Many of us install multiple (more than one) Windows operating systems on a single computer. It is useful and effective as you don’t have to purchase a separate computer for each operating system. You can install multiple OS in a single machine, and according to your requirement, you can boot in the selected OS.
Suppose you have installed Windows 8.1 and Windows 10 on a single PC; you can configure the boot to launch the default OS, either Windows 8.1 or Windows 10. This means either you can set Windows 10 as a default OS or Windows 8.1 as a default OS. When you boot your computer, it will automatically start on the default OS. Suppose you have set Windows 10 as the default OS; every time you start your machine, Windows 10 will be loaded by default because it comes first on the boot menu. If you have to start your PC in Windows 8.1, on startup, change the boot to Windows 8.1, Windows 8.1 will load automatically.
