Running VirtualBox on a Windows 8.1 host

All we need is an easy explanation of the problem, so here it is.

I have a Windows 8.1 Pro 64-bit machine, with an Intel Haswell i7 processor, and 8GB of RAM.

I installed the latest VirtualBox (4.3.6) and I’m trying to install a Linux guest. I’ve tried several Linux distribution ISOs (Mint16, Mint16-xfce, Fedora20, Kubuntu13.10), and they all get stuck right after the Live CD boots. I managed to install some of them on my VirtualBox on the Mac, so it’s not the ISOs fault. Something is preventing the boot sequence. Any ideas?

How to solve :

I know you bored from this bug, So we are here to help you! Take a deep breath and look at the explanation of your problem. We have many solutions to this problem, But we recommend you to use the first method because it is tested & true method that will 100% work for you.

Method 1

Finally found the answer. It all hinges on Hyper-V and the fact that it’s enabled by default in Windows 8.1 Pro (as well as in other Pro and server Windows versions). With Hyper-V running, other hypervisors (like VirtualBox, VMWare and Android emulator) are crippled.

You could, potentially, disable Hyper-V from the Windows Add/Remove Features dialog. But what if you use Hyper-V for development or testing (i.e. WP8 development)?

The solution is to boot Windows with Hyper-V turned off. And the easiest way to do it, is to create a new boot configuration, with Hyper-V off, and boot to it whenever you need to use VirtualBox.

There are several step-by-step guides on how to create a new boot configuration – this one has some screen shots.

Note: Use and implement method 1 because this method fully tested our system.
Thank you 🙂
