Technologies are provided herein for automated operating system installation. Through the concepts and technologies presented herein, the process of installing multiple operating systems on a system under test (“SUT”) can be automated and monitored, thereby permitting the unattended installation of the operating systems. Multiple operating systems can be installed and errors detected during the installations can be logged in an automated fashion, thereby reducing the cost of such testing. Errors generated during the automated installation process can be analyzed and utilized to identify and correct errors in a computing system firmware. A device selector for facilitating the automated installation process is also provided.
