GPT Disk Partition Magic Software: Migration, Resize, Convert and More

Merits of GPT Disk

GPT (GUID Partition Table) is a new style of partitioning on a physical hard disk, which was developed many years after MBR (Master Boot Record). So, it has many advantages that MBR doesn’t contain.

2 obvious merits of GPT Disk is that it supports up to 128 primary partitions, compared with MBR disk, which can only support up to 4 primary partitions or 3 primary partitions plus 1 extended partition. A GPT disk allows for a much larger partition size bigger than 2TB, which is the limitation for MBR disks.

Note: Windows can only boot from a GPT/MBR disk if the motherboard supports UEFI/Legacy

Disk Optimization with the best partition magic for GPT

Now, I will recommend you a partition magic software utility for GPT disks. The partition magic software is named AOMEI Partition Assistant Professional developed by AOMEI Tech Co., Ltd., This software is a professional partition tool. As its name suggests, is a good assistant for GPT disk partition. With this partition magic software, you can optimize GPT disk easily and safely. Moreover, other features like SSD 4K alignment and free space allocation are also contained. Read on to learn to use this powerful software for disk partitioning.

1. Resize GPT Partition

Resize partitionmeans to make a partition bigger or smaller than before. Thus, you can organize your files and data better. The following is a quick explanation of how to resize GPT partition with AOMEI Partition Assistant Pro.

Step 1. Select the partition you want to resize, right click and select “Resize Partition”.

Step 2. Drag the border leftwards to shrink the partition. Click “OK”.

Step 3. Back to the main screen, click “Apply” and “Proceed”. Thus, the partition would be perfectly resized without data loss.

2. Migrate OS to GPT Disk

You can use AOMEI Partition Assistant to migrate Windows OS to a new GPT disk when your hard disk is full or you simply want to enjoy faster speed provided by a new SSD.

Note: If you migrate OS from an MBR disk to a GPT disk, the boot mode should be converted from Legacy to UEFI.

Step 1. Click "Clone" >  “Migrate OS” on the wizards panel. Click “Next” in the pop-up window.

Step 2. Select disk space and click “Next”.

Step 3. Specify the size or the location of the partition being created.

Step 4. Read the note and click “Finish”.

Step 5. “Apply”. Thus, the operating system would be successfully migrated by this partition magic tool.

3. Convert GPT to MBR Disk without data loss

When it comes to GPT MBR conversion, many people will first think of the 2 Windows built-in utilities Disk Management and DiskPart. Indeed, with these 2 tools, you can convert between GPT and MBR. However, to start the conversion, you have to first delete all existing partitions on the hard disk which means you will either back up the disk or suffer from data loss. So, this time, by using the AOMEI product, you can avoid doing this.

Step 1. Select the GPT disk you want to convert, right click and click “Convert to MBR”.

Step 2. Click “OK” in the pop-up window.

Step 3. Click “Apply” to execute pending operations please.

Conclusion

In all, GPT disk partition is not a hard job once you find a proper partition magic for GPT. With the help of AOMEI Partition Assistant Professional, you can easily resize GPT partitions, convert MBR to GPT without data loss, and migrate OS to GPT disk in only a few steps.
