I know this thread doesn't fit this forum, but I'm desperate right now!! I'm trying to hook up a second internal hard drive, but when the computer is turned back on it says that no operating system can be found?? I'm pretty new at installing things but have seen a few videos and have some info, but have no clue what is wrong. When hooking up I'm using secondary connections on the ribbon to the mother board and the power supply. putting the new hd between the exsisting hd and the motherboard. Please help!! What's wrong??
