Creating Windows 10 Bootable USB

What you need 

-Windows 10 install .iso or DVD 

-Freshly formatted USB flash drive with at least 5GB free space. 

-Technician PC - Windows PC that you'll use to format the USB flash drive 

 

 

      STEP 1 – Mount the ISO and Copy Windows Setup to the USB Flash Drive 

 

 

  1. On the technician PC copy everything except the Windows image file (d:\sources\install.wim) to the USB drive (either drag and drop, or use this command, where D: is the mounted ISO/Windows image file and E: is the USB flash drive.) 

 

robocopy D: E: /s /max:3800000000  

 

To circumvent the >4GB file size limitation of FAT32, split the Windows image file into smaller files using this command: 

 

STEP 2 - use DISM to split the image

 

Dism /Split-Image /ImageFile:D:\sources\install.wim /SWMFile:E:\sources\install.swm /FileSize:3800 

 

 
 

You now have a bootable Windows 10 USB thumb drive.
