If I'm not mistaken couldn't you just mount your already configured grub bootloader to /mnt/boot?
For example, during the arch install if your grub is at /dev/sda2, couldn't you do mount --mkdir /dev/sda2 /mnt/boot?
Somebody who knows more than I do can definitely jump in here as well! But could give that a try
