Vostro 3700 will not boot -- need to restore from factory.wim

I cannot boot my pc and Repair Computer hangs. I see that the recovery ISO from Dell is not available for my computer. Thank you, Dell.

But I was able to get a copy of the factory.wim file off the Recovery Partition onto a USB stick before Final Failure occurred.

Two hours later after much searching I have no idea how to use this image to restore my machine to factory settings. I even made an ISO version of the file in case that would be needed to make installation media.
