From Metal Gear Wiki's topic on Big Boss:
Big Boss's body was recovered by the U.S. Government and it was discovered that he was, in fact, alive. He was injected with nanomachines to induce a sort of eternal coma. For Zero, Big Boss was an irreplaceable icon and more importantly, an irreplaceable friend. Big Boss' genome was then used to discover "soldier genes", which the US government gave to the Next Generation Special Forces via gene therapy.
To further make the world believe he had died, a grave was laid next to The Boss' grave which read: "A Hero Forever Loyal To The Flames Of War, Rests In Outer Heaven. 193X - 1999"
Although badly burned, his body was much later recovered by EVA who put him back together using pieces of his cloned sons, Liquid and Solidus. When she was finished, Big Boss looked as though he had never been burned.
