A Guide to Using Three GPT to MBR Converters When dealing with hard disk partitions, you might need to convert the GUID Partition Table (GPT) to the Master Boot Record (MBR) format. Here's a brief guide on how to do this using three different : 1. **AOMEI Partition Assistant** - Download and install AOMEI Partition Assistant Professional or Ultimate edition. - Launch the program and select the GPT hard drive you want to convert. - Right-click the drive and choose "Convert GPT Disk to MBR Disk" option. - Confirm the operation in the warning window that appears, and follow the prompts. - Make sure to back up important data, as this process will delete all partitions. 2. ** Partition Master** - Acquire and install the trial version or purchase the full edition of Partition Master. - Open the software, and you'll see a list of disks and partitions. - Select the GPT disk you wish to convert, then click "Convert GPT Disk to MBR" in the top-right corner. - Review the settings before converting and click "Execute Operations." - You may need to restart your computer to complete the conversion. 3. **Disk Management (Built-in Windows tool)** - If you're using the Windows operating system, try the built-in Disk Management utility. - Press Win+X and choose "Disk Management." - Locate the GPT disk, right-click it, and select "Delete Volume" to remove all partitions (this will result in data loss). - With the disk now showing as unallocated space, right-click the empty area, choose "New Simple Volume," and follow the wizard to create a new MBR partition. Please note that before any disk conversion, backup all essential data, as these operations can lead to data loss. When converting system disks, ensure you understand potential compatibility and boot issues.

GPT to MBR: Can a GPT Disk Be Converted to MBR?

Read the full article: MBR vs GPT

When setting up a new disk in Windows 10 or 8.1, the system will ask you if you want to use MBR or GPT. As we know, MBR and GPT are two different ways to store partition information, both having their pros and cons.

Generally, GPT is considered the way of the future, aimed at overcoming limitations of MBR (including storage restrictions). However, many users still prefer MBR for its compatibility, and in certain cases, it's still necessary, as outlined below:

If you're installing a 32-bit version of Windows, you should choose MBR for your system disk. You should also choose MBR if you're still using an extremely old version of Windows. If you're running Windows XP or earlier, even on a 64-bit system, you must choose MBR for your system disk. You might see the error "Windows cannot be installed to this disk. The selected disk is of the GPT partition style" while installing Windows.

Technically, there's no answer to “GPT vs. MBR: which is better,” because the best partition style for you is always the one that fits your needs. If you're currently using GPT and need to convert GPT to MBR with one of the three solutions below, go for it.

To convert GPT to MBR without affecting internal data, you may consider using the preferred GPT to MBR conversion tool – tools Partition Master.

Method 1: Convert GPT to MBR Using a GPT to MBR Converter Tool (No Data Loss)

This partition magic tool can directly convert GPT disk to MBR disk without data loss (supporting hard drive with installed system). It eliminates the risks and difficulties of converting GPT to MBR, MBR to GPT, creating new partitions, or resizing partitions on the hard drive.

It allows all Windows 10/8/7/XP/Vista and Windows Server users to convert GPT disk to MBR without operating system while keeping data intact.

Follow these simple steps to convert GPT to MBR:

Step 1. Install and launch AOMEI Partition Assistant on your computer, and go to "Disk Conversion".

Step 2: Select “Convert GPT to MBR” and click “Next” to continue.

Step 3: Select the GPT disk that you want to convert to MBR, and click "Convert" to start the conversion.

When you can't boot into the operating system, you can still convert GPT to MBR without OS via a bootable media. The operation is the same as the steps above.

As a comprehensive disk and partition converter, you'll find that it supports conversion between GPT and MBR, and also handles:

• Convert Basic Disk to Dynamic or Dynamic Disk to Basic
• Convert FAT32 to NTFS
• Convert between Logical and Primary Disk

Unlike disk management and the command prompt, it doesn't require deleting volumes, so you won't lose data in the process. Therefore, it's the safest and most reliable method, and should be your first choice.

Method 2: Convert GPT to MBR Using Windows Disk Management

Before you proceed with the conversion, back up important data to an external hard drive first, and close any programs accessing the disk. Also, you need to have administrative privileges to do this in Windows. Disk Management is a default utility available for use on Windows 10/8.1/8/7/XP/Vista computers.

1. Open "Disk Management" as an administrator by navigating to "Control Panel" > "System and Security" > " Administrative Tools." Click "Computer Management" to open a new window.

Step 2: Under Storage, select Disk Management.

Step 3. To convert the disk from GPT to MBR, you need to delete all the volumes. Right-click on one and select Delete Volume. Do this for all partitions.

4. After deleting all partitions on the GPT disk, right-click the disk and select "Convert to MBR disk".

After converting a GPT disk to MBR, you can create partitions on the disk, which is now MBR, if you wish.

Method 3: Convert GPT to MBR Using the Command Prompt (UTF-8)

Also, this Diskpart method is based on deleting volumes and data. Before proceeding, back up your important data.

Step 1. Open Command Prompt as an administrator and type diskpart.

Step 2: Type list disk, and press Enter. Note the disk number that represents the GPT disk.

Step 3. If 1 is the GPT disk, type select disk 1, and press Enter.

Step 4: Type clean, and press Enter. This will erase everything on the drive.

5. Type convert mbr and press Enter.

Step 6. When you're done, type exit to close the command prompt.

Conclusions

After converting a GPT disk to an MBR disk, you'll need to restart your system. If your computer powers off, don't worry. To ensure bootability, you'll need to enter the BIOS. Tools like Partition Master make it easier and simpler to switch between GPT and MBR disks. It can assist you in accomplishing the task, even if you're not technically inclined. However, if you prefer using command lines, Diskpart might be a good option, but you'll need to delete all GPT volumes before starting.
