Learn how to make an ISO image backup of your PC’s hard drive. When disaster strikes you can restore the computer from the image. I encourage you to visit MakeUseOf (see source link below) to learn about the options available on imaging a disk in Windows 7, 8.1 and 10.
Thanks to the ISO image format, it is possible to back up your entire PC. This essentially creates an exact copy of your entire drive or selected directories. You’ll be able to restore the image backup should disaster strike.
