After Reinstallation of media win-8 in my Laptop Wi Fi icon is showing Unavailable. how do I fix this problem thanks ravya123

Before that I made images of my XP and Vista partitions on my old disk which I installed on my new hard disk. (Unfortunately, I had forgotten to save the Dell recovery partition.)

Hi Everyone, Following a new HDD & install of the OS my Dell 1525 is not showing wifi or bluetooth and is not letting me connect via wireless. I have tried installing drivers but nothing. I can only connect via ethernet.
