Create LSTC USB

Question

Am I missing something? How do you create a bootable USB for 21H2 LTSC?? MediaCreation tool does not allow me for specify the ISO I want to use, and it also does not work if I overwrite the files with the LTSC ones. Rufus also fails me, by booting into some diag mode. Its a dell 7090.

Answer 1

You may install 21H2 LTSC from USB using Rufus on UEFI or BIOS devices

Answer 2

@Hebikuzure aka Murachi Akira - The Diskpart will not 'see' the USB. When I overwrite the files on a bootable usb already, it fails to start

@SSengupta - Rufus will creat the USB iso, but when it boots, it does not start the windows install, it starts some del diag tests

Answer 3

Since you can extract the wim file from the ISO image, you can create a USB media for installation by following the steps in the following article.
WinPE: Store or split images to deploy Windows using a single USB drive

Answer 4

I use Rufus to create a split USB flash disk to support UEFI boot. Small boot partition is FAT and the larger partition is NTFS.

1. I format the USB flash disk with RUFUS. My paper discusses using RUFUS to format a drive for WinPE, but the steps are the same for the LTSC ISO: https://www.annabooks.com/Articles/Articles_IoT10/Win10IoT-E-FFU-Capture-Restore%20Rev1.4.pdf
2. Next, I copy all the contents of the Windows 10 LTSC ISO to the NTFS partition.
