This happened to me once before, but on a recent reinstall of bluefin:gts the grub menu where you can choose which image you want to load no longer shows up and it jumps right to luks. Last time I think I found a command I entered in the terminal which made it show up again, but this time my google-fu is failing.
Has this happened to anyone else? Any ideas how to bring it back?
you can configure this with ujust configure-grub. You can choose between always show, always hide, and intelligent hide (the default).
The default behaviour is for grub to only show up when there is a failed boot (determined by an incomplete shutdown). You can also force grub to show by hitting escape in the moments between the bios loads and before the initramfs is loaded.
