Scenario: need to clone GPT HDD to SSD on Windows Server 2012
"I am a Windows Server 2012 64-bit user. I now have a GPT HDD on Windows Server
2012 and it works perfectly fine. But I would like to replace this UEFI GPT HDD with
an SSD while keeping the old data. Is there any way that I can clone GPT HDD to SSD
on Windows Server 2012 and boot from the SSD successfully?"
How to clone GPT HDD to SSD on Windows Server 2012 (R2)?
To clone UEFI disk to SSD on Windows Server 2012 (R2) and boot from the SSD after
clone, you need a disk cloning software. And AOMEI Partition Assistant
Server is such a cloning software that you can use to upgrade hard drive to SSD in a few simple steps. It can also clone GPT HDD to SSD easily.
Step1. Connect the SSD you prepared before, make sure it can be
detected by your Windows Explorer. Install and launch AOMEI Partition Assistant
Server, and you can see the basic situation of your hard drives. To clone GPT HDD to
SSD on Windows Server 2012 (R2), here you need to right click the GPT HDD, select Clone Disk on the pop out menu.
Step2. Then, you will move to the disk copy wizard. Here are
two copy methods, select the Clone Disk Quickly.
If you choose the sector by sector copy, AOMEI Partition Assistant will convert MBR
to GPT disk before copying.
Step3. Then, you can select the SSD as the destination disk. Don't
forget to check the box of “Optimize the performance of SSD”, which will align SSD
so that it will keep the best status after clone.
Step4. You can edit partition size on the SSD.
Step5. It will give you a note for how to boot from the cloned
drive. Read it, click Finish.
Step6. Then, you will back to the main interface, clickApply at the toolbar to submit the whole progress.
Problems of cloning GPT HDD to SSD on Windows Server 2012 (R2)
Using AOMEI Partition Assistant Server to clone GPT HDD to SSD Server 2012 (R2) is
such a simple thing. However, many users still have met some problems while
Clone GPT HDD to SSD failed
If your GPT HDD is larger than 2TB, you cannot clone the GPT HDD to SSD
successfully if the SSD is an MBR disk. MBR is a partition style that only supports
up to 2TB hard drive. If you insist to clone the over 2TB GPT hard drive to the MBR
SSD, it may be failed;
In other situation, if there are more than 4 primary partitions on the hard drive,
you cannot clone the GPT HDD to the MBR SSD. Cause MBR disk only supports up to 4
primary partitions or 3 primary partitions and one extended partition. While if you use
AOMEI Partition Assistant to clone more than 4 primary partitions GPT hard
drive to MBR SSD, it will convert the fourth and later partitions to
logical partitions autolatically.
Windows Server 2012 (R2) boot failure after cloning GPT HDD to SSD
You may also meet the problem that the Windows Server 2012 (R2) cannot boot
successfully after cloning GPT HDD to SSD. For this problem, you may need to make
sure if your SSD is MBR disk while your motherboard is the EFI/UEFI. The system on
the MBR disk should be boot from the legacy BIOS.
How to clone GPT HDD to MBR SSD Server 2012 (R2) successfully without boot failure
Fortunately, AOMEI Partition Assistant Server could help you if you meet the problems
> If you are going to clone GPT HDD to smaller SSD, you need to make sure that the
SSD is large enough to store the data on the GPT HDD. While if the used space on GPT
hard drive is larger than 2TB, you cannot clone it to MBR SSD directly. Good news is
that you can convert MBR disk to GPT on Windows Server 2012 (R2) first, then, clone
large hard drive to smaller SSD by Disk Copy feature.
> If the UEFI GPT disk has more than 4 primary partitions, you can tidy up the
data on the hard drive, or merge partitions, decrease the partitions on the HDD to
three primary partitions, then, clone GPT HDD to SSD on Server 2012 (R2). Or you can
make use of the function Quick Partition of
AOMEI Partition Assistant, which will convert the fourth partition and later
partitions to logical partitions while cloning. However, Quick Partition will delete all dataon
the hard drive, which means if you do not want tolose data,
backup hard drive first.
> If you want to boot from the MBR SSD after cloning, you need to make sure your
motherboard supports BIOS. Otherwise, you can convert MBR to GPT so that it can boot
Then, you can start to use it to clone UEFI GPT HDD to MBR SSD on Server 2012
AOMEI Partition Assistant Server should be the best disk cloning software that you
can use to clone GPT HDD to SSD on Windows Server 2012 (R2) with no boot failure no
matter the destination SSD is GPT or MBR disk. You can also mirror
MBR HDD to GPT HDD on Windows Server with AOMEI Partition Assistant Server.
Besides, it has many other features to manage your hard drive on Windows Server
2003/2008 (R2)/2012 (R2)/2016/2019. Such as extend
primary partition on Windows Server 2008, etc. It is worth to use.
