Summary:
Are you trying to find a free and simple way to convert MBR to GPT or GPT to MBR without losing data? Here you may try powerful CMD alternative software or apply Command Prompt to effectively convert MBR to GPT/GPT to MBR by simple steps with no data loss in Windows 10/8/7 with ease now.

Case 1. How to I change MBR to GPT?

"Hi there, do you know how can I change MBR to GPT without losing data in my Windows 10 computer? I got a second disk for extending storage capacity in my computer and I’m trying to convert it from MBR to GPT so that I can create more partitions for storing files and data.
Here is the issue that I’ve already saved some files inside the drive and will I lose my data while converting MBR to GPT?
"

Case 2. Can I convert the partition from GPT to MBR with no data loss?

"Can I convert GPT to MBR without losing any data in Windows 10? I just recently upgraded my computer to Windows 10 and I bought a second drive for upgrading my old hard drive. 
Then I added the drive to the computer and transferred some files and data to the disk. When I tried to move and install some useful software to the drive, the system won’t allow me to do so. It seems that those programs only support MBR disk and I must change the new disk into MBR so to complete the task. So if you have any ways to change the disk from GPT to MBR without losing files, please help me. Thank you.

How to easily convert GPT to MBR or MBR to GPT without losing data?

To convert MBR to GPT or GPT to MBR requires users to create data backups in advance. But if you have large number of data to transfer and backup to other drive, it would also take quite a long time.

So can you change MBR to GPT or convert GPT to MBR without losing any data? How? If you are trying to find a way or solution to complete the task, you are at the right place. Here in the below, you’ll find two methods for effectively helping you change disk partition table to MBR or GPT:

Method 1. Convert MBR to GPT or GPT to MBR with Command Prompt;
Method 2. Change disk to MBR/GPT without data loss by CMD alternative tool

Note: If you prefer a simple and effective way to change the disk partition table to MBR or GPT, CMD alternative software - EaseUS Partition Master is your best choice.

Let’s see how to perform GPT to MBR or MBR to GPT disk conversion in Windows 10/8/7 PCs now:

2. Type: diskpart.exe and hit Enter to open DiskPart window;
3. Type: list disk and hit Enter;
4. Type: select disk g (Replace g with the drive letter or your disk that you want to change it to MBR or GPT;)
5. Type: convert mbr or convert gpt and hit Enter;
Let the program to do the disk conversion task and then there you’ll get wanted partition table in your disk.
6. Type: exit to finish the task.

You can use the converted disk for saving data and install new programs or software so to meet your needs now.

Method 2. Change disk to MBR/GPT without data loss by CMD alternative tool
