Install Virtual box on your PC
Create your first new VM (The specification is below)
Download and Install Linux CentOS on your virtual box (PLEASE NOTE: During installation you will get the option to turn Ethernet ON or OFF. Please keep the Ethernet ON for your installation)
I would highly recommend that you install Linux OS the first time and then delete it. Then install the 2nd time and keep it. This will be a good practice for the OS installation
After the installation familiarize yourself with GNOME desktop environment. Most likely you will not be working a lot on the GUI but I would still recommend to know a few features of desktop GUI
Specification for Linux VM is as follow:
Memory = 4G
Disk Space = 10 or 20G
CPU = 1
