When booting into Windows PE (WinPE) or Windows Setup, you can choose between UEFI and older BIOS modes. Following the installation of Windows, you may be able to swap between firmware modes by using theMBR2GPTtool. In general, install Windows using the more recent UEFI mode, rather than the older BIOS version, because it offers additional security features than the older BIOS mode. Alternatively, if you are booting from a network that only supports BIOS, you will have to boot into legacy BIOS mode.

To boot to UEFI or BIOS:

  1. Navigate to the firmware menus. You can employ any of the following methods:
  • To access the menus, start the computer and hit the manufacturer’s key on the keyboard. The following are often used keys: Esc, Delete, F1, F2, F10, F11, or F12. The most often used buttons on tablets are the volume up and down buttons (find more common keys and buttons). During startup, there is frequently a screen that contains the key’s description. If there isn’t one, or if the screen is moving too quickly for you to read it, go to the manufacturer’s website. Alternatively, if Windows has already been installed, click Power ()hold Shift while selecting Restart from either the Sign on screen or the Start menu. TroubleshootingAdvanced choices can be selected. UEFI Firmware Configuration
  1. Boot to a disk or network from the firmware menus while in UEFI or BIOS mode by selecting the following options: The command to use on the boot device menu is the one that identifies both the firmware mode as well as the device. For example, choose UEFI: USB Drive or BIOS: Network/LAN from the drop-down menu. It is possible to see different instructions for the same device. As an example, you can come across the termsUEFI USB Drive andBIOS USB Drive. Each command makes use of the same device and media, but it boots the PC in a different firmware configuration. Some gadgets only offer a single mode of operation (either UEFI or BIOS). Other devices will only enable you to boot into BIOS mode if you disable the UEFI security measures on the device manually. To turn off the security features, navigate to SecuritySecure Bootand turn off the function. Note Some older PCs (from the Windows 7 period or before) do support UEFI, however they require you to navigate to the boot file on your hard drive. Look for the option “Boot from file” in the firmware options, and then navigate to the folder EFIBOOTBOOTX64 to begin. EFI on a Windows PE or Windows Setup installation disc

UEFI and BIOS modes in WinPE

In order to identify which mode the device is in, you must query the registry. This may be accomplished using the command line: query in the reg System.CurrentControlSet.Control /v PEFirmwareType HKLMSystem.CurrentControlSet.Control

Return code Firmware mode

Make sure you boot into the right mode every time

The following are a handful of methods for ensuring that your computer boots into the correct firmware mode every time it is powered on.

Use preformatted hard drives, and use a method that doesn’t automatically format the drive.

In order to ensure that your drive boots into a certain mode, utilize drives that have been preformatted using the GPT file format for UEFI mode or the MBR file format for BIOS mode, as appropriate. When the installation begins, if the computer is booted into the incorrect mode, the Windows installation will be unsuccessful. This can be resolved by restarting the computer in the proper firmware mode.

Remove the UEFI or BIOS boot files

Delete the files that Windows PE or Windows Setup need to boot the computer into UEFI or BIOS mode if you only want it to boot into a certain mode. Remove the following files from your computer, depending on the boot mode you wish to use.

Boot only when in UEFI mode

Windows PE or Windows Setup media should have a bootmgrfile removed from the root of the media. In this case, the device will not be able to boot into BIOS mode.

Boot only when in BIOS mode

Windows PE or Windows Setup media should be removed from their respective root directories.

This stops the device from booting into the UEFI configuration. Create a bootable USB device using Windows PE.

How to Convert Legacy BIOS to UEFI in Windows 10 and 11

To convert a Legacy BIOS or Master Boot Record (MBR) to UEFI or GUID Partition Table in an earlier version of Windows, you were need to completely reinstall the whole operating system (Windows XP or before) (GPT). The introduction of MBR2GPT, a new and straightforward utility in Windows 10, has changed this. You can convert Legacy BIOS to UEFI in a matter of seconds by using only two instructions. Here’s how to change your Windows 10 operating system’s legacy BIOS to UEFI. In the case of Windows 11 users, you shouldn’t have to do anything because UEFI mode is already set on your system by default.

