After running Update Manager, a debconf window (titled "Configuring grub-pc"), popped up, requiring me to select the appropriateGRUB install devices
for my system. I've made no changes to grub or the filesystem recently, and I don't remember what options I selected last time I did make a change.
How do I know what to select? I'm assuming the wrong answer could render my system unable to boot.
Here's the debconf dialog:
Here's the window and text that is displayed when selecting "help" :
/dev/sda
lsblk
, the drive that has the/
mountpoint (root) is the boot disk. It may be a partition (ending in a number like sda1). Use this partition's disk (by removing the number, /dev/sda in this case). If you left the menus and are unsure if you wrecked your system, rundpkg-reconfigure grub-pc
. I took all the defaults and selected the disk that had the root-partition on. The system rebooted okay.
