i am going to try the guide inside this question
However, it requires me to boot from recovery mode. But holding the shift key doesn't work for me to go to grub menu.
Anyone know how to troubleshoot this kind of behavior?

I assume that you can't boot into a "normal" session and need recovery mode for repairs...Would it work for you to boot a live CD and make the repairs that way?
