what you require comes close to going into (former) runlevel 3: Select your boot instance in grub2, type e (for edit) and add "3" at the end of the line. Then continue booting.
I'd say what he asked for would have been achieved with run level one (otherwise known as single), not three. Run level three requires a password, run level one does not.
If you can still boot into run level one, then typing a numeral one, instead of 3, as you've suggested, ought to work.
The old run level one (whatever they call it, these days), was a basic, isolated from the network, text-only, login. But I haven't tried that on a modern system, to see whether it boots up similarly, or into a newer special login.
