It's still not clear to me why you ran grub-install in the first place, though. What made you do that?
If you change configuration, the right tool to run is update-grub, there is no need to reinstall grub. If you change the ESPs, you use dpkg-reconfigure, so you would not have stumbled across that. I can't really imagine a reason to run grub-install. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1876974 Title: Support multiple ESPs To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/1876974/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
