Windows 10 ISO to FAT32 Flash Drive

9:08 am Uncategorized

Typically we can now use the Media Creation Tool to always have an up to date version of Windows 10 on a flash drive. Unfortunately the most up to date for the Media Creation Tool is a first half update (21H1) which only has 18 months of support. I always install the second half (20H2) as it will have 30 months of support for Education. I download the latest version of the ISO from our VLSC portal.

Prepare the Flash Drive

select disk X
create partition primary
select partition 1
format fs=fat32 quick label="Win10_20H2"
assign letter=w

Mount the ISO in Windows Explorer by double clicking the ISO file. Make note of the path. Example: E:\

robocopy e:\ w:\ /e

This will fail to copy the install.wim file as it is too large for a FAT32 volume. You must split it using:

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