I have read many tutorials and guides, that try to explain how to have two OSes Kali and Raspbian (Wheezy) in the Pi using Berryboot. The problem is that I do not know how, where and when to install Berryboot, this is after or before installing NOOBS or Kali.
I tried two ways to achieve this.
First I copied NOOBS in the pi first. After pluging it to a display, mouse and keyboard and connecting it to the power supply, it asks if I want to install (i) NOOBS in the pi and that would erase the whole content of the sd card.
At this moment I understood that NOOBS itself does not allow to create partitions on first boot.
(in another instance)
Second I tried to install Kali first, because I thought it probably allow me to create partitions once installed in the Pi in the case Kali have not used the whole sd card storage. Unfortunately it does.
I hope you understand me, I tried my best English!
PS: I do not care if you suggest me not to use Berryboot, the main problem is dual-booting Kali and NOOBS. And it is not needed to answer all here, a useful webpage link would be really appreciated.
