I, like this guy also accidentally whacked my /etc/default/grub file, though I did it by using > instead of >> in a configuration script. The provided answer looks different from what I remember in the 14.04 desktop default grub file...what does it contain?

Teaching to fish...is there some resource/method I could use to find the answer myself without having to do a 14.04 reinstall just to find out?

There is still an answer possible to the part of the question "Teaching to fish...":

... could use to find the answer myself without having to do a 14.04 reinstall just to find out?

I did a search for /etc/default/grub on http://packages.ubuntu.com/#search_contents:

Sorry, your search gave no results

Stripped the first /etc, so the second source package name search is for /default/grub. The results give a hit:

/usr/share/grub/default/grub grub2-common

Do I have this file still on my Ubuntu machine?

$ ls /usr/share/grub/default/grub

/usr/share/grub/default/grub

or, for example:

$ [ -f /usr/share/grub/default/grub ] && echo Found || echo Not found

Found

As a matter of fact, it is there.

And what are its contents?

$ cat /usr/share/grub/default/grub

# If you change this file, run 'update-grub' afterwards to update

# /boot/grub/grub.cfg.

As you might have spotted there is one more obvious different line compared to the output from Rinzwind's answer:

#GRUB_HIDDEN_TIMEOUT=0

Here you go:

# If you change this file, run 'update-grub' afterwards to update

# /boot/grub/grub.cfg.

# For full documentation of the options in this file, see:

#   info -f grub -n 'Simple configuration'
