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?

Are you trying to do the 64-bit or 32-bit Linux guests? Is virtualization turned on? What is the EXACT CPU model? Can you load a version of Windows on VirtualBox? –  Canadian Luke Dec 30 '13 at 22:41
    
I'm trying 64-bit for the guests. Virtualization is turned on. CPU model is I7-4500U. Haven't tried Windows on VBox, but managed to install Linux on Hyper-V 9reason I'm not sticking to Hyper-V is the resolution limit). –  Traveling Tech Guy Dec 30 '13 at 22:50
    
Try with a 32-bit guest, just for S&G –  Canadian Luke Dec 30 '13 at 22:51
    
Do you have a hunch? I never had that problem before with VBox (as said I have a Win7 machine happily running Ubuntu64, as well as a Mac doing the same) so before I start downloading more ISOs, I wonder if there's something I may be missing. –  Traveling Tech Guy Dec 30 '13 at 22:54
    
It's going to be the first thing I'd try. I never allocate more than 3GB of RAM anyways to my VMs, so I never use the 64-bit ISOs (except for testing purposes). –  Canadian Luke Dec 30 '13 at 22:59

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.
