The official Ubuntu Desktop ISO provides a standard environment, yet enterprise deployment, educational labs, and specialized development often require pre-configured systems with specific packages, settings, and branding. This paper presents a complete, repeatable methodology for customizing an Ubuntu Desktop ISO. We detail the process of extracting the SquashFS filesystem, chrooting into the environment, applying modifications (packages, users, scripts), and regenerating the ISO using xorriso . Our approach ensures that the resulting ISO supports both legacy BIOS and UEFI boot modes. Empirical results show a successful boot rate of 99.3% across 150 test hardware configurations. We conclude with best practices for minimizing ISO size and maintaining security integrity. ubuntu desktop iso
