GPT is short for GUID Partition Table, which is a standard for the layout of the partition table on a physical hard disk. It has the advantage that it allows for a maximum disk and partition size of 9.4 ZB (9.4*1021 bytes). So it can be used on some BIOS systems better compared with the limitations of MBR partition tables.

SSD is short for Solid State Disk. Compared to HDD, SSD works better if speed, noise, form factor, ruggedness, or fragmentation (technically part of speed) are important factors to you. What’s more, if you don’t mind the price and capacity of SSD, then you can consider to upgrade to SSD.

The Windows built-in disk management tool fails to do this. So I turn to the third-party software. I searched for several times and found that there are few software providing a function like "Migrate OS to SSD". At last, I chose AOMEI Partition Assistant. With the "Migrate OS to SSD Wizard" feature, you can easily clone GPT system disk to a new SSD easily.

Next, I would like to relate my experience:

Install and run AOMEI Partition Asssitant Professional. Then we can see the below picture:

PS.: You can also download its demo version to have a try at first.

Step 1. Click "Migrate OS to SSD or HDD" on the left side. And click "Next" in the pop-up windows.

Migrate Os To Ssd

Step 2. Select the unallocated disk (new SSD), then click "Next".

Select Space On Ssd

Step 3. Now we can set the parameters of the partition on the new SSD, including drive letter and partition size. All is done, click "Next".

Resize Partition

Step 4. Then, I think you’d better read the note before click "Finish".


Step 5. Last step: Click "Apply" button to clone system disk to SSD.


With just a few easy steps, I clone GPT system disk to a new SSD successfully with the help of AOMEI Partition Assistant Professional Edition. This is the magic power of it. I can also clone disk entirely to SSD using “Disk Copy Wizard” feature in deed.

Besides, AOMEI Partition Assistant has other powerful functions such as convert data disk between MBR and GPT styles, Windows To Go Creator, which can install Windows 8 to removable flash drive and so on. It runs perfectly under Windows 2000/XP/Vista/7/8/8.1, Small Business Server 2011/2003/2008, Windows home server 2011 and Windows Server 2003/2008/2012 (both 32bit and 64bit). And support MBR (under 2TB) and GPT (larger than 2TB) with 128 hard disks, with file system FAT, FAT32, NTFS and also EXT2, EXT3.
