You are sooo gay for Gordon Ramsey.Cooking a steak depends entirely on the cut. How thick it is, how fatty, how much bone, and so forth. Follow the advice above, but you're not going to get it perfect the first time. It takes practice, but it's fun. And, two large pieces of advice - if you're going to err in one direction, err toward under cooked, not over cooked. And, make sure you let the meat rest a good, long time.
(also, Gordon Ramsay's steak method is best imho)

Same. I order my steak rare at restaurants. Even approaching medium-rare is more done than I like. I find that a typical Ribeye/KC Strip that is maybe 3/4 to an inch thick, I can just sear the shit out of each side for like 2 minutes(either in a cast iron skillet inside, or on a hot grill with the top open) and then they're done to my liking internally(rare). 10 minutes in an oven would put a steak of that thickness up into the medium range of doneness, and that's no good.I don't usually find that putting it in the oven is necessary unless you have a very thick steak. I don't mind my steaks on the rarer side, but even if you're going for a full on medium steak I think putting it in the oven is unnecessary unless it's an inch and a half thick.
