Back2Skills Official Step-by-Step Guide for Beginners

🎯 Why Install Kali Linux?

Kali Linux 2025 is the official operating system for ethical hackers, penetration testers, and cybersecurity learners.
It comes pre-loaded with tools like Nmap, Burp Suite, Metasploit, and Wireshark — ideal for CEH v13 preparation and other cybersecurity certifications.

Installing Kali in a virtual machine (VM) lets you:

  • ⚙️ Practice safely without modifying your main system.
  • 💻 Run both Windows/macOS and Kali simultaneously.
  • 🔐 Create snapshots to test tools without risk.

🧩 What You’ll Need

Before starting, prepare these essentials:

⚡ System ResourcesAt least 8 GB RAM, 20–30 GB disk space, and Intel VT-x/AMD-V enabled
🌐 Internet ConnectionFor updates and additional package downloads

🪟 Installing Kali Linux 2025 on Windows (Virtual Machine)

Step 1: Install VirtualBox

  1. Go to virtualbox.org.
  2. Download and install VirtualBox for Windows.
  3. Also install the VirtualBox Extension Pack for better USB and display support.

Step 2: Download Kali Linux 2025 ISO

  • Visit the official Kali Linux download page → choose the 64-bit Installer ISO.
  • Verify the checksum (optional but recommended for integrity).

Step 3: Create a New Virtual Machine

  1. Open VirtualBox → New.
  2. Name it “Kali Linux 2025.”
  3. Choose Type: Linux and Version: Debian (64-bit).
  4. Allocate 4096–8192 MB RAM (4–8 GB).
  5. Create a Virtual Hard Disk → VDI → Dynamically Allocated → 30 GB.

Step 4: Mount the ISO File

  1. Select your Kali VM → Settings → Storage.
  2. Under “Controller: IDE,” click the empty disk icon → choose Kali Linux 2025 ISO file.

Step 5: Start the Virtual Machine

  • Click Start to boot into the Kali installer.
  • Choose Graphical Install.
  • Follow the wizard:
    • Language → English
    • Location → Your region
    • Keyboard → U.S.
    • Username & Password → create secure credentials
    • Partition → Guided (use entire virtual disk)
    • Install GRUB bootloader

🧠 Tip: If asked, install GRUB on /dev/sda to make Kali bootable inside the VM.

Step 6: First Boot and Updates

Once installation completes:

  1. Login using your credentials.
  2. Open a terminal and run: sudo apt update && sudo apt upgrade -y
  3. (Optional) Install VirtualBox Guest Additions for better display and shared clipboard:
    • Devices → Insert Guest Additions CD image.
    • Run the installer inside Kali.

✅ You now have a fully functional Kali Linux 2025 environment on Windows.

🍏 Installing Kali Linux 2025 on Mac (Virtual Machine)

Step 1: Install Virtualization Software

Choose your software:

  • Intel Mac → VirtualBox or VMware Fusion (Pro/Free Personal Use).
  • Apple Silicon (M1/M2/M3) → VMware Fusion for Apple Silicon or UTM (Virtualization for ARM64).

Download from:

Step 2: Download the Correct ISO

  • Intel Mac → x64 Installer ISO.
  • Apple Silicon → ARM64 Installer ISO.
    Get it from kali.org/get-kali.

Step 3: Create the Virtual Machine

  1. Open VirtualBox or VMware Fusion.
  2. Click New → Linux → Debian (64-bit).
  3. Allocate 4–8 GB RAM and 30 GB storage.
  4. Attach the downloaded ISO file as the boot image.

Step 4: Install Kali Inside the VM

  1. Boot the VM → choose Graphical Install.
  2. Follow the setup prompts:
    • Language → English
    • Region → India/USA (depending on preference)
    • Timezone & user credentials
  3. Complete installation and reboot into Kali.

Step 5: Optimize for Performance

Inside Kali, run:

sudo apt update && sudo apt upgrade -y
sudo apt install open-vm-tools -y

Then reboot to activate full-screen and clipboard support.

✅ Your Kali Linux 2025 VM is now ready on macOS.

🔐 Best Practices for Beginners

  • Use snapshots in VirtualBox/VMware before testing new tools.
  • Never run penetration-testing tools on unauthorized targets.
  • Keep Kali updated weekly.
  • Backup your virtual machine folder regularly.
  • Create a shared folder between host OS and Kali for reports, scripts, and screenshots.

🧭 Key Takeaways

  • The virtual machine method is the safest and easiest way for beginners.
  • Works seamlessly on both Windows and Mac.
  • Avoids partitioning, data loss, or hardware conflicts.
  • Essential first step for CEH v13, penetration testing, and Back2Skills cybersecurity courses.
