I figured out the root of my problem
I created the virtual disk at 64GB, however the target physical disk that I am deploying to only shows up as a little less than 60GB due to the 1,000 vs 1,024 MB discrepancy. My solution was to go back to my virtual machine, shrink the Windows partition slightly and recapture the image. After that the NUC was able to successfully download.
Thanks for the suggestions
