Virtual box and ubuntu

I was trying to install Ubuntu 15.04 (ubuntu-15.04-desktop-amd64.iso) as a guest system on Virtual box 5.0.0 running on a macOS host system.
The problem I was facing was the install crashing and not able to finish. Looking I found a blog, the solution that worked for me was :
Disabling "Nested Paging" in Setting->System->Acceleration allows to start the system.
