@petergalgano et al, just about an hour ago I pushed an update based on a theory of the Windows 10 bcd not being compatible with the windows 7,8 and 8.1 OSs. The current inits in trunk will not attempt to replace the Windows 10 bcd as it has in the past. Please try updating and see if it helps. Also if you’re booting Windows 10 from UEFI, during up and down imaging please turn off secure boot. If the image is uploaded with secure boot on, it doesn’t matter anymore and will not work on any system but POSSIBLY the original uploading system and its not a strong possibly statement.
