How to Install Kali Linux in VirtualBox

Kali Linux is a powerful tool for cybersecurity experts and beginners. It helps you test computer safety, learn hacking (ethically!), and protect systems. But installing it directly on your computer can be risky. That’s why using VirtualBox is safer. VirtualBox lets you run Kali Linux like an app without harming your main computer. Ready to learn how to install Kali Linux in VirtualBox? Let’s go!

Step 1: Download VirtualBox

First, download VirtualBox. It’s free and works on Windows, Mac, and Linux. Go to the official VirtualBox website and click “Download.” Pick your computer’s operating system (like Windows or macOS). Wait for the file to download, then open it. Follow the simple steps to install VirtualBox. It’s like installing any other app!

Tip: Restart your computer after installing VirtualBox to avoid errors.

Step 2: Get the Kali Linux ISO File

Next, download the Kali Linux ISO file. This is the “disc image” you’ll use to install Kali Linux. Visit the official Kali Linux downloads page. Choose the “Installer Images” option. Pick the “64-bit” version unless your computer is very old. Click “Download” and wait. The file is big (about 3-4 GB), so grab a snack!

Note: Kali Linux is free, but avoid unofficial websites. Only trust kali.org.

Step 3: Create a New Virtual Machine

Open VirtualBox and click “New.” Name it “Kali Linux” and select “Linux” as the type. For “Version,” choose “Debian (64-bit).” Click “Next.” Now, set the memory (RAM). Use at least 4 GB (4096 MB) if your computer has 8 GB or more. If not, use 2 GB.

Click “Create a virtual hard disk now” and select “VDI.” Choose “Dynamically allocated” to save space. Set the hard disk size to 20-25 GB. Kali Linux needs space for tools and updates. Click “Create.”

Step 4: Set Up Kali Linux in VirtualBox

Your new Kali Linux machine is ready! Click “Start” (the green arrow). A pop-up will ask for a “start-up disk.” Click the folder icon, find your Kali Linux ISO file, and select it. Press “Start.”

The Kali Linux setup screen will load. Choose “Graphical Install” and follow these steps:

1. Pick your language and location.
2. Leave the hostname as “kali” (or type a fun name!).
3. Skip the domain name (just press Enter).
4. Set a password (remember it!).

Step 5: Install Kali Linux

Next, partition the disk. Choose “Guided – use entire disk.” Select the virtual hard disk you created (it should be the only option). Pick “All files in one partition” and finish. Confirm changes by selecting “Yes” and wait. The installer will copy files. This takes 10-20 minutes.

After installing, click “Continue” to reboot. VirtualBox might show an error—ignore it! Go to the top menu, click “Devices > Optical Drives > Remove disk.” Now restart the VM.

Step 6: Log In and Update Kali Linux

Type “kali” as the username and your password. Welcome to Kali Linux! First, update the system. Open the terminal (black square icon) and type:

sudo apt update && sudo apt upgrade -y

This downloads the latest tools and fixes. Wait till it finishes.

Pro Tip: Use “sudo” before commands to run them as admin.

Step 7: Install VirtualBox Guest Additions

Guest Additions make Kali Linux run smoother. Click VirtualBox’s top menu: “Devices > Insert Guest Additions CD image.” Open the terminal and type:

sudo apt install -y build-essential dkms linux-headers-$(uname -r)

Then, go to the CD icon on the desktop, right-click, and open the terminal. Type:

sudo ./VBoxLinuxAdditions.run  

Reboot Kali Linux. Now, it’ll work better with your mouse and screen!

Why Use Kali Linux in VirtualBox?

VirtualBox keeps your main computer safe. If you make a mistake in Kali Linux, your real files stay untouched. It’s also free and easy to delete. Plus, you can test hacking tools without breaking laws. Always use Kali Linux responsibly!
