Linux Mint Debian Edition, or LMDE, is the edition of Linux Mint based on Debian Testing. The latest release was made available for download on December 24, 2010. The installation program on this edition is similar to the Ubiquity installation program, which is used on the main edition, the one based on Ubuntu. But while the Ubiquity installation program incorporates an automatic disk partitioning phase, the LMDE lacks it. As a result, installation of LMDE requires that the disk be partitioned manually . This tutorial offers a step by step on how to partition a disk for installing LMDE.
