How to from mbr to gpt. Solving the problem with GPT disks when installing Windows

Let's see how to convert MBR to GPT to change the hard drive partition style on your computer. Converting an MBR disk to GPT will allow you to switch to a modern standard, which has some advantages over the previous one.

Previously, when loading the Windows operating system, the BIOS used the master boot record - MBR (Master Boot Record), located on the computer's hard drive. The BIOS initializes the hardware, accesses the MBR, and transfers control of the computer to the operating system.

At this point in time, the outdated BIOS has been replaced with a new UEFI interface. One of the UEFI components is the GPT partition table (GUID Partition Table), located on the PC hard drive. Motherboard manufacturers are releasing equipment with the new UEFI bootloader, and accordingly, hard drive manufacturers are adapting to the new GTP standard.

Thanks to UEFI, the computer will be more secure (Secure Boot function). When using GPT, performance increases, there are more chances for this due to the fact that partition data is stored in different places on the disk, and not in one, as on a disk with an MBR partition table.

There are differences between GPT and MBR disks:

• disks with GPT support the creation of a huge number of partitions (up to 128), disks can be of any size, from existing hard drives;
• on disks with MBR there is a disk size limit of up to 2 TB; you cannot create more than 4 partitions;
• Only a 64-bit Windows operating system can be installed on a disk with a GPT partition table (starting from Windows Vista x64 SP1);
• With the UEFI BIOS interface, Windows can only be installed on a GPT disk.

If necessary, the user can change the MBR disk to GPT, or vice versa, convert . How to make a GPT disk from MBR?

You can convert a disk from MBR to GPT in several ways: using system tools and using third-party software. Conversion to GPT using the system means loss of data on the hard drive. All partitions will be deleted from the disk, all information will be erased.

To convert to GPT without data loss, you must use third-party programs (Paragon Hard Disk Manager, AOMEI Patition Assistant, Acronis Disk Director, MiniTool Partition Wizard, EaseUS Partition Master, etc.), which should be launched from bootable media (flash drive or CD/ DVD disc).

In this article we will look at methods using the tools of the Windows operating system: the Disk Management snap-in, using the command line during system installation, a simple method when installing Windows on a computer.

How to convert from MBR to GPT in Disk Management

This instruction is suitable if the computer has two hard drives; one of the drives must be converted to GPT. All actions take place in a running Windows operating system.

Follow these sequential steps:

1. Press the "Win" + "R" keys.
2. In the Run dialog box, enter the command: "diskmgmt.msc" (without quotes), and then click OK.
3. The “Disk Management” window will open, in which you need to right-click on the name of the desired disk (“Disk 0”, “Disk 1”, etc.).
4. The context menu item “Convert to GPT disk” will be inactive if there is data on the disk. All information must be deleted to enable disc conversion.

1. Right-click on the disk area and select “Delete Volume...”.
2. Click the drive name again and then click Convert to GPT Drive.

1. Do all the necessary steps.

After conversion, the hard drive has a GPT partition table. You can install 64-bit Windows OS on the disk.

How to convert from MBR to GPT via command line

When installing Windows on a computer, an error message appears in the window for selecting a disk for installing the operating system: “Windows cannot be installed on partition X of drive X. (Show details).”

To view the message, open a window in which you will see the entry: “Windows cannot be installed on this disk. The selected disk contains an MBR partition table. On an EFI system, Windows can only be installed on a GPT disk."

To solve the problem, you can use the system tool: the command line. We convert HDD disk from MBR to GPT via command line.

In the Windows installation window, press the keyboard keys “Shift” + “F10” (on some laptop models it may be “Shift” + “Fn” + “F10”).

In a command prompt window, run the Diskpart utility, which is designed to work with disks. Enter the commands sequentially, after entering each command, press the “Enter” key.

Diskpart

In the console window, enter the command to display a list of all drives on the computer:

List disk

Now you need to select the disk number. If your computer has multiple hard drives, look at the drive size to tell the drives apart.

Select disk X (X is the disk number)

Enter a command to clear the contents of the disk. After executing the command, all data and partitions on the disk will be deleted.

Then enter the command to convert the disk to GPT partition style:

Convert gpt

To exit the Diskpart application, enter the last command:

Close the command prompt.