Why Convert Legacy BIOS to UEFI?

The reasons for switching from the Legacy BIOS to UEFI are obviously obvious, but just in case, here’s what you need know about the process. Both BIOS and UEFI serve the same purpose on your computer: they are both pieces of under-the-hood software that are incorporated into your motherboard chip and allow you to handle a variety of crucial low-level functions. Things like boot order, attached hardware, fan speeds, the physical lights on your computer, and system time may all be controlled by the BIOS/UEFI on your computer.

It’s quite effective.

When you use UEFI, you may expect quicker boot times (ostensibly), larger storage capacities, improved update mechanisms and driver support, and a 64-bit mode of operation (where BIOS is only 16-bit).

It’s worth noting that even newer PCs (including Windows 11) still refer to the motherboard software as the BIOS, despite the fact that it’s properly referred to as UEFI.

Things You Need to Know Before Converting Legacy BIOS to UEFI

Despite the fact that switching Legacy BIOS to UEFI in Windows 10 is straightforward, there are a few things you should be aware of and prepare for before beginning.

  1. During the conversion from Legacy BIOS to UEFI, there will be no data loss. (For further information, see the FAQs.) Please make a backup of your system as a precaution
  2. You should be using Windows 10 version 1703 or above. If you’re still not sure, hit Win+R, typewinver, and press Enter to run a test. On the second line, you should see “version 1703” or a version number that is greater.
  1. More than three partitions should not be present on the disk you are attempting to convert. You may either combine or erase the surplus partitions on the Windows 10 installation disk if you have more than three partitions on the device. (For further information, see the FAQs.)
  2. If you are encrypting your system using BitLocker, you must first decrypt the disk and then disable BitLocker protection before proceeding with the conversion procedure. The use of BitLocker security means that Windows 10 will not be able to convert your disk from Legacy BIOS to UEFI mode. It is possible that you may need to modify the firmware settings on your motherboard from Legacy BIOS to UEFI after converting. The technique for switching from one motherboard manufacturer to another will change depending on the manufacturer of your motherboard. Keep your motherboard’s user manual close at hand to make things easy for yourself.

If you want to learn more about the differences between UEFI and BIOS, we have a comprehensive reference on the subject.

Do I Need to Convert Legacy BIOS to UEFI in Windows 11?

Using Windows 11 indicates that your system has reached the last stage of transitioning from Legacy BIOS to UEFI configuration. Due to the fact that switching to a UEFI secure boot is a mandated Windows 11 compatibility requirement, this is the case. In Windows 11, there is no separate provisioning for Legacy BIOS, which is understandable. You may verify this by selecting “Windows Security” from the Start menu and ensuring that “Secure boot” is selected. Maintaining this setting is recommended by Microsoft in order to prevent malicious software from launching while the device is starting.

After the BIOS screen appears, select the Boot Options tab from the drop-down menu.

Windows UEFI should be displayed as the “first or only choice,” according to Microsoft. This is especially true for laptops manufactured by Dell, HP, and Lenovo. Some other manufacturers, on the other hand, may have retained both UEFI and Legacy/CSM functionality.

How to Check Whether You Are Using Legacy BIOS

The following steps will walk you through the process of switching from Legacy BIOS to UEFI in Windows 10. In the first instance, ensure that you are no longer utilizing Legacy BIOS. After all, if you are already using UEFI, there is no use in changing to it.

  1. To activate the built-in Drive Management tool, search for “Create and format hard disk partitions” in the Start menu and hit Enter. To right-click on the Windows installation disk, Disk 0, and select “Properties.”
  1. Go to the “Volumes” tab in the Properties Window to see the contents of the volume. If you notice “Master Boot Record (MBR)” next to “Partition style,” you are using the Legacy BIOS
  2. Otherwise, you are using the Modern BIOS. You don’t need to do anything further if, on the other hand, it reads “GUID Partition Table (GPT),” as seen in the figure below.

