Master Boot Record (MBR) and GUID Partition Table (GPT) have different styles in partitioning. Due to its unique features, GPT has become popular. Hence, people started to convert MBR to GPT without data loss. Although people want to convert their MBR to GPT, they have a lot of queries regarding the advantages of GPT over MBR, conversion with the latest OS, and the details regarding the data. If you have the same doubt, you have come to the right place.
Here are some advantages of GPT:
GPT allows nearly 128 primary partitions, and that’s just four in MBR. However, MBR allows logical partitions.
GBT can support up to 18 EB, whereas MBR has maximum support of 2 TB. Although MBR can permit more than 2 TB disk space, windows could recognize only 2 TB in an MBR.
GPT has high-security standards while compared with MBR. If the partition table corrupts, the MBR disk could no longer be used. But, GPT has a backup GUID (Globally Unique Identifiers) partition, which allows recovering the partition table, even after the table is corrupted.
How To Convert MBR TO GPT
If you use Windows 10, here are some ways to convert MBR to GPT:
- Conversion of MBR to GPT with Disk Management
After opening the Disk Management tab, locate the disk that needs to be converted and right-click the disk. Delete the volumes. Then choose the disk and right-click and select Convert to GPT disk feature.
- Conversion of MBR to GPT
After choosing the number of disks to be converted to GPT, open the command prompt. On the command prompt:
Type diskpart, then press Enter
Type list disk, then press Enter
Type select disk (mention the number of the target disk next to select disk) and then press Enter
Type Clean then press Enter
Type convert to GPT
These two methods require the user to delete the partitions on the disk, which might cause data loss. If you don’t want to lose the data, follow the third method.
- Conversion of MBR to GPT without data loss
In this conversion method, you can use the non-destructive command prompt to convert MBR to GPT.
Press Win+R and open the command prompt. Run it as an administrator.
In the command prompt window, type gptgen.exe \\. \\ physicaldrive1
Now, you witness two files, primary.img and secondary.img. These files have the data to be written on the disk.
Now, type gptgen.exe -w \\. \\physicaldrive1 in the command line
That’s it… the conversion is over.
Using third-party tools, you can convert MBR to GPT without data loss. Some tools are available for free up to a specific limit. If those limits mentioned exceed, the users could buy the license for the conversion.
