I've tried multiple options in the past without success ever since the one Windows file grew larger than 4GB. I recently stumbled across a simple method that may work. It requires using two USB sticks. Mount the Windows' .iso file by double-clicking it.
Erase one USB stick as MBR partition and FAT32 (msdos) and the other as MBR partition and exFAT.
Copy all the files from the mounted .iso file to the USB stick formatted with exFAT. You also want to copy all the files in the mounted .iso file, but exclude the "Source" folder. Once completed, eject both USB sticks (give them a minute before physically disconnecting them just to make sure the file buffers are flushed.
Connect the FAT32 USB stick to the computer and boot to the computer's boot picker menu. If you see an option to boot the USB stick with the Windows' installer, then plug in the second USB stick formatted as exFAT. Now select the Windows' installer boot option to see if it will proceed properly. Most computers need to boot from a FAT32 drive which is why two USB sticks is critical. The article I read mentioned that when the installer needs the items from the "Source" folder that the installer is able to locate them on the second USB stick formatted as exFAT. I guess you could try booting just the exFAT USB stick just in case the computer's firmware is able to boot from an exFAT drive.
I've never tried this option, but at least it doesn't require any third party software. I saw the Sysgeeker app before, but was hesitant to try or recommend it since there is no other mention of it anywhere.
