Need Help

Posted on Wednesday, December 14, 2016

I woke up this morning to find my main computer's ssd drive had died. I had Windows 7 professional upgrade on it that I had upgraded to windows 10 professional. I just went to reinstall Windows 7 and am told my serial number is invalid.  I don't have any windows 10 professional install files to use. Not sure what I should do at this point, any suggestions? Thanks!
