A dual boot hard drive means you installed two operating systems on the same hard disk, and the latter one does not overwrite the former. And you can choose to boot from either of them at the startup of dual system.

Speaking of this topic, you may have many questions, for example, is it possible to clone a dual-boot system?  Will non-Windows system be cloned? What is the best way to clone a dual booting Windows? That's what this article will talk about and let's have a glance about it.

Situations to Clone Dual Boot Hard Drive

First of all, I want to tell you responsibly that cloning dual-boot system is feasible. Cloning hard drive with dual boot system is very similar to clone a single booting operating system drive. Then, see below and learn the common 3 situations. 

1. Clone disk to a larger disk for big capacity. Usually, desktop computer has more than one drive bays holding drive while most laptop only has one. 

2. Replace HDD with SSD for better performance. In general, your computer will be equipped with a traditional hard drive, but it's not good enought for you to smoothly play large games or perform multiple tasks. 

3. Avoid reinstalling the operating system and programs. Your will be suggested to reinstall Windows when your disk/system goes wrong owing to hardware failure, system crash, virus, file system failure, etc. But it's time-consuming and error-prone, not suibale for most users.

Will Non-Windows System Be Cloned?

In windows-based operating system, disk cloning software like AOMEI Backupper Professional will clone the entire dual-boot system effortlessly including the operating system, system reserved partition/EFI partition or other boot files, installed programs and saved personal files etc. But if you have non-Windows system on the existing computer, such as Linux, this software will not work and you could consider using Clonezilla or other software. 

It's suggested to use "Disk Clone" feature which will clone everything on the disk including both operating system. But if you use "System Clone" feature, it only clone the current running operating system. Therefore you need to clone twice and it's best to clone previous version between two system.  And this does not guarantee success.

Dual-boot Disk Cloning Software for Windows 

As you may know, this article will show you how to transfer dual boot to SSD or a new hard drive with AOMEI Backupper Professional, one of the best way. Then, let's have a closer look at this software. 

AOMEI Backupper Professional is a trust and reliable disk cloning software used worldwide and support cloning hard drive including dual-boot and dynamic disk in Windows 7/8/8.1/10/XP/Vista. Also, system clone and partition clone are supported. The cloning process is the same as cloning hard drive in a single operating system.

In addition, it has some useful features you may need.

  • Clone disk to larger disk without left unallocated space. The disk cloning software will make an exact copy of original disk, the cloned disk is exactly the same as original disk and the extra space becomes unallocated and invisible. So, you need to adjust partition size of destination disk with "Edit Partitions" during the cloning process.

  • Clone large HDD to smaller SSD with intelligent clone feature. With the help of intelligent clone, this software only clone used sectors, so you just need to ensure the used space on old disk is smaller than or equal to new disk.

  • Clone MBR disk to GPT disk without converting partition style, and vice versa. In general, cloning disk with different partition style need to convert target disk first, but this software can do this for you during cloning process.

  • Improve SSDs' performance with "SSD Alignment". In a simple word, this feature makes your SSD have a faster reading & writting speed, and can extend life span of SSDs.

  • Clone all sectors or not with "Sector by sector clone". This feature allows you to clone all sectors including unused.
