Grub Problem - /boot doesn't look like an EFI partition

Hi, I've been trying to dual-boot my Win10 laptop with Arch Linux.
I decided to use the ESP already created by Windows and mount it to /boot. However, after trying grub-install, I get this "/boot doesn't look like an EFI partition".. I've been searching but I couldn't find a solution for this in other related topics.

Some of the commands executed:

To mount the ESP (sda2 = win EFI System Partition)

mount /dev/sda2 /boot

Change root

arch-chroot /mnt /bin/bash

Install grub

grub-install --target=x86_64-efi --efi-directory=/boot --bootloader-id=grub

Can someone help me with this?
Thanks in advance

Re: Grub Problem - /boot doesn't look like an EFI partition

mounting it to /boot outside the chroot isn't going to work.

Really? But I just followed the wiki... I mean, Partitioning, Formating and Mounting is before changing root to /mnt.
Even in the partitioning related posts where I learnt that I could use the ESP created by Windows there's no info related to mount after chroot.

Anyway.. Then I just need to mount the ESP after chroot?

You're setting up the new system in /mnt. Everything, including mounting partitions, needs to be done in /mnt. The wiki mentions other partitions, it doesn't say to mount it at /boot.

Then I should create /mnt/boot and mount the win ESP partition there?
Sorry I'm a bit confused..
