I need to install Kali from live desktop, but I can’t find the installer. Any idea what I should do?
As mentioned in Why is Kali Linux so hard to set up? Why won't people help me?, if you need to ask about installation, then you probably shouldn’t use Kali Linux. Quoting Should I use Kali Linux? from the official documentation:
As the distribution’s developers, you might expect us to recommend that everyone should be using Kali Linux. The fact of the matter is, however, that Kali is a Linux distribution specifically geared towards professional penetration testers and security specialists, and given its unique nature, it is NOT a recommended distribution if you’re unfamiliar with Linux or are looking for a general-purpose Linux desktop distribution for development, web design, gaming, etc.
To address your question, you can’t install Kali Linux from the live desktop; you need to choose the appropriate option when booting. See the official installation instructions.
Try to burn a DVD and install from there, the problem is that Kali Linux is tought to be used on a virtualization software, that's the way it sucks to ISO over /dev/cdromX.
Once installed it will work as in an VM. But haven't tested, I was researching because I need to install it also in host, and I can't install from grub meny neither from live desktop. So, I supose it's just a lack of implementation while you are able to install it if you successfully use what it asks you: a DVD device from source!
Sure there're other options, but I don't need to research more. Good luck.
I just wanna make a note that at one point in time there was a distribution of kali that had the installer from live environment right on the desktop with the big letters INSTALL, now don't quote me on that as it may have been backtrack 5R3.
Obviously alot of these people like to talk to others instead of helping them out. Its actually very simple to install from a live Kali Desktop.
apt update && apt upgrade && apt install calamares
then you use calamares, which is a gui and the same installer that is on Linux Mint Debian Edition 3.
