I am running VirtualBox v5.2.32 on an Ubuntu 18.04 host. I have created a Windows 10 (64-bit) guest. I installed VirtualBox v6.0.10 in the Windows 10 guest (Windows 10 Pro – v1903 – 64-bit). I am trying to create an Ubuntu (64-bit) guest inside the Windows 10 guest. I only see 32-bit options inside the Windows guest. After several attempts to resolve this, I am still only seeing 32-bit options.
Check If You Have an x64 CPU. The first thing you should do is to check if your computer has an x64 bit CPU. If you are using a 2 bit CPU, you will encounter the VirtualBox not showing 64 bit issue. Press Win + E keys to open the File Explorer, and then right-click This PC and select Properties. Hi, I use Windows 10 1511 64-bit. I installed the latest VirtualBox 5.0.10 r 104061. When I run VirtualBox, I see only 32-bit operating systems for choice available. In BIOS Intel Virtualization is enabled, Hyper-V in Windows 10 isn't installed. When running the installation of VirtualBox again, choosing Repair, afterwards I can see also 64-bit.
The purpose for creating a VM inside a VM is to be able to ensure that VirtualBox is working so that I can test Vagrant configuration inside a Windows 10 environment. Our Vagrant config is using 64-bit base images, so I need to be able set up 64-bit guests inside this Windows 10 guest.
…on the Ubuntu Host
I have checked Enable VT-x/AMD-V on the System > Acceleration tab in the Ubuntu host's VirtualBox config for the Windows 10 guest machine.
…on the Windows Guest
In the Windows guest machine, I can see that the host's physical CPU details are passed through in Settings > System > About and it shows as a '64-bit operating system, x64-based processor'.
This is a vanilla Windows 10 Pro installation, no additional software (i.e., no addon virus protection software).
I inspected Windows Features to ensure that the following are not checked:
- Guarded Host
- Hyper V
- Virtual Machine Platform
- windows Hypervisor Platform
- Windows Subsystem for Linux
…because my googleing seems to indicate that some or all of these might be an issue.
Based on a VirtualBox forum (I have a 64bit host, but can't install 64bit guests), using gpedit.msc, I set Local Computer Policy > Computer Configuration > Administrative Templates > System > Device Guard > Turn on Virtualization Based Security to Disabled. I also check that Windows Security > Device Security > Core Isolation Details is set to Off.
I have 'repaired' the VirtualBox installation. I have uninstalled VirtualBox, rebooted, reinstalled, and then rebooted again.
I looked at these related, previously asked questions and followed their suggestions as indicated in the steps above. Everything I am finding seems to be related to a Windows 64-bit host running directly on the host machine, not dealing with a Windows host which is itself a guest VM.
Hi All,After about a month of trying to fix this, with my own businesses IT support and weeks trawling through different internet threads for fixes to try, my last hope is you clever people to help me work out what an earth I am doing wrong!
I have a brand new Dell XPS 15 9560 with Windows 10 Enterprise 64bit installed.
It has a Intel i7-7700HQ CPU capable of virtualized technology.
In the BIOS, Virtualisation and VT-D are both enabled as well as HT Technology, not that that should matter.
In Windows Features, Hyper-V is completely removed.
Virtualbox Extension Pack Download Windows 10
Yet, no matter what I do, I absolutely cannot get a latest install of Oracle Virtualbox 5.1.28 to show anything but Windows 32 bit clients, rendering it useless to me.My platforms for testing our software ect are all Windows 7 64 bit VM's on my older lenovo laptop running Windows 7 64bit and I have never had this problem, not once!
Other things to note, we use Bitlocker, not sure that would cause a problem, doubt it.
Please take pity on me and tell me what an earth I am doing wrong, I could really do with getting this working!
