Attempting to deploy WIM image over 4 GB from USB and having to create two drives per https://support.quest.com/kace-systems-deployment-appliance/kb/139312/fat32-formatted-usb-kbe-is-not-able-to-contain-images-or-files-larger-than-4gb
The USB KBE is Fat 32 UEFI and the image USB is NTFS. When the image deploys and reboots the UAC prompt appears on all tasks from that point. User must select “Yes” on the UAC prompt for each task to complete.
Go to: https://docs.microsoft.com/en-us/sysinternals/downloads/streams
1: Download the Streams file. Insert the USB drive with the NTFS image into your system.
2: Extract it (I suggest the root of C: for ease) You will find a 32 bit (streams.exe) and 64 bit (streams64.exe) file
3: Open Command prompt to the extracted directory ie: (C:\steams) and run the following command
4: Run 'streams64.exe -s -d F:' (this is assuming F: is the USB drive)
5: Allow it to finish.
Once finished restart the image. The image should deploy without the UAC prompts.
