Ok guys, so I've been graduated already like a month ago, they failed to reset the given school laptop... So basically I own a laptop which is mine since i graduated but due to some errors, it couldn't be resetted and I'm not admin on it... like i can't open softwares and certain websites.. you know basic school restrictions... I'm legally allowed to do anything with it. Will getting a sata cable and formatting the harddrive help? does it matter if you're not the admin of that harddrive?(school's the admin)

ps: I have a windows 8 installation disc + product key. so once its resetted I know how to install windows on it
