So let me get this straight. You are saying that you can make changes
to the MB ROM/EPROM/whatever hardware the vendor uses, by issuing an
erase command on a hard drive? I'm having a bit of trouble believing that.
You might be able to trash the system on the HD to a point that it is
unrecoverable. I will believe that.
When you're done trashing the system you just have to reinstall the
system just like you would with a clean new HD.
All that UEFI crap is built into the MB in Read Only hardware. A new HD
does not come with any of the UEFI files or directories already on the
disk. All that is created at the initial install. Blowing them away
with a remove command does nothing to the MB hardware because it's Read
Only hardware.
