How to uninstall kali?

Ok, so I have 3 kali installs(1 because of glitch in my pc, another trying to reinstall because of auto login making kali not boot)
And I don't know what partition its on..
so how do i do it via recovery mode.

Or is there a program to find the debian partition.

Thanks,

Boot Kali live and run gparted.

You will be able to see all your drives.

As for which one is Kali... Mount each partition in Kali live, check it and move to the next one.
