Each time i start Kali from ISO into Virtualbox, it gets stuck at loading in the same screen.

This happens with Virtualbox 5.1.12

And this with Virtualbox 5.1.14
VirtualBox_Kali 2016.2 i386_19_01_2017_02_45_36.jpg

Before that, download the Kali VirtualBox image and got another error that cannot solve either (VERR_VMX_NO_VMX) because, i think, my pc is old.
My pc: Acer Aspire 5738 (Intel Core2 Duo T6400) with Windows 8.1 Pro.
