Can you boot the system in single user mode? The prompt on the console is root user.
I would guess not, but I do not know for sure.
If not you will have to find a way to boot using other media like a DVD or maybe a USB stick. Then mount the system drive as something else.
Either way: edit whatever you changed.
Consider creating alternate boot environments just for this kind of thing.
