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 

To use Clonezilla, you need to download Clonezilla Live first, and burn it to CD, then boot the computer from the CD. At the first step, just click Enter.

Then, you can follow the guide to select language and the way your keyboard is laid out. Then, you can start to use Clonezilla to do a clone for your Windows operating system including Windows 7.

However, cloning with Clonezilla need a lot of steps which makes users confused and there are some limitations. For example, 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.

And all versions of Clonezilla live support machine with legacy BIOS. If your machine comes with UEFI secure boot enabled, you have to use an alternative to Clonezilla live. 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 brands. 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, thus 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.

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.

Summary

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 or advanced version to clone system in Windows 7.  For unlimited PCs, try AOMEI Backupper Technician.

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 are 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.