The hard drive has been converted from MBR to GPT style.

Refresh the Windows installation window. Unallocated space will appear in the disk selection window. Click on the "Next" button. Windows Setup will automatically create the necessary partitions and then continue installing the operating system.

Convert MBR to GPT when installing Windows

Now let's see how to convert MBR tables to GPT when installing Windows 10.

After an error appears about the impossibility of installing Windows on a disk with MBR partitions, do the following:

Remove all partitions from your hard drive. Select the section and then click on the “Delete” button.

If your computer has another hard drive, leave it alone. Look at the disk number and the size of the partitions so as not to make mistakes when deleting partitions.

After deleting partitions, there will be unallocated space on the disk. Don't do anything else, just click on the "Next" button.

The Windows setup program will automatically convert the disk to GPT, create the necessary partitions, and continue installing the operating system on the computer.

Conclusions of the article

The Windows operating system supports converting hard disk partition tables from MBR to GPT by its own means: using the Disk Management snap-in, using the command line during system installation, or by simply deleting partitions during Windows installation.

Very often, when reinstalling the operating system or during other manipulations with it, the error “The disk has a GPT partition style” may appear.

Therefore, a completely logical question arises regarding how to change the style of GPT partitions on a laptop.

The above error usually looks like this.

It is in this very style that the solution to the problem lies.

But before you understand changing styles, you should understand why such an error occurs in the first place and what the concept of “GPT partition style” means.

Reason for the error

In general, the concept of “partition style” refers to how all the information is distributed on a computer’s hard drive. So, there are two types of these same styles - GPT and MBR.

Modern operating systems use the GPT partition style.

It became part of UEFI, that is, a new type of interface connecting hardware and the operating system itself. You may be more familiar with the concept of BIOS.

So, UEFI has replaced BIOS. Both UEFI and BIOS are responsible for ensuring that all components of the computer can work correctly and the equipment can accept the commands that are given to it.

But the problem is that in some cases you still need to return to the old MBR style. In particular, such cases arise when it is necessary to install an old operating system.

This is also true for laptops, especially those that are not very powerful. For powerful gaming laptops, changing the partition style makes no sense.

And the solution to the “The disk has a GPT partition style” error is to install a newer operating system.

And now, in fact, let’s move on to changing the style of GPT partitions on the laptop. There are several ways to do this.

Using standard Windows tools

Let's say right away that the solution to the problem of changing the partition style is to change the GPT to the MBR. This can be done very simply.

Important: When using this method, all data from the hard drive will be completely erased!

To change the style of partitions using standard Windows tools, you must do the following:

• On your keyboard, press the Shift and F10 buttons simultaneously. This will bring up the command line. On some laptop models you also need to press the Fn key.
  This should be done if the error that is shown in Figure 1 or at any other stage of working with the operating system occurs.
  If, at the stage where you are when the error occurs, the command line does not start after pressing the key combination Shift +F10 or Fn +Shift +F10, you should return to one stage. But in most cases it should run.
• At the command line, enter the command “list disk”. All this looks as shown in Figure 2. The command we need is underlined there with a red line.

• As you can see, after this a table of all the disks that are on the computer appears. Here we need to remember the disk numbers, which are circled in green circles in Figure 2.
  By the way, there will be an asterisk next to those disks that have the GPT style. In the example above, disk number 0 has just such an asterisk. By the way, you can use it to find out which disk should be converted.
• Next you need to enter the command “select disk a”, where “a” is the disk number (it is circled in green in Figure No. 2). In Figure 3 this command is shown with a red line. After entering this, the message “Disk a selected” will appear, as shown below.

• Now the selected disk needs to be cleaned. To do this, enter a command with a quite logical name - “clean”. This is shown in Figure 4.

• Now another command is entered with the same logical name - “convert mbr”. Actually, it is responsible for converting the partition style to MBR.

• Now we need to make a new partition on the same disk. Otherwise, there will simply be no partitions on the disk, and the data will not fit anywhere. Then the hard drive will simply become lifeless.
  To create a new partition, use the “create partition primary” command.

• Next, you should link the created partition to the entire system. This is also an important step, because, otherwise, the partition will exist on the disk, but the system simply will not see it. For the link, there is a command also with a logical name - “assign”.
  After this, you can exit the command line using the “exit” command.

