To Use the Gpt Partitioning System on a Hard Drive What Firmware Is Required

When you want to switch firmware blazon from the Basic Input/Output System (BIOS) to Unified Extensible Firmware Interface (UEFI) without modifying the electric current installation or deleting the information stored on the bulldoze, or yous plan to upgrade Windows 10 to Windows xi, you lot tin can convert the drive using a Principal Boot Record (MBR) to a GUID Partition Table (GPT) partition way using the "MBR2GPT" tool.

BIOS is a piece of code that resides on the motherboard that connects the hardware and software. This code has been around for a long time, and while it worked well, information technology was never designed for modern hardware, and it had many limitations, including limitations to partitions smaller than 2TB.

UEFI is the new firmware type designed to supervene upon the old BIOS mode. It introduces boosted features, including support for partitions larger than 2TB and faster startup, sleep, resume, and shutdown times. Also, it unlocks new security features available on Windows 11 and Windows 10. For case, "Secure Boot" is a feature that tin protect a device'south startup procedure from malicious programs, and now it's a prerequisite to install Windows eleven. "Device Guard" gives you more advanced controls for app access, and "Credential Guard" can help foreclose pass-the-hash attacks.

In this Windows 10 guide, nosotros volition walk you through the steps and information to use the Microsoft MBR2GPT control-line tool to convert a drive from MBR to GPT partition way, to switch from BIOS to UEFI mode on your device, and enable Secure Boot correctly.

Warning: This is a non-destructive procedure, only it's withal recommended to make a total fill-in of your PC before proceeding in case something goes incorrect and yous need to recover your setup.

How to catechumen a bulldoze from MBR to GPT on Windows x

Different older methods requiring a backup of your data and reinstalling Windows, the MBR2GPT tool makes information technology piece of cake to modify the partition style quickly. When using this tool, the conversion process adds the GPT components to the MBR sectionalisation without modifying the existing sectionalisation and maintaining the information untouched.

The best approach is switching to UEFI and performing a make clean install of Windows 11. All the same, if yous already have a Windows ten installation that you want to upgrade, y'all can convert the drive to change the organisation firmware settings properly. Otherwise, the device will no longer commencement correctly.

Check MBR or GPT partition style

Before making system changes, check the electric current settings to run into whether the organization is set to MBR or GPT using these steps:

1. Open up Start.
2. Search for Disk Management and click the superlative result to open the experience.

3. Correct-click the drive (where Windows 10 resides) and select the Backdrop option.

6. Click the Cancel button.

In one case you complete the steps, you can change the partitioning style on the computer.

Also, if you demand to change the partition, check your device manufacturer'due south support website to find out whether the hardware includes support for UEFI before using these instructions.

Convert MBR to GPT division style (offline)

To catechumen a drive using MBR to GPT on Windows 10, use these steps:

1. Open up Settings.
2. Click on Update & Security.
3. Click on Recovery.

4. Under the "Avant-garde startup" section, click the Restart now button.

8. Select your administrator account and sign in (if applicable).

9. Type the following command to validate the drive'south requirements and press Enter:

   mbr2gpt /validate

   Source: Windows Central

   Quick tip: The mbr2gpt.exe is located in the "System32" binder inside the "Windows" folder. If you want to meet all the available options, utilize the mbr2gpt /? command.

10. Blazon the following command to catechumen the bulldoze from MBR to GPT and press Enter:

    mbr2gpt /convert

    Source: Windows Central

11. Click the Close button.
12. Click the Turn off your PC option.

After you complete the steps, the tool will validate the drive and create an EFI system sectionalization (ESP). The procedure will also insert the UEFI kick files and GPT components into the sectionalisation. The tool will update the Kick Configuration Data (BCD), and the previous bulldoze alphabetic character will be added to the drive.

Catechumen MBR to GPT partition style (online)

It's ever recommended to utilise the MBR2GPT tool offline to avoid potential problems. Withal, you can too run it when the system is operational.

To catechumen a bulldoze from MBR to GPT on Windows 10, use these steps:

1. Open Start.
2. Search for Control Prompt, right-click the top result, and select the Run every bit administrator option.

3. Type the following control to validate the drive and press Enter:

   mbr2gpt /validate /allowFullOS

   Source: Windows Central

4. Type the following command to convert the drive to GPT and press Enter:

   mbr2gpt /convert /allowFullOS

   Source: Windows Central

Once you consummate the steps, the command-line tool will reduce the size of the principal partition and change it from MBR to GPT.

MBR2GPT return codes

If the processes are completed successfully, the return code would exist "0," just if the process fails, you may run across one of the eleven mistake codes:

Return code	Description
1	User canceled the conversion.
2	Internal fault.
3	Initialization error.
4	Invalid command-line parameters.
v	Mistake on the geometry and layout of the selected disk.
6	One or more volumes on the disk are encrypted.
vii	Geometry and layout of the disk don't meet requirements.
8	Fault while creating the EFI arrangement segmentation.
ix	Error installing boot files.
x	Error while applying GPT layout.
100	Successful conversion, but some kick configuration data didn't restore.

MBR2GPT important details

You lot can utilize the MBR2GPT tool on a traditional hard drive (HDD), solid-state drive (SSD), or an M.ii drive with virtually any version of Windows 10, merely you must run the tool from a Windows x (version 1703 or later) installation.

When dealing with a drive using file encryption with BitLocker, you must get-go suspend the encryption before following the outlined instructions.

While MBR-way drives can have up to four primary partitions, the bulldoze you desire to convert can't have more 3 partitions because one additional allocation is required to create the UEFI sectionalization.

Finally, Microsoft designed the tool to convert drives running Windows 8.ane, 7, or from an older version, simply you tin always upgrade the installation to the latest release of Windows x and so use the tool to convert from MBR to GPT.

How to change the firmware fashion from BIOS to UEFI

After converting the drive to the GPT style, the computer will no longer starting time until yous change the firmware blazon from BIOS to UEFI in the motherboard.

Typically, this process requires striking one of the function keys (F1, F2, F3, F10, or F12), Esc, or Delete primal as soon as y'all start the device. Yet, since these options are always dissimilar, information technology'south all-time to check your device manufacturer's back up website for more than specific details.

On the firmware interface, find the "Boot" menu, enable the UEFI pick, salvage the changes, so the calculator should start normally.

Also, if you plan to upgrade the device to Windows 11 while in the UEFI settings, open the kicking or security settings folio, make certain to enable the "Secure Boot" option, and exit the firmware saving the changes.

Check GPT sectionalization fashion

To confirm the device is using a GPT partitioning style, utilize these steps:

1. Open up Start.
2. Search for Deejay Management and click the top issue to open the app.

3. Right-click the master drive and select the Properties option.