How to Convert Legacy BIOS to UEFI

It is possible to switch Legacy BIOS to UEFI if you’ve determined that you are running on Legacy BIOS and have backed up your machine.

  1. By hitting Win+X, you may access the Command Prompt from Windows’ advanced starting menu. To restart your computer, go to “Shut down or sign out” and press the “Restart” button while holding down the Shiftkey.
  1. The procedure described above will cause your system to reboot to the Advanced Startup screen. Go to “Troubleshoot -Advanced Options” and choose the “Command Prompt” option from the menu.
  1. Check the disk that you are attempting to convert for errors. Enter the command shown below into the text box.

If you see the message “Validation performed successfully,” continue to the next step. Any problems indicate that your disk or system may not be able to satisfy the conversion criteria. If you are experiencing difficulties validating at this stage, use the following command. We strongly advise you to use this add-on code in order to avoid data loss. the mbr2gpt/validate/allowFullOS command

  1. Following the validation of the disk, run the following command:

Windows 10 will begin the conversion process as soon as you press the Enter key, which will include importing all of the necessary UEFI boot files and GPT components, as well as updating the Boot Configuration Data.

  1. Restart your system and navigate to the motherboard firmware options panel, where you may convert the Legacy BIOS configuration to UEFI. The technique for switching from Legacy BIOS to UEFI is determined by the manufacturer of your motherboard. Consult the handbook for a detailed description of the procedures. Following the initial boot-up into Windows 10, you may check to see if you have been converted. Open the disk properties window from the Disk Management tool, and then select the “Volumes” tab, just as you did previously. You should notice the words “GUID Partition Table (GPT)” next to the words “Partition style” here.

How to Fix the MBR2GPT “Disk Layout Validation Failed” Error

While converting your hard drive from MBR to GPT, you may occasionally see the following error message: “MBR2GPT Disk layout validation failed for Disk,” where “Disk” refers to the boot disk you are currently using. There are two possible causes for this error: the presence of more than three partitions and a lack of sufficient space on the C drive, which serves as the boot disk.

  1. To resolve the “Disk Layout Validation Failed” problem, choose “Create and format hard drive partitions” from the search menu and verify that you do not have more than three partitions on the boot disk, Disk 0
  2. If you do, delete the partitions that were created. You will need to “merge and remove” some of these superfluous partition volumes in order to reduce the number of partitions to three or less in number. Make a backup of any vital data that is stored on the additional partitions.
  1. The second possible cause of the issue is that the Disk 0 disk does not have enough capacity to support an MBR to GPT conversion. In order to address this, you must reduce the amount of the file to somewhere between 200 MB and 2 GB.

Please keep in mind that if your device is already configured with a GPT configuration, these options will be grayed out.

Frequently Asked Questions

It is simple to transition a legacy BIOS to UEFI without affecting the data stored on the hard disk. This may be accomplished by including the /allowFullOSextension in the MBR2GPT conversion command. Even if the system is formatted, you will not lose any of your important data throughout the conversion process. It’s never a bad idea to keep a copy of your most critical files and folders on another computer, hard drive, USB drive, or the cloud just in case something goes wrong.

2. How do I resolve the “0x514; MBR2GPT failed to enable backup/restore privileges” error on Windows 10?

Although they were in onto the computer as administrator, some users have reported receiving a “administrator not found on the system” error while performing the MBR to GPT conversion on a command prompt. For best results, verify that you are using the elevated Command Prompt, which is the Administrator mode, while dealing with this issue. It may be accessed quickly and simply from the Start menu.

