GRUB menu doesn't show up after upgrading to Ubuntu 19.04 [duplicate]
After upgrading to Ubuntu 19.04 my GRUB menu doesn't not show up.
Instead, it halts for 10 seconds and then directly boots up to 19.04 although I have installed Windows 10 alongside (Dual booted).
GRUB menu was working perfectly when upgrading to 18.10 from 18.04LTS.
Also, if I press Esc or Shift key it hangs and then I have to press power button to start the laptop again.
i encountered this myself some time back, i don't remember exactly what i did to fix it and i don't have access to a ubuntu system right now to double-check, but iirc here's what i did:
in /etc/default/grub (or was it /etc/default/grub.cfg ? whichever one of those exists)
- make sure
GRUB_TIMEOUTis set to something higher than 0, likeGRUB_TIMEOUT=5 - make sure
GRUB_TIMEOUT_STYLEis set tomenu, egGRUB_TIMEOUT_STYLE=menu - remove all references to
GRUB_HIDDEN
then run sudo update-grub and reboot, and the grub menu should pop up
Probably the Ubuntu 19.04 installation has added its own EFI boot entry, configured to not show the grub menu.
Try this: edit the file /etc/default/grub to make sure the GRUB_TIMEOUT value there is set to something larger than zero, for example GRUB_TIMEOUT=12 if you want the menu shown for 12 seconds. Then run the update-grub command:
sudo update-grub
The output from the update-grub command should say "Found linux image" and if you have Windows 10 installed it should also say "Found Windows Boot Manager". Then reboot, and the grub menu should be shown.
