Virtualbox does not have 64 bit

Question

Hi. I have a dell precision 5520. I need to install Ubuntu 16.04 (64-bit) via Virtualbox. However, Virtual box is not showing 64 bit version of any operating system, it is only showing 32 bit version of Ubuntu.

I enable all the virtualization-related settings in the BIOS and uninstall Hyper-V, and then uninstalled and reinstalled Virtualbox. After making those changes, problem still continues.

Would you please help me?

Thank you.

If you’be already enabled virtualization AND Vt-D in the BIOS, then this probably isn’t a hardware problem, so you might want to ask this on the Virtualbox forums. Or if you have access to Hyper-V, then consider using that instead. It’s faster because it’s the only Tier 1 hypervisor available for Windows (all others are Tier 2) and it supports Linux.

It doesn't really help to say that you've tried all solutions on the Internet. If everyone assumed that they should only offer suggestions if they have something they can't find anywhere else on the entire Internet, you probably wouldn't get any suggestions. Perhaps you can specify what you've actually tried?

To start off with the simple things, have you verified that all of the virtualization-related settings in the BIOS are enabled and that Hyper-V is NOT installed, and then uninstalled and reinstalled Virtualbox after making those changes?

If you are using Windows 10 and Windows Defender as your antivirus, disable "Core Isolation" in Windows Defender and restart.

Make sure Intel Virtualization Technology is enabled from BIOS.

Disable Microsoft Hyper-V from "Turn Windows Features On/Off".
