How to Set Up a Virtual Machine Using VirtualBox

Virtual machines (VMs) allow you to run multiple operating systems on your computer without affecting your main setup. If you're new to virtualization, this guide will walk you through setting up your first VM using VirtualBox.

Step 1: Download and Install VirtualBox

• Visit the official VirtualBox website.
• Download the latest version for your operating system (Windows, macOS, or Linux).
• Run the installer and follow the setup instructions.

Step 2: Download an Operating System (ISO File)

To create a virtual machine, you need an operating system:

• For Linux, download from Ubuntu or Debian.
• For Windows, get an ISO from Microsoft.
• Ensure your system meets the VM's requirements.

Step 3: Create a New Virtual Machine

1. Open VirtualBox and click New.
2. Enter a name and select the operating system type.
3. Allocate RAM (at least 2GB for Linux, 4GB for Windows).
4. Create a virtual hard disk and select VDI (VirtualBox Disk Image).
5. Set the disk size (20GB recommended for Linux, 50GB for Windows).

Step 4: Configure the Virtual Machine

• Select your VM and click Settings.
• Go to System and adjust processor cores (2+ recommended).
• Under Display, increase video memory (128MB or more).
• In Storage, select the ISO file as a bootable disk.

Step 5: Install the Operating System

Now that your VM is set up, it's time to install the OS:

1. Click Start to boot your VM.
2. Follow the OS installation steps as if you were installing on a real PC.
3. Once installed, remove the ISO from the storage settings.

Step 6: Install VirtualBox Guest Additions (Optional)

To improve performance and enable features like clipboard sharing and screen resizing:

• Start your VM and log in.
• Click Devices > Insert Guest Additions CD.
• Run the installer inside the VM.
• Restart your VM after installation.

Conclusion

Congratulations! You have successfully set up your first virtual machine in VirtualBox. You can now explore different operating systems, test software, or use VMs for development. For more details, check out the VirtualBox User Manual.
