Why Migrate OS from MBR HDD to GPT SSD?

Speaking of HDD, you may think about SSD, and here is the advantages of SSD drive compared with HDD:

  • The read and write speed of SSD drive is faster than HDD.

  • Shorter boot time after migrating OS from HDD to SSD.

And following words will show you the superiority about GPT compared to MBR:

  • GPT disk is capable of very large size while MBR disk only supports up to 2TB partition size.

  • GPT disk allows a maximum of 128 primary partitions while MBR only allows four primary partitions at most.

Sometimes, you may want to migrate Windows 10 from MBR HDD to GPT SSD, What should you do and How? The following words will explain for you to perform system migration.

Check Before Migrating Windows 10 from MBR HDD to GPT SSD

If you want to migrate your Windows 10, or other Windows system, like Windows 8, 7, Vista, XP from MBR disk to GPT disk, you should pay attention to the following things:

1. Check if your Windows 10 System is 64-bit version.

Because only 64-bit version of Windows system can be installed on a UEFI-based disk. On the 32-bit system, you could not read, write, boot from the GPT disk. If other systems, make sure if it’s the 64-bit system as well. Here are the steps to check system versions:

Press Start > Settings > System > About, find the system type section, if it’s 64-bit operating system, x64-based processor or something like that, then it’s a 64-bit Windows 10. Or click System Info, then check System Type.

System Type

2. Make sure that your computer supports UEFI mode.

Here is a simple way to check your Windows version and UEFI Mode:

  • Press Win + R combination key to open Run dialog.

  • Then input msinfo32 and hit Enter.

System Information

You will see the system information including the System Type, BIOS Mode, etc. UEFI (at the BIOS Mode) means your computer supports GPT disk, and you will see the Secure Boot option in your BIOS settings if your computer supports UEFI. Otherwise, your current computer can only support MBR disk with Legacy mode.

By the way, you might want to convert disk between MBR and GPT without losing data for some reasons, it’s easy to do this conversion.

Migrate Windows 10 from MBR HDD to GPT SSD with AOMEI Backupper

How to migrate Windows 10 from MBR HDD to GPT SSD easily? The best Windows 10 migration tool - AOMEI Backupper Professional will do you a big favor. It is capable of migrate OS between MBR and GPT disks safely and easily, and ensure the cloned Windows 10 bootable. And it’s available for Windows Vista, XP, 7, 8, 8.1, 10(all editions, including 32-bit and 64-bit).

Before migrating, please download AOMEI Backupper 30 day free trial to demonstrate the cloning operation first (The Clone features in free trial can only be demonstrated, please upgrade to enjoy):

Here are the steps to migrate OS from MBR to GPT disk in Windows 10:

Step 1. Launch AOMEI Backupper. Select System Clone under Clone tab.

Choose System Clone

Step 2. The program will automatically select the Windows 10 OS, and please select the GPT SSD as destination location. Click Next to continue.

Choose Destination Partition

Tip: If the SSD is not empty, the program will prompt you all data on the destination will be deleted. Please backup important files or folders on the GPT SSD in advance before the Windows 10 migration.

Step 3. Check SSD Alignment to accelerate GPT SSD’s writing and reading speed and its lifespan. Then, click Start Clone to migrate Windows 10 from MBR HDD to GPT SSD safely.

Tip: Sector by sector clone is optional, if you checked it, the program will clone all the sectors on your system partition whether it is used or not, and it requires the GPT SSD is larger than MBR HDD. Meanwhile, it will cost much more time to clone.

The cost time will depend on the data size on your current disk. After cloning, to ensure clone MBR to GPT bootable, press a certain key during startup to enter BIOS(usually F2, F10, F12, ESC, or DEL, depending on your manufacturer), and then change the Boot Mode to UEFI in BIOS settings, then connect your GPT SSD and boot from it.

UEFI Boot Mode

Moreover, another feature could help you to clone MBR to GPT disk, that’s Disk Clone. It will clone everything on your MBR hard disk, including Windows operating system, settings, installed programs, personal files, to the GPT SSD. No Windows 10 OS and program reinstallation.


It’s not difficult for you to migrate Windows 10 from MBR HDD to GPT SSD with the help of AOMEI Backupper. This Windows 10 data migration tool is not only a Windows cloning software but also a backup and restore software, which offers you system backup, partition backup and entire hard drive backup, etc.
