VirtualBox will allow you to create a virtual computer on which you can install another operating system. Such a machine consists of the virtual components of a real PC or laptop. This refers to the hard drive, video editor, "RAM" and other components, without which it is impossible to imagine the computer. At the same time, the OS installation process will not differ in any way from the installation on a real PC. You can download the VirtualBox program in those cases when you need to study the operation of a new OS, software, etc.
