VirtualBox Error on Kali Installing

Hey guys, my first post here and till now i was just a ghost :P

well, i dropped here from a serie who got my attention called "hack like a pro" and really got involved in that thing

Then, I decided to try, but don't want to use linux as my first SO by now, so i decide to emulate one on virtual box following a tutorial called "How to install Kali Linux V2.0 sana in virtualbox", posted on a site called hackercool (just in case that u guys need to see the tutorial, not sure if can post external link here, so i gave the information for u google it)

Folowed the tutorial, downloaded kali 2016 32bits on oficial website and did the same with virtualbox, but when i start kali on virtual box it open normally , like the SS show
