My hdd started failing and I replaced it with a samsung evo 850 ssd. I did a clean install of windows 7 from a usb drive. Windows Vista was the original operating system. It won't activate and shows error code OxC004E003. Is it because the license is still active on my old HDD? If so how do i remove it..when I plug in my old HDD in an external enclosure it shows up in disk managment as unallocated space but not in devices or as a drive letter. I would also like to recover some documents if possible because i dont think the drive is completely failed yet, maybe just corrupt. Any help would be greatly appreciated. Thanks!
