    Thanks so much for this! I was also stuck with the BSOD, and simply could not boot back into Win10 no matter what I tried. Using your technique above, I am now able to get back into Windows, however... I think I may have made a slight mistake following the directions. If I pull out my USB stick, Windows says it needs to shut down. Likewise, if I don't have the USB stick plugged in, it will not boot into Windows.

    Any idea what I did wrong in the above instructions?

    I had the same exact thing. I got it to work!! I've followed this guide and it worked! FIX: An operating system wasn't found on Windows 10 or Windows 8.1 (Solved) - wintips.org - Windows Tips & How-tos

    The reason why you have to have the usb is because the boot files are on the usb.

    So, the command should be: bcdboot c:\Windows /l en-us /s c: /f ALL

    Noticed the same letter used in the command? I had the exact same symptoms as both of you and I just booted into Windows like normally now!

    Hi fenix,
    I think I have the exact same problem: the brilliant solution documented above got me from not being able to boot my Windows 10 world yesterday to now again being able to always boot my Windows 10 (with everything as it should be as if booting and starting up just as it did before the problem began), BUT it will only do so if my System Recovery USB stick is in the USB drive. Were you able to solve this (i.e. get it so that the USB stick is no longer necessary)? I even thought that perhaps running Startup Repair from the System Recovery stick would maybe take care of the problem, but I can no longer convince System Recovery to get me to the troubleshooting screen to try that... instead it simply boots my computer and let's me get to my normal workspace.

    Im having a little problem, i followed the instructions and the "regular" start up did not work, it just send me to the same screen with the error code. but then i restarted the pc to enter the usb so i would be able to check what i did wrong and to my surprise, the pc went into windows!!!

    Ok, so the problem is that the pc is starting "properly" only if i boot the system with the usb were the Win 10 boot media is installed, if i take the usb out, the system will not boot. Also if i log in to my windows 10 and take the usb while using the pc, the system freezes and i have to restart.

    Can someone help me with this, i will really apreciate it.

    My first thought is that you do not have set your internal hard drive (with the installed OS) as the first boot device on the BIOS after the repair but your USB is still set as first boot.

    Thank you for your prompt reply and help!
    I have the problem whether the USB stick or the main hard drive (it's a Samsung SSD) is earlier than the other in the BIOS's Boot list, so I don't think that's it. Rather, I'm suspecting the problem is that my drive list in Disk Management does not show any drive whose Status is "Healthy (EFI System Partition)". I don't understand what that means, but I see my other computers have one. Here is a screen capture of my Disk Management screen:

    Maybe you can use this tutorial to restore/repair your missing EFI system partition. Restore/Repair Deleted EFI Boot Partition in Windows 10/8/7 – EaseUS

    Thank you lifetec, yes I am up for that!

    However (because I've never done something like this and don't want to screw up),
    I an unclear on this point: is my goal to convert that last drive list on my screen capture to go from being "Healthy (Recovery Partition)" to "Healthy (EFI System Partition)"? ...or is my goal to add another partition that will end up named "Healthy (EFI System Partition)"? Or something else?
    And if I am creating another partition: does it matter where in the partition order it is? And where will the space needed for it come from (i.e. do I have to first make another partition smaller in order so that there is some space to give to the new partition)?

    Thank you very much!

    If you have a GPT partitioning, the goal is to have at least the following partitions
    Healthy (Recovery Partition)
    Healthy (EFI System Partition)
    C:

    If you have a MBR partitioning, the goal is to have at least the following partitions
    Healthy (recovery)
    C: (System, Active, Primary partition)

    C: is the partition on which Windows is installed, the lettter may vary depending on what partition someone chooses to install, but this is the standard letter.

    If you don't see the EFI system partition, it usually means that you have MBR partitioning. But since the picture of your disk management is gone I can't confirm this, because there are many situations where the partitioning is just messed up.

    Thank you very much, Axe0. Your words are helping clarify this for me.

    I'm somewhat confident I had an EFI partition before things went wrong, but I am not sure. How can I determine if I am GPT or MBR?

    Here is the screen capture again of my Disk Management:
