"Read-only file system" has nothing to do with read/write permissions. It means
that the disk has been mounted read-only. "mount" in a command window will
show you the details.
While in the command window, you could see if the system objects to making the
disk read-write. Suppose for example it is mounted as /dev/sdb1. Become root or
mount -orw,remount /dev/sdb1
will either make the disk writable or give you an error message indicating why
