At its WinHEC hardware conference in Shenzhen, China, Microsoft talked about the hardware requirements for Windows 10. The precise final specs are not available yet, so all this is somewhat subject to change, but right now, Microsoft says that the switch to allow Secure Boot to be turned off is now optional. Hardware can be Designed for Windows 10 and can offer no way to opt out of the Secure Boot lock down.
The presentation is silent on whether OEMs can or should provide support for adding custom certificates.

Given the number of people who downgraded from Vista to XP and later upgraded from 8 to 7 (Going from Windows 8 to Windows 95 would be an upgrade as well for that matter), it wouldn't surprise me if the hardware manufacturers that force only Windows 10 would face some serious problems.
Quite frankly, any computer that is unable to start any binary and hardware-compatible operating system is defective. Period. I would gladly RMA any product if it could only boot Windows 10, even if I didn't want to install another OS on it.
