Getting the non system disk error. The HDD was pulled and placed in another identical laptop and it booted perfect. The boot order is set correctly but the HDD self test in the bios/tools screen is grayed out with the good drive in the system. I tryed resetting the bios by removing battery and cmos battery connection overnight. It did not help. I guessing its a motherboard to HDD connection issue. Since this is a laptop it probably means a new mother board is needed. Any thoughts or other suggestions as to what to try?
