Yes, and this (but see below for the resulting grub.cfg) looks like
more trouble:
home-desktop# grub-mkconfig -o /boot/grub/grub.cfg
Generating grub configuration file ...
Found kernel of FreeBSD: /boot/kernel/kernel
Found kernel module directory: /boot/kernel
grub-probe: error: cannot find a GRUB drive for /dev/da0p1. Check
your device.map.
grub-probe: error: cannot find a GRUB drive for /dev/da1p1. Check
your device.map.
done
I don't have even the first idea why it's looking for /dev/da0p1 or
/dev/da1p1. I've tried both creating /boot/grub/device.map with just
an entry for /dev/ada0 and deleting it.
I managed to copy in the EFI directory from my other local system. I'm
in the middle of stuff right now, so I haven't yet tested this.
grub-mkconfig does, however, create /boot/grub/grub.cfg which, among
other things, appears to contain entries (see below) for Windows (and
Dell) stuff.
And grub-install appears to work:
home-desktop# mount /boot/efi
home-desktop# grub-install --target x86_64-efi /dev/ada0
Installing for x86_64-efi platform.
Installation finished. No error reported.
home-desktop# ls -al /boot/efi/EFI

One thing that is surprising is that I am no longer having to switch
the partition type back and forth between bios-boot and efi. I don't
know what changed here--oops.
grub.cfg contains:

I'm hoping for the best. As soon as I get through with all this other
stuff, I'll attempt a reboot and see if I can actually get into 1)
grub, and 2) Windows. The latter, as previously mentioned, might fail
because the files I copied in are from Windows 8.1 rather than Windows
10.
I do have another Windows 10 installation lying about but I haven't
found how reliably to get into the firmware to boot it under something
else that will let me actually copy the files from its EFI partition.
This other system is a super-cheap Asus laptop and Google is not being
my friend.
