I don’t know if this has been discussed before….so here goes. Win 7 primary snapshot plus 1 snapshot on C drive. One archived snapshot on a 2nd hdd. Update Win 7 to Win 8, install FDISR and make snapshot plus one archived snapshot on 2nd hdd. Using the Win 7 archived snapshot as the source, make a new snapshot on C drive. Restart and boot to the new snapshot of Windows 7. In Win 7, use the Win 8 archived snapshot as the source to make a new snapshot on C drive. Now you can boot back and forth between Win 7 and 8 as long as there’s no hardware change. Do you think this would work?
