I am running Ubuntu GNOME 15.10 with GNOME 3.18 and in the past at random seemingly there was a period in which when starting up my computer I would get the GRUB options which would allow me to choose between launching Ubuntu
, Advanced options for Ubuntu
, System options
, etc…
Now however I just get a strangish gray screen with a border which is darker than the middle and then verbose console output, is there any way to force this options selection at startup? Because if I ever need to access it seemingly only causing my machine to have a cold shutdown during startup will do it which is not ideal…

To force it to come up every time, you need to edit the file
/etc/default/grub
for example withcomment out the line
GRUB_HIDDEN_TIMEOUT=0
so it looks likeor if you do not have that line, comment out
GRUB_TIMEOUT_STYLE=hidden
and make sure
GRUB_TIMEOUT
is set to something above 0 and enough seconds for you to do something when you get to the screen, for exampleSave & exit.
After changing this file, you have to run this command to make changes effective:
(I figured this out by reading the documentation but this popular answer also explains it)
