Good news is I got the usb key to work. Holy shit it boots in like 2 minutes instead of 20. I'm never burning isos to dvds again. I'm so old fashioned I'm still from the knoppix days. This is awesome.
Ok I should show you the boot order (have I yet?):
Notice there are two ubuntu's- actually it was like that even before I did the reinstall. I can't remember why but when I did the original install last year I did something by accident and made two. But anyway just now I attempted both and got the same results with both.
I don't see anything that stands out other then your missing /boot/grub/x86_64-efi directory.
Might be something wrong with the initramfs in /boot. Follow this tutorial https://linoxide.com/linux-how-to/fi...d-image-linux/
after mounting your root partition to /mnt mount the efi partition to /mnt/boot/efi before running the mount --bind commands.
before exiting out of the chroot run
root@ubuntu:/# ls /boot/*initrd*
/boot/old-initrd.img-5.0.0-23-generic /boot/old-initrd.img-5.3.0-28-generic
so I renamed them both to old.[]
Oh wait it says that's only for centos and fedora; the red line. Even still... it's a mistake. Anyway I moved on using the debian version, but I didn't know which one to use since there's two so I assumed the newer version:

Anyway I went ahead and did it anyway and it looks like it did some EFI magic anyway:
Code:
root@ubuntu:/# update-grub

Alright well I hope you're asleep! Tomorrow I guess I'll just reinstall and map the efi drive properly this time; that's the next thing to try. Unless you want to keep going tomorrow as an exercise, I'm willing, I'm learning a lot. gnight thanks so much,
exit
The echo commands appends nameserver line to your /etc/resolv.conf
Oh yea I should've thought of that- the reason apt-get couldn't resolve the package is just because there's no dns. Btw I didn't know that echo could actually change a file; I thought it was just for displaying and changing env variables.
oohhhh right- I need to do the "for i in /dev /dev/pts /proc /sys /run; do sudo mount -B $i /mnt$i; done" thing from stackoverflow again first, right? I thought those were mutually exclusive. So I do that procedure first before the initrd tutorial?
Oh ok all I had to do was mount the efi. Ok I just did it (outside of chroot in a different window), but it worked without complaining:
Code:
root@ubuntu:/# apt install grub-efi

grub-efi is already the newest version (2.02-2ubuntu8.14).
The following package was automatically installed and is no longer required:
grub-pc-bin

root@ubuntu:/# grub-install
Installing for x86_64-efi platform.
Installation finished. No error reported.
Should I do the rest of the tutorial over? (It's all already written to disk right), or should I skip to the end-
