    winload.exe missing or contains errors

    I have a Samsung Series 9 ultrabook with a preview copy of Windows 8 (and nothing else, no dual boot or anything). I downloaded (from MSDN) the full version of Windows 8 as an ISO and tried to upgrade to the full version. Now when I start the computer, I get a screen that says this:


    Your PC needs to be repaired

    The application or operating system couldn't be loaded because a required file is missing or contains errors.

    File: \$WINDOWS.~BT\Sources\Windows.NEW\WINDOWS\system32\winload.exe
    Error code: 0xc000000f

    You'll need to use the recovery tools on your installation media. If you don't have any installation media (like a disc or USB device), contact your system administrator or PC manufacturer.

    Press Enter to try again
    Press F8 for Startup Settings
    Press F9 to use a different operating system"

    Pressing Enter or F8 just brings up this screen again. Pressing F9 brings me to a command prompt window that says "A winpsehl.ini file is present, but no commands were successfully launched. This could be caused by incorrect formatting or an invalid executable name. Please consult the documentation for more information." Exiting this prompt returns me to the recovery screen.

    I have a bootable USB with the ISO on it, but inserting that and changing the boot order to have the USB highest doesn't change anything. Does anyone have any idea how to fix this?

    Yeah the problem is that your upgrading from a preview copy of windows and using an ISO not the upgrade tool that is set to be released in later in october when Win8 is officially released.

    Because of this you actually missed or corrupted some files in the upgrade.

    I think the easiest way for you to fix this would be to install a fresh copy of windows 7 (Don't worry about activation as it will only be on there for an hour) and then do a fresh upgrade from that.

    I actually had a similar problem when i did a fresh install and the above way solved it for me.

    Hope this helps

    P.s Have a look through this thread for how to do a clean install and what is recommended, i would list it but its already here.
