I have 8.1 and 8.1 pro recovery media on USB, but haven't tried rolling back, as Win 10 is adequate, warts and all. If it's not booting, first ensure it's formatted with FAT32, and NOT NTFS.I can second that. If you Bing "Windows 10 on HP Stream 7," you will undoubtedly find links to how to do it. @horseybob, have you tried recovering to Win 8.1 from your Stream? I created a recovery disk, but I'm not having luck booting to it.
