This issue can be resolved by following a series of troubleshooting steps. In this guide, we’ll guide you through the process of identifying and fixing the problem.
Understanding the Issue
The “Kernel driver not installed” error typically occurs when the VirtualBox kernel module fails to load or is not installed correctly. This can happen due to various reasons, such as outdated packages, missing dependencies, or conflicts with other kernel modules.

Check for any error messages. If successful, restart VirtualBox and see if the issue persists.
