LinuxBSDos.com published a manual disk partitioning guide for the KDE edition of Linux Mint 17

The installer has automatic and manual disk partitioning options, with support for UEFI systems, which means that the installer is able to create partitions based on an MBR or a GPT partitioning scheme. In the automated mode, there’s support for creating plain-vanilla (no encryption) LVM partitions, and also for encrypted LVM partitions.
