Clicking on “install CentOS” on VirtualBox causes black screen to appear?

Solution is to set the Linux version in VirtualBox to be 64 bit!

Hopefully the below links help on 'how to change virtualbox to 64bit, if you do not see any 64bit option in the dropdown menu

{http://www.fixedbyvonnie.com/2014/11/virtualbox-showing-32-bit-guest-versions-64-bit-host-os/#.WCswkrKLRpg}

I followed the steps and it worked for me!

Edit: The problem the link says is that you have Hyper-V installed. Remove roles and features > uncheck hyper-v > wait for wizard to finish > reboot

Try the menu now and you should see 64-bit.
