Hi guys, I have only ever really used windows (and acorn computers if you count those lol from the 90s/early 2000s).

I wanted to try out unix and linux since they seem to be important for people who into computers and programming and cyber security etc.

I dont really get the difference between Unix and Linux, and the difference between Ubunto, Kali Linux etc either.

I wanted to install everything I would need on my laptop. Can I triple boot my laptop so that I can run both linux and unix? what is the difference betwenen ubuntu and kali linux?

Is there another way to run two operating systems rather than double booting?

And overview of this stuff would be much appreciated.

Cheers
