How to enable GRUB menu on Ubuntu 12.04 server?

I have an Ubuntu server installed, and no matter what settings do I try to change, the GRUB menu won't appear. It only shows "Booting hard disk ...10... 9..." and that's all!

My /etc/default/grub file.

The /boot/grub/grub.cfg.

It's a KVM guest.

Here's the relevant portion of your pastebin'd /etc/default/grub:

Please comment out these lines in /etc/default/grub by adding a # in front:
```
GRUB_HIDDEN_TIMEOUT=10

GRUB_HIDDEN_TIMEOUT_QUIET=false
```

Save, and then run sudo update-grub

The menu should now appear on every run, with a 10 second timeout for the default entry (0); we just "un-hid" the menu during the timeout countdown.
