Guide: Windows 2016 Creating a Bootable USB when image size is greater then 4.7 Gb

[FrustratedAdam]

Hi Everyone, 

I ran into this issue and could not find clear documentation on what to do, here is the solution I eventually found, 

To create a UEFI Boot USB with a image that is too large for the required FAT32 Format.

1. Grab the ISO
2.Mount the ISO
3.Create a new folder, place all data from iso into it.
4. Find the Install.wim
5. Run this command chaging the paths as needed

Dism /Split-Image /ImageFile:C:\Users\--your user here--\Desktop\install.wim /SWMFile:C:\Users\--your user here--\Desktop\install.swm /FileSize:3800

6. Take the new SWM files and place them wherever you found the Install.wim.
7. Format USB with Disk Part to use FAT32 format
8. Place all files from created folder directly onto USB.

The USB should now boot from UEFI mode.

Hope this help whoever needs it!
