I swapped out my HDD for a Samsung 840 EVO SSD, and migrated my OS using Samsung's Data Migration Program. I had Visual Studio 2013 installed with the Windows Phone SDK 8.0, and I was able to run all emulators normally on the HDD. However, the emulators will not start on my SSDs, and I'm getting the message "hypervisor isn't running". I have hardware virtualization enabled on my BIOS, is it just that the emulators won't run on the SSD?

You miss the BCD entry to load the Hyper-V driver. Open a command prompt as admin and run this command:

bcdedit /set {current} hypervisorlaunchtype auto

reboot and the Hypervisor driver is loaded.
