  • no worries! you want a separate boot partition on your hard disk to make this all easier. if you don’t have one already, I would make one, then go back through the arch install. at the end, there should be instructions on how to update the grub.cfg for arch. you’ll need to do the exact same thing for Ubuntu. the only hard part is that Ubuntu is set up right now to not mount a /boot partition so when you install updates, the updated boot images won’t get installed in the right place. so you need to boot into Ubuntu first and change /etc/fstab so it mounts the boot partition to /boot. then you need to run:

    sudo update-bootloader --refresh
    

    then you can go back and do the arch install with the same /boot partition and run grub-install. there’s detailed instructions on how to change the boot partition here and the ArchWiki should have the rest.
