Cannot detect your distro, you will need to run `grub-mkconfig` (as root) manually.
Common ways:
- Debian, Ubuntu, Solus and derivatives: `update-grub` or `grub-mkconfig -o /boot/grub/grub.cfg`
- RHEL, CentOS, Fedora, SUSE and derivatives: `grub2-mkconfig -o /boot/grub2/grub.cfg`
- Arch, Gentoo and derivatives: `grub-mkconfig -o /boot/grub/grub.cfg`
