I have a dell Latitude 3330 Laptop and I just installed a 250 GB ssd but the laptop already has a 64GB ssd installed internally somewhere that I cant get to. The old ssd already has Mint Installed But I want to install Kali on the new ssd. Is it possible for me to just simply set up a dual boot situation? or can I just used the old ssd as boot up and the new ssd as storage? if I have to do the later how do I do That?

I'd rather Just have a dual boot situation, AND I HATE WINDOWS so dont tell me I can only do it with windows please...

Please read the Kali install instructions and the usage documentation on the Kali web site
