I have a Gateway NV52L15u that the hard drive (500gb Hitachi) went out and I am trying to replace it. It was running Windows 8. I have a spare Dell laptop with same HD (but 250gb) that was running Windows Vista that I put in the Gateway and everything went in nicely, but when I power up the Gateway a blue box comes up and says "No Bootable Device, Hit Any Key". When I hit any key it takes me to the Boot Manager screen for Boot Options and directs me to change options to boot, but there is nothing showing to boot from. Can I make this HD work or not? What do I need to do? I am not total good with computers, but if I have step by step directions I can do it. Can someone help me PLEASE?
Thanks in Advance
