May I ask a couple of questions which I'm afraid betray my ignorance.
1. Why is it advisable to "revert back to UEFI"?
Is this just a safety measure?
I would have thought that if an intruder had got in this far,
enabling him to install unsigned modules,
he would have you at his mercy anyway?
2. I installed CentOS-7.2.1511 from a Live USB stick,
and I have a Windows 10 partition that I can boot into.
So I assume that UEFI is not used by default?
Will it become so at some point?
