Difficulty: Moderately Easy
Step1
Consider the type of computer needing the operating system. Older Apple computers will only accept an Apple operating system version. Likewise, older Windows systems won't accept Apple operating systems. Newer computer systems may operate both platforms.
Step2
Think about what type of software and applications will run on the new operating system. Graphics programs, like Adobe Creative Suite and Corel Suite, require a substantial amount of operating system attention. Most creative art houses and publishing firms have until recently used Apple operating systems as their operating system of choice.
Step3
Look into alternative operating systems, like Linux or user-created operating systems. These offer flexibility to the user to experiment and develop applications specifically for that operating system.
Step4
Understand that most software applications and device drivers use the Windows operating system. Worldwide, Windows computers vastly outnumber all other types of operating systems. Stepping outside this convention produces problems finding applications to run smoothly on other operating systems.
Step5
Install Sun's Solaris operating system for a clean and small operating system footprint. This alternative operating system is free and has a seemingly endless array of software available for installation. The development team for Solaris provides a great system of support for the end user as well.
