    UEFI Can't locate /efi/boot/BootX64.efi


    Hi everyone, Thanks for helping...

    I try to install a new PC (HP Pro Tower 290 G9 - RAM 8 GB) with Windows 10 64 bit... I created with Rufus from ISO file a bootable USB (GPT - UEFI - NTFS 4096 bytes as Cluster size).

    Rufus created 2 partitions : one with 4.3 GB of folders and files (like autorun.inf, bootmgr.inf, setup.exe) and one smaller containing one folder "EFI/boot/" containing 4 files .efi like BootX64.efi.

    When I start PC, I try F9 to select USB to boot from... I choose USB... And Boom error "Can't locate /efi/boot/BootX64.efi"

    Please help....If you have any idea, PLZ tell me...

    Thanks in advance

    Recreate the USB flash drive using the tool supplied by Microsoft:
    https://www.microsoft.com/en-us/soft...load/windows10

    Exactly what list of UEFI devices do you have to choose from? It may be counterintuitive but many times USB Hard Drive or USB HDD is the correct option.

    Also, are you plugging the flash drive into a black (USB 2.0) port or into a blue (USB 3.0) port? Some motherboards require a driver for the USB 3.0 ports to be active, so you could try plugging into a black USB 2.0 port.

    The UEFI devices listed are :
    - UEFI : my USB
    - UEFI OS
    - Debian

    The USB ports available of front are USB 3 because the sign is "SS".

    I would recommend using a USB port on the back, especially if black USB 2.0 ports are available on the back. Also, try the UEFI OS option.

    And I still recommend making the USB flash drive using Microsoft's own tool.

    The SOLUTION - Answer for Rufus/NTFS issues are STRANGEe -->> After USB creation rename the folder "EFI" end "EFI\BOOT" in in small letters!!!! -> "efi\boot"

    and also the bootx64.efi filename

    And if it it already was in small letters, rename the "efi" folder to something else and then back to "efi" and you can boot... But If you change it to small letters in the ISO, this isn't enough... You have to edit after creating the USB stick with RUFUS

    Please edit your profile with ALL your hardware specs. It will help us to help you
    System Specs - Fill in at Ten Forums

    Don't know why to use Rufus.
    I suggest you build the USB Win 10 22h2 installation drive using MCT

    If you already have a Win 10 installation iso:
    Open a CMD window as administrator and type:

    diskpart
    list disk (it will list all drives. Identify the USB drive number)
    select disk n (replace n by the USB drive number obtained with list disk)
    clean
    convert mbr
    create part primary
    select part 1
    format fs=fat32 quick
    assign
    active
    exit (to exit diskpart)

    On Win 10, mount the iso file and copy all files and folders to the USB drive.

    Windows can be installed in two ways: Legacy-MBR or UEFI-GPT
    To install as Legacy-MBR you must boot the installation drive as Legacy
    To install as UEFI-GPT you must boot the installation drive as UEFI.

    If you have a UEFI BIOS, you should install as UEFI-GPT
    Detach any other drives (SATA or Power cable) from the MB.

    During POST, press F12(?) to launch the boot menu. You will see two options for the USB drive. USB UEFI (Name) and USB (Name). Select USB UEFI (Name) if you want to install as UEFI-GPT or select USB (name) if you want to install as Legacy-MBR.
    Go to install and delete ALL partitions on the main drive till you have one and only one unallocated space and then proceed.
    If you don't want to use MS account, don't enable updates or connect to the internet during installation.

    Thanks for replying the basics here!

    But that doesn't solve the issue of using UEFI boot with NTFS on an usb-stick on "NEWER devices".

    UEFI & NTFS works on older computers with UEFI secure boot on for a Win PE usb-stick but not on newer ones.

    It gives this error what the thread is all about. I need NTFS to store larger captured Image files which exceeds 4gb...

    My custom WinPe builts boot on newer devices put to FAT32, but not NTFS. - Unless I rename the "EFI" directory as explained above after imaging the USB stick... and Then it works! No Error... But I cannot create an ISO file fixes this straight out from the ISO to USB-Stick procedure...

    Not clear to me if you disabled Secure Boot. The Rufus procedure requires that it be disabled.

    That restriction was removed ages ago.

    Even on the newer pc's I tested with disabling secure boot and the CA Database check. And also the Audit mode. No difference.

    On older devices with secure boot enabled it is is working with UEFI, only on newer models, mostly since 12th gen intel it gives this problem on NTFS partition, but like I said, If I image the USB stick, it isn't working, when I rename the Efi\Boot folder to still reflect the same name but with another mix of small/capital letters it is working. But I need to rename that folder, for example adding a folder isn't enough or renaming an other folder, it needs to be that one!
