Now Microsoft Won’t Let You Install And Boot Linux On Locked-down Windows Computers
Found on fossBytes on Sunday, 17 July 2016

In its latest Patch Tuesday security update, Microsoft closed a backdoor left open in Windows RT–Windows 8.x ported to devices with 32-bit ARMv7 processors–computers that allowed developers and hackers to boot non-Microsoft approved operating systems.
A way to bypass Microsoft’s boot mechanism is highly sought because Microsoft is killing the support for Surface RT tablets in 2017 and Windows RT 8.1 in 2018.
That's why locked down hardware is a bad idea. Starting next year, customers will have unsupported tablets and no choice but to throw them away or accept unpachted bugs. Instead, they could install a system which would work and fixes bugs, but thanks to Microsoft this won't be allowed.
