Why Can't I Choose the 64-Bit Version in VirtualBox?

Are you trying to set up a virtual machine in VirtualBox, but it's only giving you the option of 32-bit operating systems? You're not alone! This is a common issue that many users face when using VirtualBox with Windows 10. In this article, we'll explore the reasons behind this limitation and provide a simple solution to get around it.

Step-by-Step Solution

To fix this problem, you need to follow these steps:

1. Press the right keyboard key to enter the BIOS setup: The exact process may vary depending on your computer, so make sure to check your manufacturer's instructions.

2. Check if “Intel Virtualization Technology” and “VT-d” are enabled: Navigate to your BIOS settings and verify that both of these features are turned on.

Important Note

Make sure your host operating system (Windows 10) is running a 64-bit version. If you're using a 32-bit version, you won't be able to run 64-bit guest operating systems in VirtualBox.

What's Causing the Problem?

The reason behind this limitation is that Windows 10's Hyper-V feature conflicts with VirtualBox's virtualization capabilities. To fix this issue, you need to disable Hyper-V and enable Intel Virtualization Technology (VT) in your BIOS settings.

Disable “Memory integrity” in Windows 10

To do this, follow these steps:

1. Press the Start button and type 'Windows Defender Firewall' in the search bar.

2. Click on 'Windows Defender Firewall' to open it.

3. Click on 'Turn Windows features on or off.'

4. Uncheck the box next to 'Memory integrity.'

Make Sure That “Intel Virtualization Technology” and “VT-d” Are Enabled

In your BIOS settings, verify that both 'Intel Virtualization Technology' and 'VT-d' are enabled.

By following these simple steps, you should be able to choose the 64-bit version of an operating system in VirtualBox. If you're still having trouble, try disabling Hyper-V again or checking for any other potential issues with your system configuration.

In this article, we've explored why VirtualBox is only showing 32-bit versions of operating systems as options and provided a step-by-step solution to fix the problem. By disabling 'Memory integrity' in Windows 10, checking if your host operating system is running a 64-bit version, and ensuring that 'Intel Virtualization Technology' and 'VT-d' are enabled in your BIOS settings, you should be able to choose the 64-bit version of an operating system in VirtualBox.
