What is Clonezilla?

Clonezilla is a free and open source software for disk imaging and cloning. It absorbed the merits of both Norton Ghost and Partition Image. It supports not only cloning the whole system, but also doing bare metal backup/recovery. It is very flexible for users.

Clonezilla supports many file systems including ext2/ext3/reiserfs/xfs/jfs; Meanwhile, it supports FAT/NTFS on Windows system, which means you can use Clonezilla to clone not only GNU/Linux, but Windows operating system including Windows 10/8/7. Besides, Clonezilla can make a Multicast clone with PXEBoot, which is of great help for cloning a large number of systems.

Clonezilla has two versions - Clonezilla Live and Clonezilla SE. Clonezilla Live is designed to run on machines without installation. It can be operated through the LiveDistro on a medium like CD/DVD/USB, or the unicast service. Clonezilla SE uses the multicast to clone multiple disks. Clonezilla clones fast because it only clones the used part. It keeps the same size of a disk or partition, so you can use it to create a real clone.

How to use Clonezilla in Windows 7 for system clone 

Before you start, do the following preparations:

  • Download Clonezilla Live and burn it to CD.
  • Connect a target drive that is large enough to hold all cloned data.

Then, follow the instructions below:

1. Boot your computer from the CD. For the first step, just click Enter.


2. Then, select language and the way your keyboard is laid out.

3. When the start screen displays, select "Start Clonezilla" and press Enter. Then, you can start to use Clonezilla to do a clone for your Windows operating system including Windows 7.

Although you can follow the wizard to finish the clone job, there are more than ten steps involved, which makes average users confused. And there are some limitations.

  • The destination partition must be equal to or larger than the source one. In other words, you cannot clone larger drive to smaller drive via Clonezilla.
  • All versions of Clonezilla live only support machines with legacy BIOS. If your machine comes with UEFI secure boot enabled, you have to use an alternative to Clonezilla live.
  • The disk/partition to be imaged/cloned has to be unmounted...

Fortunately, there is other software that can replace Clonezilla.

Flexible way to clone system in Windows 7

AOMEI Backupper Professional is a great powerful software that provides you with two ways to clone for Windows 7 and other Windows PC OS: Disk Clone or System Clone. 

Both of them clone HDDs/SSDs or MBR and GPT disks, regardless of disk brand. And it clones only used sectors by default, thus you can easily clone system to larger or smaller drive. Then, which one should you choose?

Disk Clone: It will clone the entire disk including the operating system, programs, files, system settings, etc.
System Clone: It will clone only system partition and boot-related partition(s), which requires less disk space and cloning time.

Thus, you can choose one of them, depending on the disk space of destination disk. If it's big enough, it's suggested to clone entire disk so that you don't need to worry about data loss in other partitions. If not, clone OS only with System Clone feature. 

Please download this software to have a try! It applies to Windows 7/8/10/11/XP/Vista. For server users, try AOMEI Backupper Server.

Step 2. By default, system drive and boot related partitions are selected. Here you need to select a destination path to put in your clone files. Select it and click Next.

Step 3. Here you will move to the Operation Summary, where you can confirm the information of your operation. If there is no problem, click Start Clone to launch the progress.

You can benefit from the following features if you enable it:

  • Sector by sector clone: it will clone every byte of the source partition, which takes a lot of time and occupy more space on your destination space. It's particularly useful while cloning a system disk, you don't need to worry about system reserved partition missing issue after cloning. 

  • SSD Alignment: the function can optimize the performance of SSD, to be specific, so, if your destination space is an SSD, here we highly recommend you check it.  

Afterward, you just need to wait for the process completes. Replace the old drive with the new one, or change boot order in BIOS to boot from the new disk.

Change Boot Order


You can use Clonezilla in Windows 7 for system cloning, but it's complicated and restricted. Thus, it's suggested to use AOMEI Backupper Professional to clone system in Windows 7.

With it, you can clone all brands of HDDs and SSDs, whether it's MBR or GPT. And cloning system from larger drive to smaller drive is supported. If you are cloning HDD to SSD, you can further improve the reading and writing speed of SSD disk. 

Actually, AOMEI Backupper still has many other functions that Clonezilla cannot reach, such as create system backup image for Windows 7, synchronize files between two computers, etc.
