I am using the Live version of Kali Linux and now I'm realizing that having persistence might be a good idea. There are some tutorials out there showing how it can be done on Windows and it looks easy with tools like Rufus. However the thing is that I have a Multiboot USB containing some other ISOs like one for a live GPARTED distro that allows me to resize all partitions on my computers. For this setup, I am using a tool called Ventoy. Now, Ventoy does support persistence as written here but the instructions were rather difficult for me to follow. I was wondering if I could simply partition the drive myself into two volumes: one for ventoy + GPARTED + Kali and the other for the live Kali persistence? What extra would I need to put in the second (persistence) partition to tell Kali to use that space for its persistence storage?
What would be the best way of going about this. What I finally want is a multiboot USB with two ISOs: one for GPARTED, one for live Kali + persistence, quite possibly in two partitions (or more if required). Any thoughts?
