Copy or move MBR from a disk To another disk

copy or move mbr from disk to another.

Can I copy the MBR from one disk to another?

"Hi, guys, I have a question and I need your help. I actually have 2 SATA hard drives: one is the primary hard drive (120GB), which contains MBR, startup files, and Windows 10 SP2; and the other is the second hard drive (200 GB), which contains Windows 10 SP2".

"On my 120 GB hard drive is my old Windows 10 SP2 installation, and they bought a new 200 GB hard drive (the second one). I have installed Windows 10 SP2 on the new hard drive. By the way, my boot files (boot.ini / ntldr / ...) and MBR are still on my first hard drive. I tried to copy the MBR to a new disk but failed. Therefore, anyone knows how to successfully copy or move MBR from one disk to another Windows 10".

Why copy or move MBR from a disk To another disk?

MBR (Master Boot Record) is the boot sector at the beginning of the computer hard disk, which contains key information about all partitions, including the file system , Partition size, organization, etc. In addition, it also contains executable code to connect the volume boot record (VBR) of each partition. When fully executed by the BIOS, this code transfers control to the startup program stored in the boot partition to load the operating system and ensure a successful boot.

If you fail to copy the MBR from one disk to another as described above, you will not be able to boot properly from the new drive. Copying only the MBR is not easy; therefore, you can choose to clone the entire disk containing the master boot record to another disk. As long as you use a reliable cloning tool, it will ensure you a smooth start.

To copy MBR from one disk to another in Windows 10/8/7/XP/Vista, you can use AOMEI Partition Assistant Pro. Its "disk cloning" function allows you to copy the entire disk (all partitions, including the MBR boot drive) to another disk. Its "partition clone" allows you to copy only the MBR boot partition to a new disk.

In addition, the software can also help you repair the MBR when it is damaged. Next, we will guide you how to clone the master boot record from one disk to another using the "clone disk" function. You can download the demo version for a free trial.

Step 1 . Install and run this software on a Windows computer. Right-click the MBR system disk and select "Clone Disk".

Step 2. Choose a disc copy method and click "Next" to continue.  

? Fast disk cloning: Just copy the used disk space to another disk, and you can also adjust the partition size during the cloning process. Using this method, you can clone a large disk to a smaller disk.

? Sector-by-sector cloning: Copy all sectors of a disk to another disk, regardless of whether it is used or not.

Step 3. In the window, you need to select a target disk that contains all the data in the source disk. If the target disk is an SSD disk, you can check the "Optimize SSD performance" option to optimize the SSD read and write speed. Then click "Next".

Step 4. You will receive the target disk data If you have already backed up important data in advance, please click "Yes" to continue.

Step 5, here you can change the partition size according to your The preferences are on the target disk. Then click "OK" to continue.

Step 6. Then you will receive an instruction on how to operate. After the process is complete, successfully boot the operating system from the target disk. Please read it carefully and click "Finish".


The seventh step, enter the main interface, click and click "Apply "Start copying MBR from one disk to another.

? Note:

? Due to copying The process involves the system disk, so it needs to be restarted.

? If your computer runs slowly on a traditional hard drive, you can use the "Migrate Operating System to SSD Wizard" to migrate the operating system to the SSD to optimize your computer performance.

? If you plan to copy the MBR system disk to the GPT disk, please make sure that your motherboard supports UEFI boot mode, because you need to change the BIOS boot mode to UEFI after the copy work is completed, and then you can successfully boot.

Finally, you must boot from the new hard drive. For laptops with a single disk tray, you can remove the old disk and put the new disk in its place, and your computer will boot from there. For desktop computers, you need to perform additional steps:

Step 1. Restart the computer and keep pressing a function key (such as F1, F2, ESC, Or Delete) to enter the BIOS setup menu.

Step 2. Find and navigate to the boot order option in the BIOS.

 Step 3. Change the boot order to put the new hard disk at the top of the list.

Step 4. Save the changes to the utility BIOS settings .

Step 5. Then your computer will successfully boot from the target disk.

This article shows how to copy MBR from disk to The other is in Windows 10 and tells you how to successfully boot the computer from the target disk. Hope you can get his help. In addition, if you want to perform similar operations on Windows Server 2019, 2016, 2012, 2008 or 2003, you can use AOMEI Partition Assistant Server.
