New Hard drive Not showing up on HP laptop

I just bought a new hard drive from best buy, its a western digital Blue 500gb hard drive, the old one was failing and causing windows to run slow so I bought this one to fix it. When I try to install the new OS into the blank hard disk it doesnt show up on the list, nothing does. Any tips?

Have you assigned a drive letter to the new hard drive ?

Go to diskmgmt.msc > right click at the drive > click Change drive letter and paths > then assign a drive letter > Add > OK

Does that work ?

how am I supposed to? there is no OS on it, also I put it into my desktop and formatted it with the drive management and assigned it drive "D" and then put it back in laptop and still doesnt show up. I even tried doing it through linux and fedora, still nothing.

Fixed it, apparently when I changed out the hard drive I loosened the other end that plugs into the laptop so it was half plugged in. Thanks for your help.

Oh. You are welcome.
Happy computing.
