I was reviewing several old directories and I found different Windows recipes and scripts that I used often some time ago

Basically the following are the steps to create a Windows booteable disk from command line

What you will need: a flash drive (back in my time with 4GB was more than enough but I can see that current Windows 10 ISO is almost 6GB) and a Windows ISO file

cmd as Administrator

Open cmd.exe as Administrator. Windows menu, search for cmd right click > Run as administrator

cmd as administrator

or instead of right click: ctrl-shift-enter

Diskpart

Run Diskpart

diskpart

List disk will show all your disks. Select the flash drive unit, in my case ‘Disk 2’

All commands:

DISKPART

LIST DISK
SELECT DISK X
CLEAN
CREATE PARTITION PRIMARY
SELECT PARTITION 1
ACTIVE
FORMAT FS=NTFS
ASSIGN
EXIT

All steps are almost immediate except format that will surely take some minutes

Windows ISO

Remember that you can play with the developer tools, network conditions, user-agent to download the ISO file directly instead of the Windows 10 Upgrade tool

In recent versions of Windows mount an iso file is as easy as double click the file and it will appear as another unit. No mandatory need of tools like Virtual Clone Drive

mount iso

Copy files

You can simply select all files in File Explorer, copy and paste in the flash drive or among other options to copy files you can use the old xcopy

xcopy /s /r /h F: G:

or robocopy

robocopy /e F: G:

format

And that is all, you should be able to boot from this flashdrive and install Windows
