    Did you try making the iso yourself ?

    And/or did you try replacing the contents of the successful 1909 iso with newer files?

    Hi there
    Used the MCT from Microsoft -- no UUPDUMP or anything. Same problem if I get the MCT to create a USB directly. I even tried burning to an old fashioned DVD -- same result.

    So the answer is no, you didn't try either of those things.

    I tried making ISO with Rufus, direct copy from Linux with dd and even burning via NERO and K3b. - Not throwing any more "Good money after bad" -- W2K19 Server LTSC installs just OK on the machine so I'll just run that !!!

    Restored image -- perfect

    Not sure why it's now called HYPER-V W2K19 server - there's no HYPER-V running on this machine -- at least not that I know about !!!

    I suppose there's always a "Rogue Machine" around somewhere.

    Perhaps something has changed in the bootinfo whichis causing a problem for your old machine.. You could try using the bootinfo from the working 1909 iso.

    I use USB flash drive partitioned to a small FAT32 partition for boot, and bigger NTFS partition for Windows Setup files. Works like a charm.

    I've made a tutorial for it on our sister site Windows Questions: WinPE - Create a custom Windows install USB | Windows Questions

    Hello @jimbo45,

    Just to add to @Kari's recommendation, there is also this . . .

     Ventoy

    About Ventoy:

    Ventoy is an open source tool to create a bootable USB drive for ISO/WIM/IMG/VHD(x)/EFI files.

    With Ventoy, you don't need to format the disk over and over, you just need to copy the ISO/WIM/IMG/VHD(x)/EFI files to the USB drive and boot them directly. You can copy many files at a time and Ventoy will give you a boot menu to select them.

    Most types of OS are supported [ Windows/WinPE/Linux/Unix/VMware/Xen... ], including, x86 Legacy BIOS, IA32 UEFI, x86_64 UEFI, ARM64 UEFI and MIPS64EL UEFI.

    Basically, depending on the size of the USB, you can have ALL your Bootable ISO's on the USB. Additionally, you can also have Portable Apps, Tools, Utilities, Folders, and Files, ALL on the Non-Bootable Partition of the USB.

    Also, @EdTittel, a Windows Insider MVP member, wrote this in his blog . . .

    I have created a USB using Ventoy and find it an invaluable resource. It is probably the best thing that has ever happened to Bootable Media!



    I hope this helps.

    Hi there

    How do I create the EFI bootable thing in the first place - this machine needs to boot EFI
    The default seems to create MBR mode --the stupid machine I'm on can't auto boot MBR/EFI and it's a horrendous hassle to get it to boot in MBR mode.


    update @Paul Black

    Got it -- bad case of "If all else fails RTFM !!!!!"

    This piece of hardware (the computer) is the ist to have a one way trip to the Tip once business gets going again properly and supplies from China / EU available here again !!!!

    I think its time to have a rest and watch some of the Euros with Cold Beer now

    I never use Rufus to build my USB Win 10 installation drive.

    To boot as UEFI and install as UEFI-GPT, on most computers, the boot loader must be on a FAT32 partition.
    To put all files and folders to a FAT32 partition you have a file size limit of 4G.
    Normally \Sources\install.esd (a high compressed install.wim) is smaller than 4G so you don't have any problem on copying to the Fat32 partition on the USB drive.
    If you download a iso that has the original install.wim (like from Heidoc) it will be bigger than 4G. The solution is to split Install.wim in smaller than 4G install.swm and install1.swm files. This can be done with dism.

    Assume you have a 8G USB drive and a Win10 iso file that has \sources\install.wim bigger than 4G.

    - Prepare the USB drive
    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)

    Create a Split.cmd
    - Open notepad and paste the commands below:
    Dism /Split-Image /ImageFile:install.wim /SWMFile:install.swm /FileSize:3600
    pause
    - Save as Split.cmd (not Split.cmd.txt)

    Split install.wim
    - Mount the Win10 iso file
    - Copy all files and folders to a blank/clean folder
    - place the Split.cmd on \sources folder and run it. It will create install.swm and install1.swm files.
    - delete \sources\install.wim and Split.cmd

    Copy all files and folders to the root of the USB drive.

    It will boot as Legacy or UEFI

    At one time - you could not use *.swm files with Setup.exe
    Although you could use the "Apply" method with *.swm files...
    I do not ever run Setup.exe anymore - I always Apply the Image... (It is a Much Faster Method of Setting up the OS) of course the Drive has already been pre-partitioned (which is easily done with a diskpart script)

    Kyhi, could you please explain?

    I have successfully used install.swm to clean install (booting from USB drive)
    I don't think I ever did an upgrade with install.swm as you can just mount the iso (with install.wim) and run setup.exe
