6 Methods to Fix VirtualBox Result code: E_FAIL (0x80004005) Windows Error

VirtualBox When it cannot open a virtual machine, the error code “E_FAIL (0x80004005)” is displayed. This error can be caused by problems in the VirtualBox app or configuration files.

This article explains the possible causes of and solutions to the E_FAIL (0x80004005) VirtualBox error in Windows.

2. Start the Windows Hypervisor, (HyperV),

Hyper-V Windows features that allow you to use multiple operating systems in virtual machines. Hyper-V might be experiencing an error that makes it impossible to connect to virtual machines within VirtualBox.

You can restart Hyper-V under Windows (see the steps below), to fix problems that prevent VirtualBox sessions from being run.

bcdedit /set hypervisorlaunchtype auto

When Command Prompt shows a message indicating that the operation was successful, restart your computer. Start VirtualBox, and open the virtual machine.

3. Savings State should be discarded

VirtualBox might also show the E_FAIL (0x80004005) Error if it detects an error with the system Virtual session saved as a state . . If you are unable to restore a session of the virtual machine, then discard any saved states and restart it.

You can use the below troubleshooting tips to determine if the “Discard Saving State” option is grayed out. This means the virtual machine doesn’t have any saved states.

4. VirtualBox Configuration Files – Rename

Force-quitting VirtualBox A virtual machine that is not closed can cause an E_FAIL (0x80004005) error. Let us explain why and how this occurs.

Assume you are using VirtualBox to create a virtual “Linux PC.” VirtualBox changes the file name of your virtual machine from “Linux PC.vbox” to “Linux PC.vbox–prev” and creates a temporary copy for the current session.

VirtualBox changes the name of the temporary file to Linux.vbox.vbox after you quit the virtual machine session. VirtualBox creates a “Linux PC.vbox.prev” file as a backup. VirtualBox then overwrites it every time you begin a new session.

The file conversion process can be disrupted if VirtualBox is closed after you close it. This will prompt you to get the “Result code: E_FAIL (0x80004005) error when you attempt to launch VirtualBox again.

In the VirtualBox folder of your PC, open it and see if there is a .vbox You can file to your virtual machine. You can only use temporary files (.vbox-tmpBackup (.vbox-prevIf you find () files in the directory, it is likely that VirtualBox was forced to close while using a virtual machine.

The backup file can be renamed to fix the problem. This will allow your virtual machine to start up again. To fix the problem, close VirtualBox Manager and then follow these steps.

1. In File Explorer, open the VirtualBox’s file manger. Open your local disk (C:Double-click on the folder ‘( Users Folder, then select the computer or account you wish to use.

2. Open the VirtualBox VMs folder, select Machines, Double-click on the folder of your virtual machine.

3. Save both files (.vbox.tmp &.vbox.prev), and copy them to another location on your computer. The temporary file’s extension can be changed from .vbox-prev to .vbox.

4. Select OK Follow the prompts to open VirtualBox and close the message.

5. Change the VirtualBox settings and close VirtualBox .vbox Send it back .vbox-prev If the error continues, you can rename it. If the error persists, you can rename it .vbox-temp Send an email .vbox You can now check whether VirtualBox runs this virtual machine.

Note: Virtual machine configuration files are stored in older VirtualBox versions (v3.2 or earlier) .xml format—not .vbox. .xml-prev or .xml-tmp Use this format .xml.

5. Allow Virtualization to be enabled in BIOS Settings

Virtual machines can only be run if your CPU or hardware virtualization is enabled. VirtualBox will indicate that hardware virtualization has been disabled if VirtualBox contains “AMD-v”, or “VTX” keywords within the error details.
