    After latest Windows update, I can no longer boot up


    A month ago I did an upgrade install from Windows 7 to 10. Everything was working fine for a month. But a couple days ago, Windows installed an update and can no longer boot up.

    The first thing it does is an error screen with this message

    Code:
    The application or operating system couldn't be loaded because a required file is missing or contains errors.
    
    File:\WINDOWS\System32\winload.efi
    Error code:0xc000000e
    Which is weird because my C Drive is an MBR.

    If I press F1 to enter a recovery environment it gives me another error with this message

    Code:
    The Boot Configuration Data file doesn't contain valid information for an operating system.
    
    File:\BCD
    Error code: 0xc0000098
    So I created a new Windows 10 installation media flash drive and booted from that. I tried the startup repair, but that didn't work. Here's the log from that.

    I tried various tutorials to get the MCD to work, but none of them helped. Here is the command log from tonight, which includes results from rebuildbcd, bcdedit, sfc /scannow, and chkdsk results.

    And finally the DISM repair log file

    Execute Diskpart command and post a screenshot of the Command Prompt.

    Code:
    Diskpart 
    
    List disk 
    
    List Volume

    Your Windows 10 does not have System Reserved partition do you know why?

    I looked in my Macrium backups, and it seems like the one before I upgraded to W10 has one 223 GB partition, and a backup I made on the 15th after it started crashing has a 223 GB and a 547MB partition. So I'm guessing something must have happened between those two times.

    Rebuild System Partition

    This will need the assistant of Windows Installation Disc or similar bootable devices to help you enter into WinPE Command Prompt.

    1. Boot up your computer from the Windows Installer.

    2. At the command prompt, to create the boot configuration file on a system drive instead of the System Reserved partition, input bcdboot c:\windows /s c: and hit Enter. You’ll see a return message: Boot files successfully created.

    3. At the prompt, input bootrec /fixmbr and hit Enter.
    You need to make the partition Active, using Diskpart.

    5. To make partition Active, please enter the following commands successively.


    • diskpart
    • list disk
    • select disk n (where n is the disk number of the system drive)
    • list partition
    • select part 1
    • active (the correct message should be: DiskPart marked the current partition as active)
    • exit (leave diskpart)

    6. Now, input these two commands to rebuild BCD file.

    • bootrec /fixboot
    • bootrec /rebuildbcd

    7. When it asks to add installation to boot, print Y and hit Enter. Then, you may leave Command Prompt and start your computer now.

    When I get to that last part, it says
    Code:
    Scanning all disks for Windows installations.
    
    Please wait, since this may take a while...
    
    Successfully scanned Windows installations.
    Total identified Windows installations: 0
    The operation completed successfully.

    Also seems like it could be a problem that "BootDisk : No"

    Setting the disk as active should make it boot disk.

    Use the bootsect (bootsect.exe) utility to rebuild your computer’s boot sector code.

    Code:
    bootsect /nt60 sys
