A system image is a backup that contains everything stored on your computer, including the full installation of Windows 10, settings, applications, and all your files, as well as any additional drives you may have connected. If your computer fails, you can use the system image backup to restore your computer, getting you up and running in a matter of minutes on the same or different hard drive.
To create a full backup using Windows 10's system image tool, you need to connect external storage with enough available space and then use these steps.
- Open Control Panel.
- Click on System and Security.
Click on Backup and Restore (Windows 7).
On the left pane, click the Create a system image link.
- Under "Where do you want to save the backup?" select the On a hard disk option.
Using the "On a hard disk" drop-down menu, select the storage to save the backup.
- Click the Start backup button.
Once you completed these steps, the wizard will proceed to create a full backup of your system, including everything that is stored on the main drive, as well as the system reserved partition.
