Controversial Windows 8 Secure Boot Feature: FSF Issues Rallying Cry

As I said before, so long as the Off switch is a required part of the specification, and the specification specifically states that the operating system may not disable features if it's turned off (or more specifically that the OS cannot disable features if secure boot is disabled, software is installed, and secure boot is re-enabled. I.E. The operating system may not disable features if it detects that it or other OSes were installed outside of a secure boot enabled, signed installer) then it's a non issue.

Otherwise it's a potential cash grab.

 

Windows 8 Secure Boot Feature: Not So Secure?

So Linux is switching to secure boot also? Or they have to because of UEFI?

 

Enabling secure boot on fresh install?

Hello, I apologize if this is the wrong section to ask this. I just bought a blank laptop (ASUS Strix Scar GL503GE) and installed Windows 10. I turned off secure boot for the install because the machine wouldn't boot from the usb. Install went smoothly
but when I went back to enable secure boot, I get "Invalid signature detected. Check Secure Boot Policy in Setup." It boots with secure boot disabled so I still have a working machine. After a bunch of searching online not finding much I tried resetting the
factory keys which works for Platform Key and Authorized TimeStamps but Key Exchange Keys and Authorized Signatures are listed as "External" and attempts to reset them just get the message "Security Violation." What do I need to do to get secure boot working?