3. Can I go back to legacy BIOS from UEFI?

Even if you have your Windows 10/11 operating system installed in UEFI mode, it is possible to revert to a conventional BIOS configuration (although we strongly advise against doing so). The UEFI secure mode must be disabled on your Windows device before it can be reenabled. To do so, you must do a “advanced startup” on your Windows device and access the UEFI Firmware settings.

How to Change BIOS Mode from Legacy to UEFI Without Reinstalling Windows 10

Microsoft has included a handy function that was previously unavailable in prior versions of Windows, and even in certain older versions of Windows 10 (see below). TheMBR2GPTtool allows Windows 10 users to convert their Legacy BIOS to UEFI without having to rebuild the operating system. It is possible to execute the MBR2GPT utility from the Command Prompt, and with only two commands, you will have successfully transitioned from Legacy BIOS to UEFI.

Which Is Better: Legacy BIOS vs. UEFI

A piece of code known as the BIOS (Basic Input/Output System) is required by your CPU in order for it to boot up once you push the computer’s power button. BIOS was initially introduced many years ago and functioned well. BIOS, on the other hand, has several limitations. For example, the Master Boot Record (MBR) in the BIOS is used to establish a maximum partition capacity of 2.2 terabytes. Hardware advancements over the previous decade and a half necessitated the creation of new firmware. Then there was UEFI (Unified Extensible Firmware Interface).

UEFI is more reliable than BIOS and does away with the limitations of BIOS.

Getting Ready to Convert Legacy BIOS to UEFI

There are a few things you need to have in order before we can talk about switching from Legacy to UEFI BIOS.

Check Your BIOS Version

Check to see whether you’re currently using Legacy BIOS mode. There is nothing worse than going through the entire process just to discover that you were utilizing UEFI the entire time. Open the Disk Management application to find out what BIOS version you’re running on your computer. Open the Best match by searching forCreate and format hard drive partitionsin the Start Menu and clicking on it. Using this method, you will be sent to the Disk Management application. In the app, right-click on the disk on which Windows was installed and selectProperties from the context menu.

If you’re using BIOS, the disk partition style you’ll have is MBR (Master Boot Record).

In the Properties window, in theVolumestab section, you can see what type of disk partition is being used.

Check Your Windows Version

It is possible to use the MBR2GPT utility on Windows 10 versions 1703 and above. Prior to beginning the procedure, ensure that you have the correct version by searching forwinverin the Start Menu and selecting the Best match option from the results. The version on the second line will be shown in the new window that will open.

Legacy BIOS to UEFI Conversion Prerequisites

Given that you’ve confirmed that you’re utilizing the Legacy BIOS, there are a few additional items you should verify, and in some cases, make changes to your system.

  1. Assuming you’ve confirmed that you’re running the Legacy BIOS, there are a few more items you should check, and in some cases, make changes to your computer.

How to Change BIOS from Legacy to UEFI

After you’ve double-checked that everything is in working order, it’s time to start using the MBR2GPT utility.

  1. Start by searching for cmd in the Start Menu and then right-clicking and selectingRun as administrator. To be able to convert your disk, the MBR2GPT utility must first determine whether or not your disk meets the conversion requirements. Examine whether this is true by validating the disk with the following command:

The command Mbr2gpt /validate /disk:0 /allowFullOS will convert the disk 0 if it exists. If the disk you wish to convert does not exist, replace 0 with the proper disk number. If your disk does not satisfy the conditions for conversion, you will receive an error message. For example, when authenticating a USB device, the following error message was displayed.

  1. The following command should be used to commence conversion if the validation process was successful.

A command like Mbr2gpt/convert /disk:0 /allowFullOS will convert a file to GPT format. Allow the process to complete; it should take only a few seconds.