That's it. Now the disk has been converted to MBR and you can try to install an operating system on it or perform other manipulations.

Through the installation window

There is a much simpler way than described above. It consists of selecting “Disk Settings” right in the installation window.

First, you need to close the window that says “The disk has a GPT partition style” and return to the window for selecting a disk for installation.

This method is suitable for cases where the hard drive capacity does not exceed 2.2 TB.

Interestingly, this is precisely the limitation that the MBR style has. Finding this inscription is very simple; its location is also shown in Figure No. 8.

Of course, before clicking on it, you need to select the desired disk or the desired partition; to do this, you just need to click on it in the list.

After clicking on this inscription, a window will appear with all partitions of the selected disk. They should simply be deleted and then created again, only with the MBR style.

This is also done very simply, and specifically, using the following sequence of actions:

• After clicking on “Disk Setup”, a set of commands will appear, which are shown in Figure 9. Among them, select the “Delete” command.

• In the window where the list of disks and partitions was previously located, the so-called Unallocated space on the disk will be present. It will be called that (an example of this is shown in Figure No. 10).
  We need to select it and click the “Next” button (located in the lower right corner). After this, the installed system itself will automatically select which style it needs and convert the system to this style.

Still, the first method is more reliable than this and there are several reasons for this, namely:

• The installed system may not convert the partition style correctly;
• In the first method, the user has the ability to control the entire conversion process;
• The command line can be called anywhere in the system installation or at any stage of other manipulations.

For these and other reasons, it is better to call the command line and convert partitions using standard system tools.

The command line may look scary, but there is nothing criminal in it.

If time and opportunities allow, you can completely interrupt all operations, go to a regular desktop and convert the style of partitions on the disk using one of the special programs designed for this.

After the release of Windows 7, a new type of hard drive partition was released, as a result of which users must perform a number of additional actions when reinstalling the operating system, namely, converting GPT to MBR, which must be performed precisely when installing Windows 7. An interesting fact is that you will be faced with the need You can also convert by performing other actions with the OS, but most often this happens during installation. We are going to walk you through the process of moving from GPT to MBR step by step using the most well-known methods and list the most suitable tools for this.

The average user may understand that he needs to change the disk conversion when installing Windows newer than version 7. Often the problem is the lack of UEFI on the computer (instead there is an outdated BIOS), which is necessary for the new version of the OS. The user encounters a problem when going to the disk partitioning screen, encountering a message that interferes with the further process. The message warns that a GPT disk is being used instead of the required MBR. In this situation, all that is available to you is the “OK” button and the menu for interacting with existing disks. The “Next” button will not be available to you in this situation. The opposite situation may also happen, in which the installation will require you not to use GPT, but MBR. Be that as it may, we will tell you about the process of changing the type of hard drive, and in the future, any of you will be able to convert Windows 7 disks in both directions, both from GPT to MBR and in the opposite direction.

Conversion during Windows installation via command line

The command line is an integrated tool in any Windows that can organize local disks and change GPT to MBR. It is capable of converting GPT to MBR and vice versa, provided that the disk to be converted is not partitioned.

The usage scheme is as follows:

1. Click “Start” > enter “Command Prompt” and run it with administrator privileges;
2. Enter “diskpart” and press “Enter”;
3. Enter “list disk” and press “Enter”;
4. Enter “select disk N” and press “Enter”. Instead of “N” you must put the number of the disk to be changed (for example, “Disk 0”);
5. Enter “clean” and press “Enter” to delete partitions or volumes on the disk that was selected;
6. Enter “convert mbr” and press “Enter”, after which the change from GPT to MBR will be completed.

The method is quite controversial because it entails deleting all information on the media. That is why, before the conversion procedure, we strongly recommend that you reserve the information you need on removable media and then restore it.

Convert using Windows Disk Management

Disk Management is a tool integrated into Windows 10 that allows you to make changes (create, delete, increase, shrink) partitions, convert them to GPT or MBR.

