Troubleshooting VirtualBox Result Code E_FAIL 0x80004005 Error in Windows

VirtualBox is a powerful tool for running virtual machines on your computer, allowing you to experiment with different operating systems and software configurations without affecting your main system. However, like any software, it's not immune to errors. One common issue that Windows users encounter is the "Result Code: E_FAIL (0x80004005)" error. This error can be frustrating, but fortunately, there are several steps you can take to troubleshoot and resolve it.

Update VirtualBox

The first step in troubleshooting any software issue is to ensure that you're using the latest version. VirtualBox developers regularly release updates that address bugs and compatibility issues. Visit the VirtualBox website and download the latest version for your operating system. After updating, try running VirtualBox again to see if the error persists.

Check System Requirements

VirtualBox has certain system requirements that must be met for it to run smoothly. Ensure that your computer meets the minimum requirements specified by VirtualBox. Pay particular attention to factors such as available RAM, CPU resources, and disk space. If your system falls short of the requirements, consider upgrading or optimizing its performance.

Disable Hyper-V

If you're running Windows 10 Pro, Enterprise, or Education editions, Hyper-V may be enabled by default. Hyper-V is Microsoft's virtualization solution and can conflict with VirtualBox. To disable Hyper-V, open the Control Panel, navigate to "Programs" > "Turn Windows features on or off," and uncheck the "Hyper-V" option. Restart your computer after making this change and then try running VirtualBox again.

Reinstall VirtualBox

Sometimes, the installation files of VirtualBox can become corrupted, leading to errors like E_FAIL. To rule out this possibility, try reinstalling VirtualBox. First, uninstall the existing installation through the Control Panel or using a third-party uninstaller tool. Afterward, download the latest version of VirtualBox from the official website and install it fresh.

Run VirtualBox as Administrator

Running VirtualBox with administrative privileges can sometimes resolve permissions-related issues that lead to E_FAIL errors. Right-click on the VirtualBox shortcut or executable file and select "Run as administrator." If prompted, confirm the action. Test whether running VirtualBox as an administrator resolves the error.

Check Antivirus/Firewall Settings

Antivirus or firewall software on your computer can sometimes interfere with VirtualBox's operation. Temporarily disable your antivirus or firewall software and see if the error persists. If the error goes away after disabling the security software, you may need to add VirtualBox to its list of allowed applications or create an exception.

Verify Virtualization Support in BIOS

Virtualization support must be enabled in your computer's BIOS for VirtualBox to function properly. Restart your computer and enter the BIOS settings (usually by pressing a key like F2 or Del during startup). Look for an option related to virtualization (often called VT-x for Intel processors or AMD-V for AMD processors) and ensure that it is enabled. Save your changes and exit the BIOS, then try running VirtualBox again.


The E_FAIL (0x80004005) error in VirtualBox on Windows can be caused by various factors, including outdated software, conflicting virtualization technologies, or system misconfigurations. By following the troubleshooting steps outlined above, you should be able to identify and resolve the underlying issue. If the error persists despite your efforts, consider seeking assistance from VirtualBox forums or contacting their support team for further guidance. With patience and persistence, you can get VirtualBox up and running smoothly on your Windows system, allowing you to continue enjoying the benefits of virtualization.
