    Windows 10 could not install revert back to Windows 7 failed


    Has anyone else experienced the following?

    My Windows 7 was updating to Windows 10. When it appeared to almost be done configuring a message appeared stating the Windows 10 could not be installed and it was restoring the previous version of Windows.

    Well that did not work. The pc will not boot up now. Instead I get: "Windows could not start because the following file is missing or corrupt: <windows root>\system32\hal.dll Please reinstall a copy of the above file"

    I hope I can add the file using the win7 dvd. I know I was getting low on hard drive space, but had cleared enough to have 4 gig or so free. It was either not mentioned anywhere or I missed how much hd space would be needed. Of course I am assuming that the install bombed due to this?
