mhbell Posted July 3, 2017 Share Posted July 3, 2017 I downloaded and installed the latest version of Virtual Box in Windows 10 as host. Tried to run a 64 bit Linux Distro as guest, it would not work. In VB all of the listed distro's and Windows are 32 bit. What gives My windows 10 and all of my Linux Distros are 64 Bit and so is my CPU. This only happens when using Windows as the host using Virtual Box. It works fine in Linux.

Peachy Posted July 4, 2017 Share Posted July 4, 2017 I've noticed this behaviour if I have Hyper-V installed. For some reason, installing Hyper-V in Windows 10 and 8/8.1 causes VirtualBox and VMware Workstation to not be able to create 64-bit VMs. 32-bit ones yes.

Is there a fix for this problem and if so what do I need to do.Mel Quote Link to comment Share on other sites More sharing options...
Peachy Posted July 4, 2017 Share Posted July 4, 2017 First, do you actually have Hyper-V installed? If you didn't install it explicitly it will be installed if you also install the native Docker Windows client. If none of these are relevant to your situation, double-check your BIOS/UEFI settings and make sure Intel VT-x (virtualization settings) is enabled. Another fix is to re-install VirtualBox (don't uninstall it first) and choose the Repair option. Quote Link to comment Share on other sites More sharing options...
raymac46 Posted July 4, 2017 Share Posted July 4, 2017 (edited) Here is a good reference on this problem. I had it on my AMD based laptop and enabling virtualization in the BIOS fixed it for me. https://forums.virtu...php?f=1&t=62339 Edited July 4, 2017 by raymac46 Quote Link to comment Share on other sites More sharing options...
goretsky Posted July 5, 2017 Share Posted July 5, 2017 Hello, Here's how to disable Hyper-V in Windows 10, step-by-step: Open the Program and Features applet (filename APPWIZ.CPL) from the Control Panel. In the left navigation pane, select Turn Windows features on or off. Select the Hyper-V tree control and expand it. Beneath it you will see two options, Hyper-V Management Tools and Hyper-V Platform. Uncheck (de-select) the Hyper-V Platform option. Click on OK when done to uninstall Hyper-V. A reboot may be required when done to finish uninstalling Hyper-V.

mhbell Posted July 5, 2017 Author Share Posted July 5, 2017 (edited) There is no Hyper-v in the Bios or in Windows and I can find no VT-x to enable. It must be enabled because Virtual Box works fine in Linux. my processor is a AMD 64 bit A-8 7600 radeon. Here is more info. Under (services) there are several Microsoft Virtual Settings. No Hyper-v or tree. Mel Edited July 5, 2017 by mhbell Quote Link to comment Share on other sites More sharing options...

I have it running now using 64 bit distros in windows 10. thanks to everyone else for your advise and help. Mel 2 Quote Link to comment Share on other sites More sharing options...
goretsky Posted July 6, 2017 Share Posted July 6, 2017 Hello, In that case... it sounds like the computer was missing a hardware feature required for Hyper-V. Here are the system requirements for it: https://docs.microsoft.com/en-us/virtualization/hyper-v-on-windows/reference/hyper-v-requirements.