  1. Restart your computer and navigate to the firmware of your motherboard to make the necessary changes. For the most part, this process should just take a few seconds if you already know how to access the BIOS before beginning. In most circumstances, you’ll find an option to pick the Boot mode under the Boot tab/section in your firmware
  2. But, in certain cases, you may not see this choice at all.
  1. Start Windows by pressing the Windows key. Check to see if you were successful in converting the partition by repeating the procedure you performed previously. Then, in the Drive Management application, right-click on the converted disk, choose Properties Volume, and this time thePartition style should beGUID Partition Table (GPT)

Enjoy Your Modernized BIOS

UEFI is equipped with a plethora of features. Given that UEFI is used by the most majority of current computers, it’s only logical to wish to convert Legacy BIOS to UEFI. You’ve completed your task. However, you did not have to reinstall Windows, which was a blessing.

How to Change Legacy to UEFI without Reinstalling Windows 11,10, 8, 7?

Legacy firmware interfaces and UEFI firmware interfaces are two different types of computer firmware interfaces. They act as an intermediary between the operating system and the platform firmware. At the time of booting up a computer, the interface (either Legacy or UEFI) will initialize the hardware components and begin running the operating system that is installed on the disk. The distinction is not always clear to users, and some are unsure whether one is preferable to employ over the other.

  • The MBR disk is used by legacy BIOS, but the GPT hard drive is used by UEFI.
  • 2.
  • 3.
  • It has the potential to make the boot process significantly more secure by blocking the loading of UEFI drivers or operating system boot loaders that do not have an approved digital signature.
  • Switching from Legacy to UEFI can be a time-consuming process, but it is worthwhile if you are running 64-bit Windows 7/8/8.1/10.

Is it necessary to reinstall Windows for Legacy to UEFI switch?

As previously stated, the Legacy firmware option requires that Windows boot from an MBR disk, but the UEFI firmware setting needs that Windows start from a GPT boot disk. As a result, when moving the firmware setting from Legacy to UEFI, it is required to convert MBR to GPT. During the process of converting a drive from MBR to GPT, you will lose everything on the target disk, including the operating system and applications. As a result, in order to switch to UEFI mode, it is usually essential to reinstall Windows.

Once you have converted your Legacy BIOS to UEFI boot mode, you will be able to boot your computer from a Windows installation CD without any problems.

To convert a disk from MBR to GPT, type “diskpart” and use the command “list disk-select disk-clean- convert gpt” to do the conversion as seen in the screenshot below.

Otherwise, the disk will be corrupted. 4. At this point, you have the option of reinstalling Windows. If you attempt to install Windows without following these instructions, you will see the error message “Windows cannot be installed to this drive” after switching to UEFI mode in the BIOS settings.

How to change Legacy to UEFI without reinstalling Windows or losing data?

When using the first conventional approach, it is unavoidable to reinstall the operating system. Consequently, many customers are perplexed as to whether they can convert MBR to GPT without damaging data or if they can go from Legacy to UEFI without reinstalling Windows 10, 8, 7, or 10. Fortunately, there are certain professional and safe programs, such as AOMEI Partition Assistant Professional Edition, that allow you to convert a drive from MBR to GPT without removing partitions or losing data on Windows 11/10/8/7 and Windows XP/Vista without causing data loss (convert MBR and GPT without data loss in Server operating systems, theServer editioncan satisfy you).

  • Note:In order to minimize data loss due by faulty operation or certain events such as power failures, it is recommended that you back up important data in advance.
  • 1.
  • 2.
  • 3.
  • As soon as it is finished, you may enter the BIOS and change the boot mode from Legacy to UEFI.

How to Change Legacy to UEFI?

The procedure for enabling UEFI mode varies from machine to computer and is described below. You may use the following information to assist you with configuring yours. 1. Typically, when the computer first starts up, you must constantly press a certain key in order to access the EFI Setup menu. Normally, it isDel for desktop computers and F2 for laptop computers. Simply pressing Esc will suffice if you are unsure of which key to press. It will bring up the entire menu, from which you may choose BIOS Setup.

Finally, press F10 to save the changes and then press Esc to depart.

Due to the fact that you do not need to reinstall Windows 10, 8, or 7, as you can see, the complete procedure takes little time and effort.

