Wifi and software problems

[imadood12]

So one of my computer's hdd was failing so I took the hdd from my laptop and replaced it with that . I started it up. My main problem is that my laptop had a button for where wireless can turn on and off and when i took it out it was off so I cannot connect to my network , I'm pretty nooby on this type of stuff. Secondly it claims that my windows 7 is not genuine but in fact both computers were using genuine windows 7.. Did I do something wrong ? Thanks for readding!

This is what invalidated your windows. OEM versions are tied to the motherbd they are installed too and, as you see, windows periodically checks to make sure you haven't moved the drive.
