About MBR and GPT
MBR and GPT are two distinct partitioning schemes that dictate how data is organized and stored on your disk. MBR, the older of the two, has been around since the early days of computing. It uses a 32-bit partition table and supports up to four primary partitions or three primary partitions and an extended partition with multiple logical partitions inside.
On the other hand, GPT is a more modern partitioning scheme that overcomes the limitations of MBR. It utilizes a 64-bit partition table, allowing for a virtually unlimited number of partitions, and supports disk capacities beyond 2TB. GPT also includes redundancy for critical partitioning data, making it more robust and reliable.
Why need to convert MBR to GPT?
There are several reasons why one might consider converting Windows 10 MBR to GPT:
1. Overcoming MBR limitations
As mentioned earlier, MBR has limitations when it comes to the number of partitions it can support and the maximum disk size.
If you find yourself needing to create more partitions or working with larger disks, converting to GPT becomes a necessity.
2. UEFI compatibility
GPT is a prerequisite for booting from a disk in UEFI (Unified Extensible Firmware Interface) mode. Many modern computers use UEFI firmware, and converting to GPT allows you to take advantage of its features, such as faster boot times and enhanced security.
3. Taking advantage of larger disks
As disk capacities continue to grow, GPT becomes the more viable option. Converting to GPT ensures that you can fully utilize the available space on your larger disks.
How to use DiskPart MBR to GPT?
Converting an MBR disk to GPT using DiskPart involves the following step-by-step process:
Step 1. Initiate the DiskPart window by pressing the “Windows + R” keys to access the Run dialog. Type “diskpart” in the box and hit “Enter”.
Step 2. Execute the subsequent commands one after the other:
List disk (This command provides a list of all connected disks on your PC).
Select disk # (# denotes the disk number of the target disk you wish to convert to GPT).
Clean (This command erases all partitions on the selected disk).
Convert gpt (This command transforms the selected disk into the GPT format).
Convert MBR to GPT with DiskPart alternative
While using DiskPart to convert MBR to GPT may seem straightforward, it can still be challenging for ordinary users due to the need to access the command prompt, which is not user-friendly for everyone. Additionally, its major drawback is the requirement to clear all data on the hard disk, and it cannot convert the system to GPT while Windows is running, as it lacks support for cleaning system disk data.
To address these issues and simplify the process, I recommend utilizing AOMEI Partition Assistant Professional as an excellent alternative to DiskPart. This robust MBR to GPT converter offers a more user-friendly experience. Notably, it enables you to convert between MBR and GPT without data loss. The conversion can be accomplished in just three simple steps.
Beyond its disk-to-GPT conversion capabilities, AOMEI Partition Assistant Professional provides a wide array of tools to efficiently manage disk partitions. Some of its useful features include the ability to allocate free space, shred files or folders securely, wipe hard drives, migrate Windows 10 to SSD, and even recover lost data, among others.
By opting for AOMEI Partition Assistant Professional, users can enjoy a seamless and comprehensive disk management solution that extends well beyond mere GPT conversion. It’s a powerful and user-friendly tool for effectively managing disk partitions and ensuring a smooth computing experience.
Let’s walk through the step-by-step process of using AOMEI Partition Assistant Professional to take the place of DiskPart MBR to GPT:
Step 1. Begin by installing and launching AOMEI Partition Assistant Professional. Once opened, choose the target disk you wish to convert, and then click on the “Convert” option located in the top toolbar. From the dropdown menu, select “Convert MBR/GPT.”
Step 2. Prior to proceeding, ensure that you have successfully converted Legacy BIOS to UEFI. Confirm the conversion by clicking “Yes”.
Step 3. Now, within the main interface of AOMEI Partition Assistant, click on “Apply” to initiate the conversion process.
Conclusion
Converting your disk from MBR to GPT is a significant decision that can enhance your storage capabilities and overall system performance.
With AOMEI’s step-by-step process, the conversion becomes relatively straightforward and keeps all data intact.
