This USB flash drive can be used to boot any BIOS / MBR and UEFI / GPT computer. The difference between these two partitions is that on FAT32 partition, the Sources folder only contains one single file, the boot.wim file thatвЂ™s required for the USB to be bootable.

Now I had a USB flash drive to install Windows 10 which boots from a small FAT32 partition, then runs Windows Setup from the bigger NTFS partition: Then I simply copied all of the ISOвЂ™s content, including the complete Sources folder to the bigger NTFS partition on the USB drive. Now I created an empty folder on this FAT32 partition, labelling it Sources, and copied Sourcesoot.wim file from mounted ISO to this folder: I mounted the ISO, selected everything except the Sources folder, and copied these files and folders to the small FAT32 partition: Next, I created a 1 GB FAT32 partition and used the rest of USBвЂ™s capacity for an NTFS partition. The first step was to remove the existing single FAT32 partition that used the full 8 GB capacity of the USB. Here is how I created Windows 10 USB install media which boots from a small FAT32 partition, then gives control to aВ larger NTFS partition which contains the 4GB+ install.wim file. So, I had to create FAT32 media to do the job instead. Knowing his hardware, I suspected that at least on two computers he wants to reinstall he would not be able to boot from NTFS.

Then, he couldВ run Windows Setup from an NTFS partition. However, knowing my friend for whom I was making this installer USB is not familiar with manually deploying from a split WIM, it would be easier for me to make theВ ISO bootable from aВ FAT32 partition. OK, no problems, I thought, thinking that I would just split the WIM using DISM. For this multi edition ISO, the install.wim file is annoyingly 0.03 GB too big to fit in FAT32 formatted USB flash drive: I had the Consumer Editions ISO, downloaded from my Visual Studio subscription, and I wanted to use this specific ISO.

For those interested in how to do this very thing, IвЂ™ve written a tutorial on .Д®arly this morning I had to make Windows 10 version 1803 multi edition USB install media. Deploying my custom Windows image on that laptop from USB, I have been forced to split the 12 to 20 GB custom install.wim files that I create, so I can deploy them using DISM instead of running Windows Setup. I have an Asus laptop: itвЂ™s only a few years old, and it simply refuses to boot from NTFS.

ThatвЂ™s the realВ reason why theyВ can only boot from FAT32. But, unfortunately, there are still a number of computers where BIOS / UEFI lacks proper drivers.
