1. Download and Install VirtualBox: If you haven't already, head over to the official VirtualBox website and download the version compatible with your host operating system (Windows, macOS, or Linux). Install it like any other software.

2. Download Kali Linux ISO: Go to the official Kali Linux website and download the latest ISO file. Choose the appropriate version (64-bit or 32-bit) for your system. Make sure to download from the official source to ensure you get a safe and verified file.

3. Create a New Virtual Machine in VirtualBox:

   • Open VirtualBox and click on "New".
   • Name your virtual machine (e.g., "Kali Linux"), choose "Linux" as the type, and "Debian (64-bit)" or "Debian (32-bit)" as the version, depending on the Kali Linux ISO you downloaded. Be sure to select the correct version based on your ISO. If your system is 64-bit and you downloaded a 32-bit ISO, the installation might fail.
   • Allocate RAM: Allocate a sufficient amount of RAM. A minimum of 2GB is recommended, but 4GB or more is ideal for better performance. Keep in mind that allocating too much RAM can impact the performance of your host machine.
   • Create a Virtual Hard Disk: Choose to create a virtual hard disk. Dynamically allocated storage is usually a good choice, as it will only use the space it needs initially, and grow as needed. You can choose a fixed size if you want to. In general, it’s recommended to start with at least 20GB and consider more depending on your expected usage.
   • Choose the location and size of the virtual hard disk.

4. Configure Virtual Machine Settings:

   • Select your newly created virtual machine in VirtualBox, and click "Settings".
   • In the "System" tab, increase the base memory (RAM) if needed (as mentioned above, 2GB or more is recommended).
   • In the "Processor" tab, assign at least two processor cores for better performance. Allocate based on how many cores your host machine has available.
   • Go to "Storage". Click on the empty disc icon under "Controller: IDE" or "SATA". Then, click on the disc icon next to "Optical Drive" and select "Choose a disk file". Browse to the Kali Linux ISO file you downloaded. This will mount the ISO file as a virtual CD-ROM.
   • In the "Network" tab, you can configure your network settings. The default "NAT" setting is usually fine, but if you need your virtual machine to be on the same network as your host machine, you can change it to "Bridged Adapter".

5. Start the Virtual Machine and Install Kali Linux:

   • Click "Start" to boot up the virtual machine.
   • Select "Graphical install" to begin the installation process. If you are comfortable with the command line, you can choose the text mode installation. However, graphical install makes the installation easier for beginners.
   • Follow the on-screen prompts. Choose your language, location, and keyboard layout.
   • Configure the hostname and domain name. You can usually leave the domain name blank.
   • Set up your user account by creating a username and password. Make sure to choose a strong password and remember it, because you'll need it every time you log in.
   • Partition the disk: Choose the guided partitioning method, usually "Guided - Use entire disk". This option is the easiest for beginners, and it’ll format and partition your virtual hard drive. Then, select the disk to be partitioned. Finally, choose "All files in one partition" and confirm the changes. If you are an advanced user, you can choose custom partitioning methods.
   • Wait for the installation to complete. The system will copy the necessary files and configure the operating system. This process may take several minutes.
   • When prompted, install the GRUB boot loader on the hard drive. This step allows your Kali Linux installation to boot up correctly every time.
   • Once the installation is complete, click "Continue" to restart the virtual machine.
   • At the login screen, enter the username and password you created. And voila! You've successfully installed Kali Linux in VirtualBox.

6. Install VirtualBox Guest Additions (Highly Recommended):

   • After logging in, go to the "Devices" menu in VirtualBox and select "Insert Guest Additions CD Image…". This will mount the Guest Additions CD image in your virtual machine.
   • Open a terminal in Kali Linux and run the following command to navigate to the CD-ROM: cd /media/cdrom0 or cd /media/cdrom
   • Run the Guest Additions installer: sudo ./VBoxLinuxAdditions.run This will install the necessary drivers and utilities.
   • Restart your Kali Linux virtual machine. After the restart, you should be able to resize the window, share the clipboard, and enjoy better performance. This will improve the integration between your host and virtual machine, such as enabling shared clipboards and drag-and-drop functionality, and enhancing the video performance. If the installation fails, try updating your system before running the installation again. Open a terminal and run sudo apt update && sudo apt upgrade. Then try installing the Guest Additions again.
