or:check your os compatability is set. is there a partition drive? for what reason are you going to ahci. there is a setting somewhere thats not accepting it either the os. system permissions or you have a distorted file within your ahci settings that is making it not compatible for some reason. if you know what your doing search your regedit and system restore settings
