You May Not Be Able To Install Linux On Windows 8 PCs
“Windows 8 PCs will boot super fast in part because of the next-generation booting specification known as Unified Extensible Firmware Interface (UEFI).
The latest UEFI, released April 8, includes a secure boot protocol which will be required for Windows 8 clients. Secure UEFI is intended to thwart rootkit infections by requiring keys before allowing executables or drivers to be loaded onto the device.
Problem is, such keys can also be used to keep the PC’s owner from wiping out the current OS and installing another option such as Linux, says Matthew Garrett, a mobile Linux developer at Red Hat, in a blog post.
If a vendor key is installed on a machine, the only way to get code signed with that key is to get the vendor to perform the signing. A machine may have several keys installed, but if you are unable to get any of them to sign your binary then it won’t be installable. … Microsoft requires that machines conforming to the Windows 8 logo program and running a client version of Windows 8 ship with secure boot enabled.
