All I believe this is the sequence of events that got me here Alienware x51 R2 I "inherited" this from my son. I bought this for him as a christmas gift in 2014 and he's recently moved to a new box. I updated the bios through the Dell site and began receiving Activate Windows shortly thereafter. When I try to activate trough windows I receive an error code None of the resolutions to this problem on the net have helped. I have since tried to use the Dell OS recovery tool. When I run it, it recognizes my computer and the service tag, but says, "No OS image for this tag, though images exist for the product. I've scanned the answers in this community for this problem, but I haven't identified any that seem relevant. Can anyone suggest a path to green? Thanks, Der Duke
