Are you struggling to manage your hard drive partitions? Are you looking for the best way to change a partition style without losing data? If so, then this article is for you! We’ll discuss what GPT (GUID Partition Table) is and how you can safely and easily switch from MBR (Master Boot Record) to GPT without any data loss. Read on to find out more!

What is the GPT Partition Style?

The GPT partition style is a newer, more flexible way of organizing your computer’s storage. With GPT, you can have more than four primary partitions on a single drive, and you can use larger drives with more than 2TB of storage space.

If you’re using Windows 10, 8, or 7, your computer’s storage is probably already using the GPT partition style. That’s because GPT is required for drives larger than 2TB, and it’s also the recommended option for drives that are 4TB or larger.

If you’re using an older version of Windows, you might be using the MBR partition style. MBR can’t handle drives larger than 2TB, so if you have a new 3TB or 4TB drive, you’ll need to convert it to GPT before you can use it.

Converting from MBR to GPT is a fairly simple process, and it doesn’t require any special tools. You can do it right from within Windows Disk Management. Just keep in mind that converting a drive will delete all of the data on it, so make sure you have backups of any important files before you begin.

How to Change Your GPT Style Without Losing Data

If you’re running Windows, there’s a good chance your system drive is using the Master Boot Record (MBR) partition style. This was the standard for many years, but it’s been replaced by the newer GUID Partition Table (GPT) style.

GPT has a number of advantages over MBR, including support for larger drives and more robust error checking. If you’re ready to make the switch, here’s how to do it without losing any data.

Before we get started, it’s important to note that you can only change the partition style of an empty drive. So if you want to convert your current system drive, you’ll need to back up your data first. Once you’ve done that, you can proceed with the following steps:

1. Connect the empty drive to your computer and open Disk Management (search for it in the Start menu).

2. Right-click on the empty drive and select Initialize Disk.

3. In the window that appears, select GPT from the drop-down menu and click OK.

4. The drive will now be initialized as GPT and you can close Disk Management.

That’s all there is to it! You can now use this drive like any other and install Windows or whatever else you want on it.

What if You Don’t Have Enough Space for an EFI System Partition on Mac?

If you don’t have enough space for an EFI System Partition on your Mac, there are a few things you can do. One option is to use Disk Utility to create a new partition with the correct size and format. Another option is to use the dd command to create a new partition with the correct size and format. Finally, you can use the gpt command to create a new partition with the correct size and format.


Changing a partition style is an important task that should not be taken lightly. It is also possible to do it without losing any of your data, as long as you take the right steps. Make sure to back up your files before attempting this procedure and if in doubt seek professional help. With the above tips, you are now ready to change a partition style without any fear of losing valuable data!
