Really?
didn't knew that one.

If you have an installed windows 8 with secure boot, and then disable 
secure boot, windows 8 won't boot without full reinstall?
Can you confirm that?
Do the opposite also applies? (Installing without secure boot, and then 
enabling it)

Can someone explain (or post a link) on why is that, what makes it 
different that windows can't boot after changing this option?