How to Change Legacy to UEFI Without Reinstalling Windows 10

Modern motherboard (PC/Laptops) models now have support for the UEFI (Unified Extensible Firmware Interface), which is an alternative firmware interface to the conventional BIOS (Basic Input Output System) firmware interface. As a result, even without an operating system installed, the UEFI can handle hard drives with storage disk capacity of more than 2TB, and it provides superior performance, diagnostics, and repairs of computers. Only 64-bit versions of Windows 7, 8, 8.1, and 10 are supported, and since Windows 10 version 1607, you are unable to take advantage of the UEFI advantages (if your mainboard supports them) without having to reinstall Windows from scratch.

With the MBR2GPT.EXE command line utility, you can take use of the UEFI on a PC or laptop running Windows 10 version 1703 (Build 10.0.15063) or later without having to reinstall the operating system.

The following steps are only applicable if you have already installed Windows 10 on your PC. A circumstance in which the tutorial is applicable is one of the following:

  • It is possible that your system has been updated from an older operating system (e.g., Windows 7, 8, or 8.1) to Windows 10. Using the Legacy boot option in BIOS (CMOS) configuration, you have installed the Windows 10 operating system version 1703 (or a later version). You have successfully installed Windows 10, version 1703 (or later version), by booting from a Windows 10 boot media that was prepared for the MBR partition type.

How to Convert Windows 10 From Legacy BIOS to UEFI (Quick & Easy)

If you want to use an existing Windows 10 installation on a UEFI machine, you must first change the device’s legacy BIOS to a UEFI BIOS. Here’s a quick and easy method to accomplish it. Even if you purchased a new computer, the chances are good that it will be running on UEFI rather than the Legacy BIOS. In case you are unfamiliar with the term, UEFI is low-level software that runs immediately before the main operating system and connects the hardware, or more specifically, its firmware, with the operating system.

  1. Because the UEFI is pre-installed by the motherboard makers, you won’t have to deal with it or worry with it in any way.
  2. In the early days of computing, BIOS was mostly employed as low-level software.
  3. Among other things, it is unable to boot from high-capacity hard drives, it is unable to initialize numerous pieces of hardware at the same time, and it only supports 1 MB of storage space for its executable.
  4. In reality, UEFI has been implemented in practically all current systems in the last several years.
  5. Because UEFI is not backward compatible with traditional BIOS, there is a difficulty.
  6. Those who wish to do so must first convert Windows 10 from BIOS to UEFI, and then alter the motherboard’s configuration to UEFI mode.
  7. Simply follow the procedures exactly as they are written and you should be OK.

Check These Before Converting

Make certain that you satisfy all of the requirements listed below before proceeding. Any of the requirements that you did not satisfy must be addressed immediately and you must make every effort to meet all of them.

  • Microsoft Windows 10 should not be protected with BitLocker or any other type of encryption software. There should not be more than four partitions on the Windows 10 installation hard disk (include the installation partition). If you are utilizing a separate dedicated disk for Windows 10, such as an SSD, you should be OK
  • Otherwise, you should contact Microsoft. You should not be running two operating systems at the same time. You should be running Windows 10 1803 or a later version of Windows. Check the Windows operating system’s version

Please keep in mind that once the conversion process has begun, it cannot be stopped. Create a complete backup of your machine simply to be on the safe side.

Upon successful completion of the command, the message “Conversion finished successfully” appears.

Reboot the machine, boot into BIOS, and choose UEFI firmware as the boot device. After you’ve completed this step, Windows 10 will boot properly. In the event that you do not transition your firmware from BIOS to UEFI after converting, you will be unable to boot into your operating system.

In Case of Errors

If you see problems such as “cannot be converted” or “mbr2gpt failed,” it’s probable that one or more of the conditions specified above have not been satisfied by your computer. Alternatively, your system is incompatible with the BIOS to UEFI conversion owing to hardware or software constraints on your system.
