MBR is short for Master Boot Record and GPT is short for GUID Partitioning Table. Both of them are two different disk partition tables. As a matter of fact, there are two kinds of disk style, which are MBR disk and GPT disk. Nowadays, MBR disk is commonly used. But in some situations, the MBR disk still needs to be converted to GPT disk. For example:
 
Have done a wrong installation today, and have installed the OS with MBR, and now I can’t create a D drive with more than 2TB. I guess this is because we have MBR, and I want to convert this to GPT. Is there a free utility that can fix this without messing up my installation?
 
From above information, do you know how to help the user to convert to GPT disk Windows 10?
 

Why Need to Convert MBR to GPT Windows 10?

 
In the beginning, we will introduce why we need to convert MBR to GPT Windows 10.
 
1.To get more primary partitions.

An MBR disk only supports at most four primary partitions or three primary partitions and one extended partition while a GPT disk supports at most 128 primary partitions in Windows. So if you want to get more primary partitions, you need to convert MBR to GPT.
 
2.To make full use of unallocated space.
As is well known, MBR only supports the hard disk no larger than 2TB. If your hard disk is larger than 2TB, the left unallocated space will be wasted. So if you want to make full use of the unallocated space, you can convert the MBR disk to GPT disk without data loss.
 
Then we will introduce how to change MBR to GPT Windows 10 without data loss.
