How to make a backup of your entire computer for Windows 10/11?

Clonezilla is a free and open-source software that allows you to create complete backups (clones) of your entire computer or specific disks and partitions. It's widely used for system backups, recovery, and disk imaging. Here's how you can use Clonezilla to make a backup of your entire computer:

1. Download Clonezilla: Visit clonezilla and download the ISO file for creating a bootable USB or CD/DVD.

2. Create Bootable Media: Use tools or burn the ISO to a CD/DVD to create bootable media.
