Microsoft requires Windows 8 logo systems to not boot unsigned OS’s

September 21st, 2011

This looks like something to keep an eye on.. Matthew Garrett (the guy who makes peoples laptops work with Linux and has to deal with EFI& Linux – makes you wonder what awful thing he did in a past life) writes about a worrying requirement for Windows 8 logo certification for hardware vendors..

# Microsoft requires that machines conforming to the # Windows 8 logo program and running a client version # of Windows 8 ship with secure boot enabled. The two # alternatives here are for Windows to be signed with # a Microsoft key and for the public part of that key # to be included with all systems, or alternatively for # each OEM to include their own key and sign the # pre-installed versions of Windows. The second approach # would make it impossible to run boxed copies of Windows # on Windows logo hardware, and also impossible to install # new versions of Windows unless your OEM provided a new # signed copy. The former seems more likely. # # A system that ships with only OEM and Microsoft keys will # not boot a generic copy of Linux.
