I hace recently replaced my failed hdd in an old acer pc. I loaded the recovery software and thathseemed to go well, until the pc reboots. It reads "disc boot failure insert system disc and press enter". Despite the several attempts of reloading the system recovery software,and changing the boot order in bios i get the same result. Is it bad /old software, bad hdd? also i noticed that in bios the dvd/cd drive and hdd are labeled sata 1 and 2 respectively should the be or does that not matter? Thanks in advance.
