    Dual boot Windows 10 won't boot up - error oxc 0000428


    My Windows 10 will no longer boot up. I get an error oxc 0000428 saying it cannot verify the digital signature windows/system32/windows.exe.

    My Sony Vaio laptop has dual boot, Windows 7 32 bit and Windows 10 (upgraded from Windows 7 64-bit). It is the latter which won't boot.

    The problem occurred after I probably pressed the incorrect function key because I was trying to get to the BIOS to stop the laptop booting up from USB drives.

    I've seen you should be able to press F8 to get the repair screen but I simply get the error screen and I go round circles when it asks which OS I want to boot. The Windows 7 (recovered), the 32-bit one works, but the one listed as Windows 7 simply goes to the error screen and I can only get from that back to the boot list screen.

    How to I resurrect my Windows 10?

    Help much appreciated.

    You'll need the 10 installation media to possibly use it's recovery tools
    I doubt the win-7 tools would work properly since 10 acts like an alpha and hijacks the boot loader...

    Looks like malware infection there is no such file as windows.exe you will have to delete this file.

    Please boot your computer with Windows Setup Media and from Windows Recovery Environment start the Command Prompt.

    Please type below command into Command Prompt and press Enter key.

    Following command will delete windows/system32/windows.exe file.

    Del  /f   /a  /q   D:\windows\system32\windows.exe

    Please replace partition letter D: with Windows installed partition letter. When computer boots into Windows Recovery Environment (WinRE) environment the drive letter assign to Windows partition may not be C: drive letter because Windows 7, 8 , 8.1 and 10 creates a separate system partition when it's installed from scratch. The system partition contains boot files WinRE assigns the system partition the C: drive letter and the Windows installed partition will be assign any other drive letter usually D: drive letter is assign to Windows installed partition. The Bcdedit /enum | find "osdevice" command can be use to find out the drive letter of the Windows installed partition the output of the Bcdedit command is similar to this osdevice partition=D:. The drive letter after partition= is the drive letter of the Windows partition.
