Fix: VirtualBox only showing 32-bit and no 64-bit versions

Is VirtualBox only showing 32-bit and no 64-bit versions of operating systems as options while creating a new virtual machine? Here's how to fix this problem.

Note: This may be obvious for most of you, but your host operating system should be 64-bit to run 64-bit guest operating systems in VirtualBox. Windows 10 still has 32-bit versions. Windows 11 has only 64-bit versions.

If VirtualBox doesn't show a 64-bit option on Windows 10 or 11, try the solutions on this page to fix the problem.

1. Make sure that 'Intel Virtualization Technology' and 'VT-d' are enabled

Enter your PC's BIOS settings and check if 'Intel Virtualization Technology' and 'VT-d' are enabled.

The following steps may be slightly different on your computer.

  1. Start or restart your PC.
  2. Press the keyboard key to enter the BIOS setup before Windows starts, so it's best to press the key a few times directly after you start your PC. The exact key or key combination to enter BIOS settings depends on your computer manufacturer and model. Common keyboard keys to enter the BIOS are F1, F2, F10, DEL (Delete), and ESC (Escape).
  3. Make sure Intel Virtualization Technology and VT-d are enabled.

  4. If you made changes, save the settings.

2. Windows 10 (host) must be a 64-bit operating system

This may be obvious for most of you, but your host operating system should be 64-bit to run 64-bit guest operating systems in VirtualBox. Windows 10 still has 32-bit versions. Windows 11 has only 64-bit versions.

  1. To check if your Windows 10 is a 64-bit operating system, right-click the Windows start menu button.
  2. Click on System.
    Open Windows 10 system information
  3. At System type located under Device specifications, you should see something like 64-bit operating system, x64-based processor.

  1. To check if Hyper-V is disabled, right-click the Windows start menu button.
  2. Click on Run.
    Open a Run command window in Windows 11
  3. Type optionalfeatures.exe in the 'Run' command window.
    Open Windows optional features
  4. Click on OK or press the Enter key on your keyboard.
  5. If the 'User Account Control' window appears, you click Yes. Depending on your settings, you may need to enter your administrator password first and then click Yes.
