Open-sourcers suggest Linux secure boot block workarounds
The Linux Foundation has published a how-to guide for PC makers on implementing UEFI's Secure Boot functionality without preventing the post-sale installation of Linux on Windows 8 machines.
UEFI (the Unified Extensible Firmware Interface) secure boot specs currently under discussion would mean PCs would only boot from a digitally signed image. The framework is designed to guard against malware, most directly rootlets that activate as a PC boots. However critics argue the approach would effectively make it "impossible" to run “unauthorised” operating systems such as Linux and FreeBSD on Windows 8 PCs.
