Now we are going to move on to the most important part of this discussion. If you get “This kernel requires an x86-64 CPU, but only detected an i686 CPU. Unable to boot - please use a kernel appropriate for your CPU” this error means you need to enable hyper-v in your machine. First of all go to windows features and check whether hyper-v is ticked or not

Sometimes you may need  to enable hyper-V  in BIOS too ,for more information (http://h30434.www3.hp.com/t5/Desktop-Hardware/How-to-Enable-Intel-Virtualization-Technology-vt-x-on-HP/td-p/3198063 ) Let’s meet with another post No More VirtualBox with windows 8.1
