Answer 1

A #WilliamLyon indicated:
A new DB has no nodes, and therefore has no node with the ID of 0.
The START clause is now deprecated.
You are apparently using a very old version of neo4j. If possible, you should install the latest version.
In addition:
Nodes now must always be specified within parentheses.
Try the following, instead, which should work with your version of neo4j as well as the latest versions:
CREATE
(tatham {Name:'Tatham'}),
(tom {Name:'Tom'}),
(pat {Name:'Pat'}),
(chrissy {Name:'Chrissy'}),
(sailing {Name:'Sailing'}),
(mtb {Name:'MTB'}),
(rowing {Name:'Rowing'}),
(tennis {Name:'Tennis'}),
(root)-[:HAS_USER]->(tatham),
(root)-[:HAS_USER]->(tom),
(root)-[:HAS_USER]->(pat),
(root)-[:HAS_USER]->(chrissy),
(tatham)-[:FRIEND]->(tom),
(tom)-[:FRIEND]->(pat),
(tatham)-[:FRIEND]->(chrissy),
(tatham)-[:LIKES]->(sailing),
(tatham)-[:LIKES]->(mtb),
(tom)-[:LIKES]->(sailing),
(pat)-[:LIKES]->(mtb),
(tom)-[:LIKES]->(rowing),
(pat)-[:LIKES]->(tennis),
(chrissy)-[:LIKES]->(mtb),
(chrissy)-[:LIKES]->(sailing);
The root node will be created automatically the first time it is encountered by the query, and then re-used.

Answer 2

The problem is the first line of your Cypher query: start root=node(0). That statement is saying "find a Node with id 0", however if you haven't inserted any data yet there is no Node to find, thus the error.
start has been deprecated and is no longer required so you can just remove it.
