Rather, it is a symptom of the installer failing to locate its own installation source due to improper boot media preparation, BIOS settings, or virtual machine configuration. By writing the ISO correctly, adjusting firmware settings, or switching to NetInstall, users can bypass this misleading error and successfully deploy RouterOS. Understanding this quirk highlights the importance of flexible troubleshooting: error messages, however outdated, often point to underlying boot or media recognition issues that are solvable with modern methods.
