How do I access root terminal in recovery mode that is NOT read only?

I have a blank screen problem on ubuntu 16.04 start up screen. Initially I was repairing my hard disk with fsck /dev/sda1 from this post.

In trying solve the black/blank screen problem on startup, I am following instructions from:

Ubuntu 16.04 [gnome desktop] boots into a blank screen with a cursor on it.

...to use:

chmod 777 /
shutdown -r

etc.

in the 'root terminal' of recovery mode, but it only allows 'read only'. How can I get it into the 'write mode' for this?
