Linux Mint Debian is the latest version of Linux Mint. Unlike other versions of Mint, it is not based on Ubuntu, but rather on Debian Testing, and comes with a brand new installer. Also, unlike the Ubuntu-based versions, the installer does not have an automatic disk partitioning feature – it requires manual disk partitioning with GParted.
This tutorial provides a detailed guide on how to partition a single disk for installing Linux Mint Debian.
