Bought a toshiba satellite C75D-B7215 that came with no discs whatsoever, and my hard drive crashed. I bought a new hard drive and was told that since my Windows was pre-installed (in my bios or motherboard or something) that all I would need to do was insert new hdd and it would automatically put my Windows back on it. That didn't work, still getting "no bootable device" message yet my hdd is listed now in BIOS. (Wasn't before, how I knew last hdd crashed) Anyone know what I would need to do to get this working? Step by steps are always helpful as I'm not exactly computer smart.. Thanks in advance.
