If you choose the Windows built-in tool, both two tools need to delete existing disk volumes. For avoiding data loss, trust us, you can choose the better one, Partition Master, to change partition style in 3 easy steps.

When vì You Need to Convert MBR khổng lồ GPT

Both MBR và GPT are the partition styles of Windows. Briefly speaking, the partition style is used lớn tell Windows how khổng lồ access the data on the disk. Generally, you can use your disk smoothly regardless of what the partition style is. But there vày exist some situations in which you need lớn convert MBR to lớn GPT or vice versa:

You want more partitions on your hard drive

MBR disks tư vấn only four partition table entries. That is khổng lồ say, it only allows users to create four primary partitions at most. If more partitions are wanted, a secondary structure known as an extended partition is necessary. 

Your hard drive is larger than 2TB

GPT (GUID Partition Table) is more robust và allows for volumes bigger than 2TB. Thus, if your hard drive is over 2TB, you may prefer the GPT partition style in order to fully use the disk space. (If the disk over 2TB uses the traditional MBR partitioning method, you can only use 2TB of storage at most.)

You want to perform system clone

As you may know, MBR and GPT disks use different boot mode. (MBR disks support BIOS & GPT disks support UEFI mode.) When you want to clone Windows or migrate OS, you need khổng lồ make sure both the source disk & the target disk have the same partition style lớn ensure you can boot your computer from the target disk smoothly.

3 Ways lớn Convert MBR to GPT Without Data Loss in Windows 11/10

As mentioned, there are three ways you can apply to lớn convert an MBR disk to GPT disk, including using Disk Management, DiskPart command, or third-party software.

Method 1. Change MBR to GPT with Reliable Partition Tool (Recommended)

If you use the Windows built-in utilities, be it Disk Management or diskPart, khổng lồ convert your MBR disk to lớn GPT disk, you need khổng lồ delete all the existing volume on your hard drive. Thus, if you want lớn convert MBR lớn GPT disk without losing data, you need to back up the whole disk in advance, which could be time-consuming since a disk always stores gigabytes of files.

Given that, you are recommended to lớn try the trustworthy partition tool - Partition Master. This software will help you convert an MBR disk to a GPT disk directly without losing data. With Partition Master, you don"t need khổng lồ delete the disk volumes as using Disk Management or DiskPart. All you need to vị is to lớn select the disk và choose "Convert lớn GPT".





Method 2. Convert MBR lớn GPT Disk with Disk Management

You need lớn delete all the volumes on your hard drive before the conversion, or you will see the "Convert to GPT Disk" is greyed out in Disk Management. Thus, if you have files existing on the disk you want to convert, back up all the files at the very beginning. Generally, you can back up a disk by copying files and folders manually, which will undoubtedly take a long time. If you want to make a backup effectively, you can use the miễn phí backup software - Todo Backup, which is much faster than copying and pasting files.

After you keep your data safe, you can now follow the steps below to convert your MBR disk to GPT disk in Disk Mangement.

Step 1. Right-click on "This PC", choose "Manage", then head khổng lồ "Disk Management".

Step 2. Right-click the volumes on your target disk & choose "Delete Volume..." (If you accidentally deleted a volume in Disk Management, you can recover the partition and the files on it referring lớn the linked article.

Step 3. When your disk becomes empty (shows as unallocated space), right-click your disk và choose "Convert lớn GPT Disk".


Now you have successfully converted the MBR disk to lớn GPT disk. In order to use the hard drive for data storage, you need to lớn create new volumes on the disk. (If you use the partition tool, you don"t need lớn perform these operations. Instead, you can use it directly after the conversion.)

Step 1. Right-click the unallocated space and choose "Create New Simple Volume..."

Step 2. Then you will see the "New Simple Volume Wizard" dialog box, click "Next" to lớn continue.

Step 3. Follow the wizard khổng lồ specify volume size, assign drive letter or path, and format the partition. Afterward, a new simple volume will be created. You can repeat the process khổng lồ create more partitions on the disk.

Step 4. You can copy the files you have backed up back to your disk according to your needs.


Method 3. Convert MBR Disk lớn GPT Disk Using DiskPart

DiskPart is a command-line utility in Windows that can be used to lớn manage disk or disk partitions. Thus, you can also apply this tool to lớn convert MBR to GPT disk. However, lượt thích using Disk Management, you are also required lớn delete the volumes on the disk before the conversion, which means data backup is also necessary if you prefer this method.

Step 1. Click the "Start" button and type cmd.

Step 2. Right-click "Command Prompt" & choose "Run as administrator".

Step 3. When you see a dialog box asking you for permission, click "Yes".

Step 5. After deleting the partitions on your disk, you can now convert MBR khổng lồ GPT:

list diskselect disk 1convert gptexit

The Bottom Line

Actually, the biggest difference between using the Windows built-in utilities và third-party software is whether lớn delete the disk volumes. As you can see from the details above, using partition software, which can serve as an MBR lớn GPT converter, is the easiest way to change an MBR disk to a GPT disk. Besides, the tool can also help you clone disks, merge partitions, shrink partitions, migrate OS... If you want khổng lồ convert a system disk from MBR to lớn GPT, using a convenient tool is recommended.
