Troy is a Linux distribution created in 2004 for Turkish users. It aims to provide a fast, reliable, and easy to use operating system. It has three versions - a foundation version for installing on hard disks, an employee version that runs from a CD, and an improved version still under development. Installing Troy is similar to other operating systems and involves partitioning the disk, then selecting the Linux section for installation. The installation process takes 10-30 minutes to complete depending on the system.
