I had the similar problem the first time I ran quickstart on my system. So, after surfing for a while I realised that I need to change BIOS settings for Virtualisation, which I did and as a result quickstart ran fine. But now, when I am opening the virtual machine after 2 days, its giving me similar issues only this time the Virtualisation is enabled in my system. Could you tell what could be the reason for this?    Thanks in Advance.  ... View more
