How to get to the GRUB menu at boot-time?

My system is not dual-boot, Pressing c while booting does not cause the GRUB menu to appear (which I believe it does for a dual-boot system).

How can I get the GRUB-menu to present itself on a single-boot system?

I believe I have seen this problem before,
Menu will appear if you press and hold Shift during loading Grub, if you boot using BIOS. When your system boots using UEFI, press Esc.

For permanent change you'll need to edit your /etc/default/grub file -- place a "#" symbol at the start of line GRUB_HIDDEN_TIMEOUT=0.

Save changes and run sudo update-grub to apply changes.

This Should Work Also,

Sometime we need to

Edit /etc/default/grub (sudo -H gedit /etc/default/grub)...

change:

GRUB_TIMEOUT_STYLE=hidden

to:

GRUB_TIMEOUT_STYLE=menu

then save the file and quit the editor. Next run:

sudo update-grub
