사용자에게 답변하기: Why I can't select boot order?sorry to revive an old thread, but i've got the same problem today. i installed windows 7 via bootcamp like 2 weeks ago and was running normal. this morning, when i reset mac os and press the option key, it won't do anything, it just boots as mac os again, it won't even show the recovery partition. keyboard and option keys are working ok when i type. the only thing i could think of is that i installed the loader to get rid of the validation, maybe i corrupted something? should i try to reinstall windows or is some method to repair it? thanks!
