Actually, if I've understood what I've read over the past two weeks,
that's not correct.  You need a dedicated partition formatted in FAT32,
marked ef00 partition-type with the "boot" flag enabled on it. Mounting
that partition on /boot/efi (or somewhere else, depends on the distro)
is a LInux thing.

Best of luck.  I got the last two components of my new system today.
It's my Christmas present to me! No one gives me toys anymore.  So, I
buy them myself. ;-)
