  1. Every single solution you provide is on the basis that you can successfully invoke the shift + F10 command. Unfortunately for me it doesn’t work, so still stuck in an irritating reboot loop.

    1. Same! So irritating… this is happening on a new Surface Laptop and unable to do the Shift + F10 no matter how I try…

  2. If shift + F10 does not work and you are using a laptop, make sure you also press the function button (FN) (to activate F1-F12).

    So press: shift + FN + F10 and it should work.

  3. The shift f10 worked until I got to this point:

    Computer Management (Local) > System Tools > Local Users and Groups > Users > Administrator.

    Mine does not say local users and groups. What do I do? I am concerned as I have a 13pg file typed on word. I hope I can retrieve the file at least.

    1. I’m stuck here too. Did you get an answer? Talking to Dwayne above.
      I also keep loosing my mouse and go through this convoluted effort just to get to the above step you mention.At this this point I JUST want to just boot and get my data and get a new computer. I can’t do elaborate fixes like re-install Windows. Mine also does not say local users and groups.

  4. Found a slightly different approach at https://answers.microsoft.com/en-us/windows/forum/windows_10-windows_install/windows-could-not-complete-the-installation-to/ef6119bb-5c9a-46c7-84a6-891fe2f69ba3?auth=1&rtAction=1512230719912 and replaced step 3 with my own version.

    Step 1: Download Bootable Windows ISO http://answers.microsoft.com/en-us/windows/wiki/windows_10-windows_install/how-to-download-official-windows-10-iso-files/35cde7ec-5b6f-481c-a02d-dadf465df326

    Step 2: Use Rufus to create a bootable copy: https://answers.microsoft.com/en-us/windows/wiki/windows_10-windows_install/how-to-prepare-bootable-install-media-for-windows/442447c3-0826-4473-a5b7-36568d20ef9d

    Step 3:
    – Allow computer to boot to error dialog box.
    – Insert Bootable USB produced in step 2.
    – Use Shift-F10 to bring up command prompt
    – Bootable USB should be available as disk D:, but you may need to experiment to find the drive letter.
    – Run the following commands in command prompt
         – D:\setup.exe (Replace with correct drive letter)
    – This will start the setup process again from within the currently running system and perform the upgrade process properly.
