How to get GRUB options selection on startup?












2















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 with



sudo nano /etc/default/grub


comment out the line GRUB_HIDDEN_TIMEOUT=0 so it looks like



#GRUB_HIDDEN_TIMEOUT=0


or if you do not have that line, comment out GRUB_TIMEOUT_STYLE=hidden



#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 example



GRUB_TIMEOUT=10


Save & exit.



After changing this file, you have to run this command to make changes effective:



sudo update-grub


(I figured this out by reading the documentation but this popular answer also explains it)

    If you're running a PC selecting F12 during bootup will take you to the boot options section. If you go to boot-order, or something like that, and push the GRUB boot manager to the highest priority. It should boot to GRUB first after that. If you're running a Mac, it could be the same, but I've never used OSX so I don't actually know.
