BIOS is the basic input/output system that controls communication between computer hardware and operating systems. BIOS is stored on a ROM chip located on the motherboard. The BIOS contains a set of instructions that the computer uses to perform basic operations, such as booting up.
UEFI (Unified Extensible Firmware Interface) is a newer type of BIOS that offers several advantages over Legacy BIOS. One key advantage of UEFI is that it provides a more user-friendly interface. BIOS screens are often text-based and difficult to navigate, whereas UEFI screens are typically graphical and easier to use. In addition, UEFI offers better support for large hard drives and long filenames. It can also boot faster than BIOS due to its smarter handling of driver loading. Finally, UEFI provides better security features, such as encrypting the boot process and requiring a password for BIOS settings changes. With so many advantages, it's no wonder that users want to change BIOS mode from Legacy to UEFI.
However, some computers still use Legacy BIOS, so it's still important to know the difference between the two types of BIOS. Follow this link to know more information about BIOS and UEFI.
There are several ways to check whether you are using Legacy or UEFI mode on your computer. One way is to check the System Information.
Step 1: Search "System Information" in the search bar and open it.
Step 2: Check your BIOS Mode.
There is more than one way to check whether you are using Legacy or UEFI. Follow this link if you are interested in other methods to check Windows using UEFI or Legacy.
Users may need to change the BIOS mode from Legacy to UEFI for various reasons. For example, they may be upgrading to a new operating system that requires UEFI, or they may want to take advantage of features that are only available in UEFI mode. In any case, changing the BIOS mode is not as difficult as users think.
In order to change the BIOS mode from legacy to UEFI, there are a few prerequisites that must be met.
- Windows version must be at least Windows 10 v1703.
- The MBR disk should not contain more than three partitions. If there are more than three partitions, you can merge or delete them.
- Turn off BitLocker before converting BIOS mode since it doesn't allow Windows to convert the drive from Legacy BIOS to UEFI.
- The operating system must be 64-bit.
- No dual boot.
Although you will not lose your data during conversion, we still recommend you back up your data first.
Converting a hard drive from MBR to GPT is necessary when changing BIOS mode from Legacy to UEFI. EaseUS Partition Master makes it easy to change convert drives from MBR to GPT with just a few clicks.
Step 1. Download and launch EaseUS Partition Master on your computer.
Step 2. Go to Disk Converter, select "Convert MBR to GPT" and click "Next" to continue.
Step 3. Select the target MBR disk that you tend to convert to GPT, and click "Convert" to start the conversion.
In addition, EaseUS Partition Master offers a number of other benefits.
- Migrate Windows 11 to a new SSD in one click.
- Resize/extend/shrink/create dynamic volume easily.
- Convert file system from FAT32 to NTFS.
As a result, it's the perfect tool for anyone who needs to change their BIOS mode or convert their hard drive.
You can also learn how to convert MBR to GPT by command prompt in our related article, which is more time-consuming.
Open the BIOS setting to choose UEFI as the boot mode. The general procedure is as follows, although some details may vary by the computer manufacturer.
Step 1: Turn on or restart your computer.
Step 2: When the computer manufacturer logo interface appears, long-press F2 to open the BIOS Setup. Generally speaking, most computers can enter the BIOS Setup by long-pressing F2, and some computers may enter through other keys, such as ESC, DEL, F12, etc.
Note: If you do not open the BIOS Setup in time at this time, Windows will load successfully, and you need to restart the computer to convert to BIOS mode.
Step 3: Use arrow keys to select the "Boot" tab.
Step 4: Select "UEFI" in the "UEFI/BIOS Boot Mode". Press Enter.
Step 5: Move to the "Save & Exit" tab and press Enter.
The article discusses how to change the BIOS mode from legacy to UEFI in Windows 10/11. It recommends using EaseUS Partition Master to convert MBR to GPT before changing the BIOS mode. This is because EaseUS Partition Master will ensure that the data on the hard drive is not lost during the MBR-to-GPT convention. Then convert Legacy BIOS to UEFI from the firmware settings screen for your motherboard.
