“Hello, recently, I got a GPT SSD, and I want to transfer OS from MBR disk to GPT
SSD. Is that possible? Could I need toconvert GPT disk to MBR disk before
transferring? Is there any way that I can use to migrate OS MBR to GPT without
changing partition style?”
Why you want to migrate OS MBR to GPT?
Master boot record (MBR) disks use the standard BIOS partition table. GUID partition
table (GPT) disks use unified extensible firmware interface (UEFI). Besides, there
are many other differences between MBR and GPT disk:
MBR disk allows you to create up to 4 primary partitions. If you need more
partitions, you can only change one primary partition to extended partition,
then, create logical partitions on the extended partition. While you can have
more than 4 primary partitions on GPT disks.
MBR disk can only support up to 2 terabytes disk. That is why many people’s4 TB hard
drive only shows 2 TB. However, GPT disk supports more than 2 TB disk.
Because of GPT disk has more advantages compared with MBR disk, many users would
prefer GPT disk than MBR disk. On the other hand, SSD has many advantages than HDD -
It is more stable, and it has a better performance while working. Thus, part of
users would prefer to migrate OS from MBR disk to GPT SSD.
How to migrate OS from MBR disk to GPT SSD?
You may also have the problem “Is there anyway to move OS from MBR disk to GPT SSD?” like
the Scenario. Here, you can learn the way to migrate OS from MBR disk to GPT SSD
without changing partition style.
To migrate MBR OS to GPT SSD without changing partition style, you need to take use
of third party software. Considering the functions and price, AOMEI Partition Assistant should
be the high cost-effective one. What’s the important, it can directly transfer MBR
OS to GPT disk and it will create an EFI partition and
MSR partition so that the cloned GPT disk becomes bootable after the migration. Here
are some tips for you:
You need to make sure that your target GPT SSD should be bigger enough or at
least with the equal size to your MBR disk;
Make sure the target GPT disk is empty with no partitions and data on it,
otherwise, you need to delete all partitions on it;
Make sure your motherboard supports EFI or UEFI boot.
Step by step guide of migrate OS MBR to GPT SSD:
Step1. Install AOMEI Partition Assistant to your computer.
Connect your GPT SSD to your computer. Launch the program. It will show you the
basic environment of your hard drives like the following screen shot. Click Migrate
OS to SSD in the left pane.
Step2. Here you opened the Migrate OS to SSD/HDD wizard, clickNext.
Step3.Then, you need to select a partition or unallocated space on
the destination disk. Here is the GPT SSD you connected to your computer before.
Note: if you select a partition, all data on the partition will be
deleted, and you’d better copy
Step4. Here, you could modify the size, location, drive letter of
the partition on new disk. Click Next.
Step5. You will move to the page where gives you a note for how
to boot OS from SSD or HDD. Read it and remember it, click Finish.
Step6. Finally, you will back to the main interface of AOMEI
Partition Assistant. You can preview the operations in “Pending Operations”. If
there is no problem, click Apply to submit all.
The proceed will be finished under PreOS
After migrating OS from MBR disk to GPT SSD, please enter BIOS and change
boot setting to boot your computer from the GPT SSD.
AOMEI Partition Assistant Professional is a greatest partition manager for Windows
10/8/7/Vista/XP. You can use it to migrate OS from MBR disk to GPT SSD without
changing partition style. And you can use it to align SSD after migrate
MBR OS to GPT SSD. Besides, if you only need to convert between MBR and GPT disk,
AOMEI Partition Assistant allows you to convert
MBR GPT disk without losing data. What’s more, the AOMEI Partition Assistant
Server is designed for Windows Server OS. It should be the best service
for Windows users.
