Thanks for the suggestion. Unfortunately, the Windows 10 Media downloader does not provide a hash. Both the Windows 11 and Windows 8.1 download sites provide the SHA256 hash for their respected .isos. I switched the NAS to truenas and was able to successfully use the Windows 10 .iso to install a VM. I do not know why it does not work on Unraid VM. Must be one of the settings. I've included a screen shot of the VM settings.
