title: Edit a file using grub
body: <p>I did a really bad mistake in the rc.local boot file. I added a process with an infinte loop to the list in this file so that my arch linux distro is not able to boot completly because this process blocks the further boot procedure.</p>
  
  <p>Is there a way to edit this rc.local file in grub so that I can remove this process?</p>
