Thanks again! Just to let you know, the dell certificate that is included in the download file didn't work. I tried searching for another dell certificate and it did activate the windows 7. I'm not sure if the certificate included in the download file that you gave me was a new one. I just wanted to know what is the proper certificate to use to activate it. Thanks!
Then you did not insert the correct bios for there was no warning messages to me.....your bios is so easy to modify and there should have never been a problem. Use the modified version of the link I just sent to you. I hope you can recover from this mess....let me know how it goes.
