I've successfully removed and replaced my failed hdd with a new ssd but am unable to boot frim this drive because it lacks my operating system. What should i do next? Should I try contacting Toshiba? I can't do a factory reset for some reason “the hold 0 method doesn't work” and i dont have a OS disk. When turned on it simply says no bootable device go to bios ect. I was able to salvage the windows key from a program in Ubuntu but im not sure if its the right key since I am not used to using linux. I have another computer in home using Windows 10.
