Once I unlock the drive, I get the same error for EFI “mount: /mnt/boot/efi: mount point does not exist.
dmesg(1) may have more information after failed mount system call.”
What does ls /mnt and ls /mnt/boot show?
Oh, I see. Your efi partition isn’t mounted at /boot/efi. It is mounted /boot
ls /mnt
ls /mnt/boot
You probably need this from where you are now:
sudo mount /dev/sda1 /mnt/boot
sudo arch-chroot /mnt
grub-install --efi-directory=/boot
WOOOOW DALTO 
It worked!
I completed that.
Anything else to install?
No, that should be it.
Good to reboot?
btw how did you figure out the sudo mount /dev/sda1 /mnt/boot ?
Your /etc/fstab
Any need to do the following?
grub-mkconfig -o /boot/grub/grub.cfg
grub-install --target=x86_64-efi --efi-directory=/boot/efi --bootloader-id=GRUB
Although your /boot is kind of a mess. It seems to also have all the things /boot would normally have…
No
What in the world is this?

Sorry I meant, shouldn’t it load my OS?
Typically, I would get a screen to enter crypt paraphrase…
Something is very strange. First go into your BIOS and ensure the right entry is selected as the default.
If it is, go back into the chroot and lets see what is in your efi partition.
This might be the culprit
I added this using the arch wiki and I probably did it wrong

My machine is Lenovo m93p but followed what was suggested for M92p
Should I follow above steps and chroot into /mnt/boot?
