    Windows 10 Cannot Boot - "/EFI/Microsoft/Boot/bootmgfw.efi not found"


    Hello Everyone,

    I have a Dell XPS 13 (9350) and was trying to update my Windows 10 install and it borked my dual-boot system. I was trying to install the Win10 Fall Update, and increased my GPT (EFI) partition to be able to install it, and now my computer will not boot:

    I found the following document on how to repair EFI partitions:

    However, when trying to repair the EFI partition, I get an access is denied when trying to run the "bootrec /fixboot" command.


    Can anyone help me out please ASAP? This is my computer for school! =(


    Thanks!

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

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

    Following commands will repair Master Boot Record (MBR), Boot Sector and BCD Store.


    Code:
    Bootrec /FixMbr
    
    Bootrec  /FixBoot
    
    Bootrec  /RebuildBcd
