[tlug] UEFI Partition for New Debian Install

[CL <az.4tlug@example.com>]

New (for me) problem.  My in-box backup HDD went Tango Union 
(thankfully, just after a full transfer to offline storage) on the same 
day PC Depot was having a sale on new ones.  So, I'll be installing 
Debian 9 and transferring the existing Debian 8 disk to backup duty 
after I copy off all the ongoing stuff.  Except the EFI partition I've 
set up on the new HDD is not being recognized by the Live CD installer.

I set up a 3Tb HDD using gpt with GParted and checked with fdisk:

sda1 = EFI System (FAT32), boot and esp flags are set

sda2 = ext4

When I attempt to install Debian 9 in the ext4 partition, it fails due 
to missing boot space.  I've tried formatting the HDD during setup but 
it appears as though it wants to wipe the entire disk and format it as a 
legacy device.  Since I don't yet have an installed system, installing 
grub-efi isn't possible.  Do I need to further define the use of the EFI 
system partition using fdisk?  I have found a couple of hints in that 
direction from non-Debian sources.  Most of the answers I find online 
seem to want me to know that if I'd just install Windows 10 first this 
would all be taken care of automatically.

Update to a previous post:

My work system is up and running.  You may have noticed a recent sharp 
dip in the world's supply of Stupid.  The fix for my non-working system 
was to take all the components back out of the box, disassemble 
everything, re-check for bent pins,  dirty contacts, and mounts, wipe 
all male contacts with contact cleaner, then reassemble s-l-o-w-l-y.  
And it worked.

So, I have a working system and absolutely no idea why I didn't 
previously.  But, it does now.
