Nowadays, GPT partitioning is widely used in many computer systems. Compared with MBR, GPT has more advantages than it. Although GPT doesn’t have limitation to number of partitions, Windows can support at most 128 partitions. We can divide GPT disk into at most 128 partitions while MBR can be divided into at most 4 primary partitions or 3 primary partitions and 1 extended partition. We know that GPT is short for GUID Partition Table. GUID Partition Table has a backup of itself which is put at the end of hard disk, so, when one partition table is damaged, we can recover it with the other one. But, MBR doesn’t have this feature. What’s more, GUID Partition Table can support at most 18 EB disk while MBR partition table can support at most 2 TB disk. All in all, GPT has more advantages than MBR. Users may need to convert MBR to GPT without data loss right now, if they use MBR disk.
The first way for users to change disk type is to make use of DM (Disk Management) in “My Computer” of Windows. The steps of how to achieve converting MBR to GPT with Disk Management is as follows: users can right click “My Computer” and choose “Disk Management” in “Manage”; users will see that all disks of their computer are in “Disk Management” interface; they may right click a MBR disk and then choose “Convert to GPT Disk” to achieve conversion.
However, if users want to convert MBR to GPT without data loss by using the first way, they may not avoid data loss. During the converting process, users’ important data may be lost. So, in view of data safety, users had better backup data before they use this small tool.
The second way to achieve disk conversion is to use third party tool. If users want to convert MBR to GPT without data loss, they are intensely advised to use the “Convert MBR Disk to GPT Disk” function of MiniTool Partition Wizard. This software has a built-in function to prevent data from being lost. Users can convert disk without worrying about losing data. But in view of data safety, we’d like to suggest users backup data first.
To successfully convert MBR to GPT without data loss, users just need to choose a MBR disk and click “Convert MBR Disk to GPT Disk” from the left action panel in the main interface of this partition magic and then finish all operations according to the software prompts.
This article has introduced two ways for users to achieve disk conversion. If users are more interested in how to convert MBR to GPT without data loss by using MniTool Partition Wizard, they can click here to get this partition magic.
