot order in your BIOS/UEFI settings and set the desired device as the first priority.

Once you’ve done that, you can insert your Windows installation disc or USB drive and boot from it. The MSI logo should appear on your screen and you should see the message "Press any key to boot from CD or DVD." Press a key to continue.

If you’re installing Windows from scratch, you’ll be asked to select your preferred language, time and currency format, and keyboard or input method. On the next screen, choose "Custom install."

On the "Where do you want to install Windows?" screen, select the drive you want to install Windows on and click "Next." If you don’t see this screen, or if you’re not given the option to choose a specific drive, it’s likely because your computer is only configured to boot in BIOS mode.

How Do I Enable UEFI In MSI BIOS?

To enable UEFI in MSI BIOS, you will need to enter the BIOS settings and enable the UEFI Boot Mode. This can be done by going into the BIOS menu using the boot menu key and selecting the Boot tab.

Under the Boot tab, you will need to select the UEFI Boot Mode and then save and exit the BIOS. Once you have enabled UEFI Boot Mode, you will be able to boot into the UEFI BIOS.

MSI Boot Mode Select Greyed Out

If you’re having trouble booting up your laptop, it could be because the "Boot Mode Select" option is greyed out in the BIOS.

This setting controls whether your computer boots into Legacy mode or UEFI mode, and if it’s set to the wrong mode, it can prevent your machine from starting up properly.

In most cases, the Boot Mode Select option will be located in the "Boot" tab of the BIOS. If you don’t see it there, try looking in the "Advanced" tab or any other tabs that might be present.

Once you’ve found the setting, change it to match the mode that your operating system is using. For example, if you’re trying to install Windows 10, you’ll need to set the Boot Mode Select to UEFI in order to continue.

If you’re still having trouble booting up your laptop after changing the Boot Mode Select setting, it’s possible that your BIOS is simply too old to support UEFI mode.

In this case, you’ll need to update your BIOS to the latest version in order to proceed. Check MSI official website to see if there are any available BIOS updates, and then follow their instructions for installing the update.

With a recent BIOS in place, you should be able to boot into UEFI mode without any further issues.

If you want to disable CSM on MSI laptop, please follow the below steps:

  1. Enter BIOS setup by pressing "Del" key when MSI logo appears after powering on the computer.
  1. Go to "Boot" tab and enter "Boot Priority". Here you can set the boot priority of your devices. Please make sure that your USB drive is set as the first priority.
  1. Save and exit BIOS setup. Now your computer will boot from the USB drive without using CSM.
