Secure boot is the sort of security solution Microsoft loves. Back in the days when Windows was even less secure than it is now, one of their security solutions was to have software vetted and signed. Although this might have helped enterprise customers a bit, it did little to make the home user more secure, as any software would still install normally after clicking through an “are you sure” warning. If this scheme did anything, it hurt small vendors who couldn’t afford to go through the process of having their software approved by Redmond.
Secure boot is the same sort of scheme, except this time there’s no “are you sure” screen to click through. If a user is trying to install an operating system (or even run one from a live CD) on a machine with secure boot enabled, that operating system will have to have unlock keys to enable hardware devices. These keys are provided to the creator of the operating system at the whim of the hardware makers.
