1809 1903 1909 iso will not work because UEFI requires FAT32 and the install.wim file is larger than 4 gigs. Windows 10 ISO contains INSTALL.WIM file that is big for FAT32 file system.  UEFI requires FAT32

• You have to have working win10 and Open an elevated command prompt to use DISM commands

• Run the following DISM command with the correct path to the install.wim and the desired file size in MB:

  dism /Split-Image /ImageFile:"c:\temp\install.wim /SWMFile:"c:\temp\install.swm" /FileSize:4000

• Now just replace the original install.wim with the created SWM files (install.swm, install2.swm, …)

Split a Windows image (.wim) file into a set of smaller (.swm) files.

Use this procedure when you're installing Windows from media that can't handle the Windows image file size, for example:

• DVDs (A standard single-sided DVD stores 4.7GB).  This is why DUAL LAYER DVD 8gigs is now REQUIRED for an install ISO.

• USB keys formatted as FAT32. FAT32 is required to boot many modern (UEFI-based) PCs, but has a maximum file size of 4GB.

• Due to the iso becoming larger than 4.7 gigs the flash drives MUST BE USB 2.0 and 16 gigs but no larger than 32 GIGS.  CANNOT BE EXFAT or NTFS must be FAT32.
