Ever since Windows 8, making a Windows USB set up medium is less complicated than ever. Really easy, customers could make a Windows USB from the Linux terminal. Doing it is a very tedious course of, however so far as making Windows set up disks go, the terminal is the quickest and most fool-proof approach.
SPOILER ALERT: Scroll down and watch the video tutorial on the finish of this text.
The first step is to partition your USB flash drive. Windows USB installers must be in a particular format: Fat32 to be precise. This additionally signifies that by making the installer this fashion, you’ll be compelled to make use of UEFI mode. Not a fan of UEFI? Don’t comply with this information! Your USB drive ought to have at the very least 4GB house. Ideally, use one which had 8GB house.
Plug in your USB flash drive, then, in a terminal, run the record block command (lsblk). This command will reveal all block gadgets on the Linux PC. Pinpoint the /dev/ label of your USB flash drive. Consider of it’s dimension. It will allow you to decide what the drive is. Then, run the parted command:
Observe: on this instance, the USB flash drive’s /dev/ label is /dev/sdd. Yours might differ. Be sure you change it to what lsblk exhibits.
sudo parted /dev/sdd
Contained in the GNU Parted partition instrument, create a brand new partition desk. Because the Windows USB must be UEFI, this partition desk should be within the GPT format.
mklabel gpt
Reply sure to any questions GNU Parted asks concerning making the brand new partition desk. Then, create a brand new file system on the brand new partition desk, with:
mkpart main fat32 1MiB 100%
Then, exit GNU Parted with:
stop
Lastly, format the brand new partition with the mkfs command.
sudo mkfs.vfat -F32 /dev/sdd1
With the USB formatted, mount it to the PC. Don’t mount your USB flash drive throughout the file supervisor. As a substitute, make a brand new folder referred to as USB with the mkdir command.
mkdir ~/USB
sudo mount /dev/sdd1 ~/USB
Mounting The ISO file
The USB drive is within the correct format and able to maintain the Windows recordsdata. The subsequent step is to mount the Windows ISO as a loop machine to extract the recordsdata. It’s a bit tough however you may get the official Windows 10 ISO from Microsoft. Mounting as a loop machine is essential. Customers can’t simply right-click on an ISO and extract the info on Linux, as the info inside is hidden (form of).
Some file managers assist mounting disk pictures as a loop, although it’s iffy. The finest, most simple approach to entry this sort of knowledge is thru the terminal.
Step 1: make a folder for the Windows ISO to mount to, with the mkdir command.
mkdir ~/WindowsISO
Step 2: Mount the ISO, with the mount command.
sudo mount -o loop /dwelling/username/path/to/home windows/ISO/file.iso ~/WindowsISO
If the ISO file is mounted efficiently, you’ll see it present up when operating the lsblk command.
To unmount the Windows ISO file, use umount. Perceive that the ISO is not going to unmount until the contents of the ISO will not be in use. Don’t attempt to unmount it as recordsdata are copying.
sudo umount ~/WindowsISO
Making The USB
Each the ISO and USB drive are mounted to their respective areas. Now it’s time to make the set up medium. That is executed with the cp command. Nonetheless, earlier than recordsdata transfer, the terminal wants root entry. It is because the USB drive mounts as root, and a daily consumer can’t add new recordsdata and folders to ~/USB. Acquire a root shell with:
sudo -s
Then, copy all the contents of the ISO to the USB drive. Perceive that this course of will take a while. For finest outcomes, use a USB3 port, as they are typically sooner with file transfers.
cp -r /dwelling/username/WindowsISO/* /dwelling/username/USB
Copying is completed when you’re in a position to sort within the terminal window as soon as once more.
Observe: make sure you change “username” within the command to the identify of your consumer.
After the switch is full, unmount the USB flash drive from the ~/USB folder with the umount command.
sudo umount /dev/sdd1
If it refuses to unmount, and says “the device is busy”, attempt doing a power unmount, with:
sudo umount /dev/sdd1 -l
Fast Tip
Making Windows USB set up mediums throughout the terminal may be tedious. To save time sooner or later, think about using the Gnome Disks instrument to do a whole picture of your USB flash drive. Doing so will make a complete copy of the partition desk, and the recordsdata inside it. Then, when you must set up Windows, simply picture the backup on to the USB!
Remember the fact that the uncooked IMG backup of the USB drive would be the complete dimension of the flash drive. For instance: have a 32 GB flash drive with Windows 10 on it? Gnome Disk Utility may output a 32 GB backup file. For finest outcomes, use an 8 GB flash drive.

Conclusion
Windows has all the time been notoriously bothersome with their set up disks. Prior to now, simply making a USB installer on one thing apart from Linux seemed like a pipe dream, and customers have been compelled to make use of the “official USB tool”. Within the creation of UEFI, and extra common requirements, customers now could make a Microsoft-approved set up USB instantly from the Linux terminal!
