It was showing 64-bit operating systems as one of those options in VirtualBox but you don’t know why there are only 32-bit versions listed below. There are two issues here. You either have Hyper-V turned on, or have Intel Virtualization Technology disabled in BIOS. Website:: https://www.facebook.com/TheProgrammingPortal/. I have downloaded and installed the newest virtualbox 4.3.20 for my Windows 7 (64-bit OS), but when I want to install 64-bit Linux, the New-Create Virtual Machine only displays 32-bit option, no 6. Go to the system configuration tab. You will find visualization technology as disabled. Turn it Enabled. Select virtualization technology row and press enter. Press F10 to save the changes and exit. Now I am able to select ubuntu 64 bit when I create VirtualBox. VirtualBox Showing Only 32-bit Guest Versions on 64-bit Windows 10 - 2019.

When trying to create a Virtualbox VM recently I was only presented with the option of creating a 32-bit client. After a bit of research it turns out this can be caused by incorrect settings in the BIOS or by a competing Virtual Machine software cohabiting the system.

CPU

Virtualbox Showing Only 32 Bit Windows 10

First of all your CPU must support the virtualization extensions. We can check this on a Bash console if you have installed the integrated feature.

If it returns a positive number, 1 or higher your CPU does support the virtualization extensions. You must still ensure it's enabled in the BIOS. If it returns 0 then your CPU does not support hardware virtualization.

BIOS

You must have hardware virutalization enabled in the BIOS to create and run 64-bit virtual machines.

The following BIOS features need to be enabled:

Showing
  • Intel Virtualization Technology [Enabled] (or AMD-v).

Hyper-V

If Hyper-V is enabled then Virtualbox will not be able to create 64-bit virtual machines.

If Hyper-V was enabled this will require a reboot.

Virtualbox 64 Bit Guest Not Listed

I know this looks like same issue that's been reported numerous times over the years, but I think this one is different.

Download Virtualbox 32 Bit


I've tried on 5 different 64-bit machines and made sure that on each of them both VT-x/VT-d are enabled and Hyper-V is not installed. Yet on three of the machines I am only allowed to select 32-bit guests and on the other two I can select 64-bit guests. What I've noticed is that the three machines that only offer 32-bit are running Windows 10 version 1709 and the two that offer 64-bit are running Windows 10 version 1703.
I know that Microsoft is pushing the 1709 updated so more and more machines will be running it over time. Can anyone else repro this issue? Any other workarounds I should try?
Thanks,