Here's how to use it:

Programs for conversion without data loss

There are also a number of utilities that allow you to convert disks without losing data. To use them, you do not need to delete all partitions. But it is worth saying that the possibility that the data will be erased is still present and you should be prepared for this, since this possibility is present during all operations with a partition and/or disk. In this regard, we highly recommend that you back up the necessary data on removable media before using any of the programs.
So, if you have made all the necessary preparations, then let's look at three programs that are most suitable for manipulating disks.

AOMEI Partition Assistant Standard Edition

A wonderful and freely distributed utility that allows you to manipulate media. With its help, in a couple of clicks you can change the file system, partition size, cloning, etc. And most importantly, most operations are performed while saving your data (this is the main advantage over standard system utilities).

Unfortunately, just recently the ability to convert MBR to GPT starting from version 7 of the utility became paid (it is free in version 6.6, so you can install it as an option).

There is no need to dwell on how to download and install the program; everything is standard here. Having launched the utility, in its start window you will see information about which of your partitions are converted to GPT and which to MBR (see picture).

For example, let's look at the MBR to GPT conversion.

Notes!

If you need to convert the system disk (that is, the disk on which Windows was installed and from which you are currently working), you will not be able to achieve this in the usual way. Under these circumstances you need:

EaseUS free Partition Master

Another program for converting MBR to GPT is EaseUS free Partition Master. The program, just like the previous one, will save all your data, it is a little easier to learn for users and regularly receives updates from the publisher.

If you decide to opt for this utility, then here is the procedure for completing the conversion using it:

Paragon Hard Disk Manager

The Paragon Hard Disk Manager program operates exclusively in the operating system itself, therefore, you should not remove the OS by simply formatting the system partition. Convert the disk first, and then you can perform the necessary actions.
The utility is paid, but there is a trial version, which is basically enough for you. To download the program, simply register on the official website, the download link will be sent to your email. All that remains is to download and install it.

1. After launching the application, in the dialog box, select the GPT disk to be edited with one click, and at the top of the window click “Hard Disk”. In the contextual one - “Convert to basic MBR disk”, confirm the performed actions by clicking on the green checkmark.
2. In the window that appears, click “Convert”.
3. At the end of the process of transition from GPT to MBR, Paragon will display the “All operations completed” window.
4. After that, close the program and continue to use your PC.

Video: converting GPT disk to MBR

So which is better GPT or MBR? The answer to this question cannot be known without taking into account the requirements that apply to each technology in a particular case. MBR and GPT perform the same function - storing information about the disk structure and ensuring the operating system boots. In many ways, these technologies are similar, but there are also differences between them. Currently, MBR is supported by almost all operating systems, however, GPT has many advanced features. In addition, in some cases it is impossible for the user to do without installing GPT, for example, when using disks with a capacity of more than 2 TB.
If you have decided which technology you will use and realized that you need conversion, then here is a video that shows this entire process without data loss using the Paragon Hard Disk Manager program.

Found a typo? Select the text and press Ctrl + Enter

Quite often, users are faced with what they think is a big problem when it becomes necessary to convert the partition style from GPT to MBR. This may be due to many factors, among which the main one is the impossibility of installing some OSes in such partitions and compatibility with the new standard of the UEFI primary input/output system, which replaced the BIOS. There are several ways to convert partitions with more modern GPT markup to MBR and vice versa. But you can replace one style with another either with or without saving the data. Let's consider each of these options, since some steps may be useful even when installing the operating system on your computer for the first time or reinstalling it.

Difference between GPT and MBR styles

First, let's look at what exactly is the difference between these styles, and what each of them can be used for. The MBR (with boot record) partitioning is considered to be obsolete today, and has been replaced by the new GPT style. This type of partitioning on a hard drive is mandatory if the hard drive has a capacity of 2 TB or more. But to ensure correct work with such partitions and use of their full capacity, you need an updated version of the primary system, designated UEFI.

If MBR and BIOS are used, installing disks of this size on modern computers becomes simply pointless, since the BIOS does not support them, and if the UEFI mode is disabled, despite the media being detected in the primary system, the full disk space will be inaccessible. So, think a hundred times to what extent it is advisable to perform the actions described below.

