How to get to the GRUB menu at boot-time?
This issue came up recently for me (and I've been prompted to lodge it as a specific question about it):
My system is not dual-boot, I run a standard Ubuntu desktop system "on the metal" (I think running it in a VM is the same).
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?

+1 excellent question to expose an essentially undocumented feature of Ubuntu boot process, the answer to which I only found by accident while groveling through grub.cfg. Thanks for hoisting this up to the top (Googleable) level.

(so credit to him.... and I'm happy to bask in the reflected glow ;) I can see the value of it being a primary Q/A.

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.

- Keep hitting Shift until you see "Grub Loading Message"
- After the message, hold the Shift down until the menu appears.

In Ubuntu 18.04, there is no GRUB_HIDDEN_TIMEOUT=0 line in /etc/default/grub - instead there is GRUB_TIMEOUT_STYLE=hidden. According to info -f grub -n 'Simple configuration' :
if this option is unset or set to 'menu', then GRUB will display the menu and then wait for the timeout set by 'GRUB_TIMEOUT' to expire before booting the default entry. Pressing a key interrupts the timeout.
So if you either remove or comment out the line as:
#GRUB_TIMEOUT_STYLE=hidden
then the menu will show by default.

I've heard Shift does it.
But I've used Space before and it worked.

If you can't use shift, try escape. Seems to work for me with Ubuntu 12.10.

By default, GRUB will show the menu if there is a second operating system installed. If only Ubuntu is installed, then GRUB will generally load Ubuntu without showing the menu. To reconfigure GRUB to always show a menu:
Edit
/etc/default/grub:
Set
GRUB_HIDDEN_TIMEOUT=(no value after the=sign).
SetGRUB_TIMEOUT=nto show the menu for n seconds.
- Run
update-grubto regenerate/boot/grub/grub.cfgbased on the/etc/default/grubsettings.
You can get GRUB to show the menu even if the default GRUB_HIDDEN_TIMEOUT=0 setting is in effect:
- If your computer uses BIOS for booting, then hold down the Shift key while GRUB is loading to get the boot menu.
- If your computer uses UEFI for booting, press Esc several times while GRUB is loading to get the boot menu.
Hopefully this clears up confusion as to why Shift works for some users and Esc works for others.

I have tried both the Shift and Space keys but nothing works. Only the Esc key works for Ubuntu 14.04 and 16.04 to get Grub Menu at boot time.

The same for Ubuntu 16.04 - only Escape works. This should be mentioned in documentation (Recovery Mode)

I had to repeatedly press the ESC key, not hold it down. Let's have 6 ways to do the same thing. Linux is fun.

- Keep hitting Shift until you see "Grub Loading Message"
- After the message, hold the Shift down until the menu appears.

In Ubuntu 18.04, there is no GRUB_HIDDEN_TIMEOUT=0 line in /etc/default/grub - instead there is GRUB_TIMEOUT_STYLE=hidden. According to info -f grub -n 'Simple configuration' :
if this option is unset or set to 'menu', then GRUB will display the menu and then wait for the timeout set by 'GRUB_TIMEOUT' to expire before booting the default entry. Pressing a key interrupts the timeout.
So if you either remove or comment out the line as:
#GRUB_TIMEOUT_STYLE=hidden
then the menu will show by default.

I've heard Shift does it.
But I've used Space before and it worked.

By default, GRUB will show the menu if there is a second operating system installed. If only Ubuntu is installed, then GRUB will generally load Ubuntu without showing the menu. To reconfigure GRUB to always show a menu:
Edit
/etc/default/grub:
Set
GRUB_HIDDEN_TIMEOUT=(no value after the=sign).
SetGRUB_TIMEOUT=nto show the menu for n seconds.
- Run
update-grubto regenerate/boot/grub/grub.cfgbased on the/etc/default/grubsettings.
You can get GRUB to show the menu even if the default GRUB_HIDDEN_TIMEOUT=0 setting is in effect:
- If your computer uses BIOS for booting, then hold down the Shift key while GRUB is loading to get the boot menu.
- If your computer uses UEFI for booting, press Esc several times while GRUB is loading to get the boot menu.
Hopefully this clears up confusion as to why Shift works for some users and Esc works for others.

+1 excellent question to expose an essentially undocumented feature of Ubuntu boot process, the answer to which I only found by accident while groveling through grub.cfg. Thanks for hoisting this up to the top (Googleable) level.

Credit where credit is due... This issue came up in another question of mine (buried deep in the comments). Jorge Castro suggested that it would be a good idea to present as a question it its own right... (so credit to him.... and I'm happy to bask in the reflected glow ;) I can see the value of it being a primary Q/A.
