In security’s name, Microsoft has made it difficult to install Linux, or any other operating system, including older versions of Windows, on Windows 8 PCS. In addition, Microsoft has made it all but impossible to install Linux on Windows RT devices such as the Surface RT.
Microsoft has done this by adding a feature to UEFI (Unified Extensible Firmware Interface), the next generation of BIOS, called secure boot. Its avowed purpose is to prevent rootkits, malicious programs that run before the operating system boots, from running.
So far, so good as even the Free Software Foundation (FSF), an organization with no love for Microsoft recently admitted.
