Hi guys, Sorry if this kind topic has been discussed before, i just have no time to check. So i need your help ASAP. So yes i have bootcamp'ed my macbook to windows 7 34bit. And i think i made a mistake during installing it. Well when given the partition, it was 4 partitions , i chose bootcamp partition, but unfortunately it cant be installed on it, so i tried to format the bootcamp partition, and it's ok, so i have done it. But the problem is, i couldn't get into the mac whenever i restart or shutdown and turn on back. The screen started with, i think silver ( usual colour when mac turned on) Then after afew seconds the screen turned black and windows' basic startup ( i mean like login and etc) I've tried many times by pressing Option when mac started, but it didnt work. Thanks. p/s: sorry, i can't talk english properly.
