The writer, whose book Solo is published today, is the latest in a long line of novelists including Kingsley Amis and Sebastian Faulks to continue the adventures of the spy first created by Ian Fleming.
Boyd said he approached the story, which sees 007 embroiled in a civil war in 1969 Africa, as a fan of both the books and films.
He said: "The thing is with the literary Bond, as opposed to the cinematic Bond, is that he's a very complex character. I mean he is a cool, capable, guy and he's a very successful operative but what makes him fascinating for readers is the darker side of him, he's troubled, he makes mistakes.
"I think that three dimensional portrait of him you get in the novels explains why he's not just some cardboard caricature spy, he's a real living, breathing, interesting individual."
Boyd said he had "discussions" with the current 007 about whether he should write the book.
He said: "I knew he was going to say yes."
The writer said it was "highly unlikely" Solo would be made for the cinema.
He said: "It is set in 1969 and the Bond films are always set in the present day. They'll never make a retro Bond."
Boyd added: "If there was to be an actor to play my James Bond, I'd choose another actor who has also been in a film of mine and who is also called Daniel - Daniel Day-Lewis - because I think Daniel Day-Lewis actually resembles the Bond that Fleming describes."
