During a routine package upgrade (apt-get upgrade) it prompted me
┌─────────────────────────────────────────┤ Configuring grub-pc ├─────────────────────────────────────────┐
│ The grub-pc package is being upgraded. This menu allows you to select which devices you'd like │
│ grub-install to be automatically run for, if any. │
│ │
│ Running grub-install automatically is recommended in most situations, to prevent the installed GRUB │
│ core image from getting out of sync with GRUB modules or grub.cfg. │
│ │
│ If you're unsure which drive is designated as boot drive by your BIOS, it is often a good idea to │
│ install GRUB to all of them. │
│ │
│ Note: it is possible to install GRUB to partition boot records as well, and some appropriate │
│ partitions are offered here. However, this forces GRUB to use the blocklist mechanism, which makes it │
│ less reliable, and therefore is not recommended. │
│ │
│ GRUB install devices: │
│ │
│ [ ] /dev/sda (2000398 MB; HGST_HUS726020ALE614) │
│ [ ] - /dev/sda2 (1999860 MB; /) │
So what should I choose - /dev/sda or /dev/sda2 (mounted as root and where grub.cfg is) or both? grub.cfg mentions /dev/sda2 by uuid. Where is /dev/sda1 which is mounted as /boot/efi? And how can I run it automatically as mentioned in the second paragraph?
18.04. grub-efi-signed is installed although secure boot is disabled - don't know why the installer did it.