Problems with operating systems

But the main problem is that outdated operating systems like Windows 7, which are still popular among many users, are not installed on partitions with GPT partitions, and do not even support the main UEFI operating mode. To carry out the installation, some users suggest disabling UEFI to use Legacy mode, as for a regular BIOS. On the other hand, if you purchase a new computer with the primary UEFI system already installed instead of the BIOS, G8 will not install with UEFI disabled either. Thus, we get two mutually exclusive factors. However, you can get around such obstacles using fairly simple methods, but you will have to work a little.

Conversion during Windows installation

First of all, let's focus on whether to install Windows or vice versa. In this case, the safety of the data on the disk is not guaranteed, since it will have to be formatted during the installation of the operating system. Despite the fact that these questions are only indirectly related to the main topic, it does not hurt to have knowledge on them.

At one stage after starting the installation process, the installer of the same “seven” displays a message stating that installation to the selected partition is impossible. In this case, the simplest solution is to delete absolutely all partitions on the disk and install Windows in the unallocated area.

You can also create a system partition for Windows yourself, and use the rest of the space for logical volumes. However, this will not automatically create a special reserved partition, which will affect the fault tolerance of the installed OS. The installation section will be automatically converted to the desired style.

Thus, if we are talking about how to change GPT to MBR, you need to use the command line tools (Shift + F10), in which the following commands are written, shown in the image above. After this, you can continue installing the system as usual.

How to change GPT to MBR: creating a bootable USB flash drive and selecting the start mode of the primary I/O system

Now let's go back to the starting point and determine the steps that may be required to convert styles from an already installed OS (for example, Windows 8/1). To do this, you will initially need to create a bootable USB flash drive with Hard Disk Manager version 15 from Paragon or a similar utility from Acronis (Disk Director). The media itself is simply created in a small Rufus application, and then placed first among boot devices.

Immediately in the settings of the primary system, you must immediately change the boot mode (Boot Mode) from UEFI to Legacy and disable Secure Boot. Such actions are only necessary if a regular bootable flash drive was created for MBR, and not EFI.

Partition conversion process

Now you need to boot from the created media. The essence of how to change the GPT style to MBR comes down to deleting all partitions in the program at the first stage, including those reserved by the system for recovery, leaving only the one on which the installed OS is located.

When deleting backup partitions, in the confirmation window, be sure to check the box to not request a volume label next time. Once these steps are completed, only the base GPT partition will remain. How to convert GPT to MBR at this stage?

To do this, you need to select the appropriate conversion item in the additional menu via RMB and confirm your actions. Since the operation will be transferred to the deferred category (as well as in other utilities like Acronis Disk Director), you need to click the “Apply” button, after which the conversion process will start.

Additional steps to create a backup partition

But that's not all. The fact is that after changing the style, the system simply will not boot, and besides, you need to create a backup partition for it with boot data of the installed OS itself with a volume of about 300 MB. This can be done through the RMB menu on an unallocated area and selecting the option to create a partition, after which you will need to specify its size and file system (NTFS), and after completing operations through the same menu, make the partition active.

Creating a configuration to boot the installed system

At the final stage, it remains to create a configuration so that the same “eight” could boot with the new partition style without problems. In this case, you need to restart the computer, boot from the installation media and call the command console. In it you need to determine which letter is assigned to the active boot partition. To do this, first enter and then - lis dis, which will display all active sections.

We remember the drive letter on which the system is installed, execute the exit command for the main tool, and after it enter the line bcdboot N:\Windows, where N is the letter of the system partition. After that, we reboot the computer again, but in normal mode, setting the UEFI boot to normal, and rejoice. You can check the changed style directly through the partition properties on the volume tab.

Windows Tools

In principle, speaking of how to change GPT to MBR, one of the solutions for running OSes can be their own tool in the form of the disk management toolkit (diskmgmt.msc).

Here, too, you can delete unnecessary sections, and then through the RMB menu on the unallocated space, select the conversion from one style to another. True, the only and main limitation is that such actions can only be performed for non-system disks or logical partitions, that is, it will be impossible to change the style of a Windows disk directly in the system.

Changing section style using third-party programs

And finally, a few more words about how to change GPT to MBR. As more convenient tools than those available in Windows, you can use special disk programs from Acronis, AOMEI, Paragon and other developers. The operations performed, in general, do not differ much from those just described for Windows tools and boil down to converting unallocated space into the selected style. However, the conversion is much faster and more efficient. The interface of such programs is very similar to the Windows disk management section, but some operations (for example, redistributing disk space) are performed much easier by using the most common fader (slider), by moving which you can select the required size of each partition.

