Guys I need help.
My desktop pc (HP Touchsmart 300) broke down and the technician told me to change the disk. He changed the hard drive and installed again Windows 7 Home Premium. A fiew days ago, I did a clean Windows install, by downloading the .iso file file from the web (Microsoft's webpage I think). I burned it to a disk and I started the installation. When i asked for a Serial Number, I wrote the key, who was behind the pc. The setup continued, but when I entered the Windows desktop for first time, a message poped up saying "This version of windows is not genique"-something like that. I re-entered the serial but again nothing! What is wrong? Did the hard drive change affected my windows activation?
