With free virtualization tools like VirtualBox, you can have multiple virtual machines (VMs), complete with their own boot sequences and isolated storage. One of the most popular things to do with virtual machines is to run different operating systems on one computer without needing to reboot.
It’s pretty easy to create a VM on Windows to create a virtual environment to run Linux in. VMs are easy to manage, and when you’re done using them, you can delete them. You can even back up copies of the entire virtualized (guest) operating system if you need to.

If you’ve never used VirtualBox before, Virtualbox is a cinch to set up. Once you have it installed in Windows 10, you can set up a VM in a couple minutes with VirtualBox’s wizard. The VirtualBox manual’s step-by-step instructions are a great resource if you’re not quite sure where to start.
While using VirtualBox is a great way to try out one or more Linux distributions, there are some disadvantages. Virtualization comes with a performance hit due to overhead, though this is reduced if your CPU has virtualization support built-in. Intel calls its virtualization support VT-x, while AMD’s is called AMD-V. To take advantage of this technology, you also have to make sure that virtualization support is enabled on your motherboard (in the UEFI or BIOS) as well.