Brief summary

That's all briefly about style conversion. As is already clear, if we are talking about performing transformations while preserving a working system and data that may be located in the system partition, you need to use exclusively disk utilities with the preliminary creation of bootable media. If saving the information is not required, you can convert it at the stage of reinstalling the OS, using Windows tools, or using third-party programs. But you won’t be able to change the main partition in a running system even with their help, no matter how much you might want it. It will be impossible to remove it!

Connect the Windows 7 bootable USB flash drive to the USB 2.0 port (black), when connecting the flash drive to the USB 3.0 port (blue), an error may occur, since the Windows 7 installer does not have USB 3.0 drivers.

As usual, at the beginning of the article, we publish a letter from a reader of our site.

Hello admin, I ask for your advice! I bought a powerful system unit. The BIOS on a new computer is, you guessed it, UEFI. I installed the Windows 7 64-bit operating system myself, but ran into a problem. My hard drive has a capacity of 3 TB and after installing the operating system, 745 GB remained unallocated on it. After a short search for information on the Internet, I realized that this is due to the fact that my hard drive has the most common and already outdated type of partition table layout, MBR, which does not see all the space on a hard drive larger than 2 TB. This means that my hard drive needs to be converted to the new GPT partition table format, which, by the way, has many other advantages over MBR. This is where my adventures began, judging by numerous posts on the Internet, I’m not the only one.

On one very authoritative resource they offered me a helping hand with such an “encouraging” message “ None of the editions of Windows 7, unlike Windows 8, support installation on drives with GPT contents" In my case, I just need to buy an additional SSD solid-state drive and install the Windows 7 64-bit operating system on it, then convert my second 3 TB hard drive to GPT and use it for file storage.

Administrator's note: This can only be done if all sections have been deleted on it and, accordingly, there is no information.

Installed?

Now run the following command:

xcopy I:\*.* F:\ /e /f /h (where I is the drive letter of the connected ISO image with Windows 7, and F is the drive letter of the flash drive). The Windows 7 installation files are copied to a flash drive, which takes 3-5 minutes.

There are a few commands left:

xcopy F:\efi\microsoft\*.* /e /f /h F:\efi\

xcopy C:\Windows\boot\efi\bootmgfw.efi F:\efi\boot\bootx64.efi(where F is the drive letter of the flash drive)

We answer the question by pressing on the keyboard (F).
And the last one:
bootsect /nt60 F: (where F is the drive letter of the flash drive) (the file is located F:\boot\bootsect)
Our UEFI bootable USB flash drive Windows 7 64-bit ready!

Note: If you enter the command bootsect/nt60 the following error will appear "bootsect" is not an internal or external command, executable program or batch file, then change the command to this I:\Boot\bootsect.exe /nt60 F:(where I is the drive letter of the connected ISO image with Windows 7, and F is the drive letter of the flash drive).

To install Windows 7 on a GPT disk, we need to properly configure our UEFI BIOS.

When loading, press Delete or F2 and enter the UEFI BIOS. Click Advanced (F7).

Then go to the menu CSM (Compatibility Support Module)

And set the Launch CSM position to Enabled.

Boot Device Options– set to UEFI Only

Click on the arrow and exit the menu - set the Windows UEFI mode parameter and exit back.

Download priority

Boot option No. 1 – select our flash drive

Boot option No. 2 – select our hard drive.

That's all the settings. Press F10, this saves the changes we made to the UEFI BIOS.

In general, in UEFI BIOS you can change the boot priority in the initial window. In the initial phase of booting the computer, press Delete or F2, enter the UEFI BIOS, select the boot menu (F8),

Then we select our flash drive, it boots from the flash drive.

We boot into the Windows 7 installation program. Everything is as usual. Next.

Install. We accept the license agreement. Full installation (additional options).

In this window, we do not pay attention to existing sections.

We call the command line, in it we will convert our hard drive to the GPT standard, all partitions and data on the disk will be deleted. Press Shift + F10 on the keyboard. On the command line, enter the commands sequentially:

click Update.
