Setting up Kali Linux as your main operating system means installing Kali directly on your computer instead of running it inside a virtual machine. In the context of a Metasploit certification or ethical hacking training, this gives you a full-time security testing environment with direct access to system resources, tools, and hardware. It can offer better performance than a virtual machine, especially when running multiple tools, handling packet capture, or using external devices such as wireless adapters.
In this topic, you learn the basics of preparing your system for installation, such as backing up important files, choosing the correct Kali Linux image, and creating a bootable USB drive. You also learn the difference between using Kali as a main OS and using it in a virtual machine, so you can understand the advantages and trade-offs. Installing Kali as the main OS usually involves disk partitioning, selecting installation options, creating a user account, and completing the setup process carefully.
After installation, the focus is on first-time configuration: updating packages, installing essential tools if needed, checking drivers, and confirming internet and network settings are working properly. You may also review safety and usage practices, since Kali is a specialised security distribution and should be used responsibly in authorised lab environments.
By the end of this topic, you should understand what it takes to run Kali Linux as your main OS and how to prepare it for safe Metasploit practice.
