Indian captain Mahendra Singh Dhoni won the toss in overcast conditions and sent the West Indies in to bat in a key Champions Trophy match at the Oval on Tuesday.
With both teams having won their opening matches, the winner is almost certain to book one of the two semi-final spots from group B.
India retained the same side that defeated South Africa in Cardiff last Thursday.
The West Indies were without wicket-keeper Denesh Ramdin, who was handed a two-match ban for claiming a dropped catch during his team's victory over Pakistan at the Oval on Friday.
Former captain Darren Sammy replaced Ramdin in the side, with opener Johnson Charles picked to keep wickets.
