Can't find my bootable USB as an option in the UEFI options

Question

I'm using a Dell laptop with Ubuntu 16.04 LTS.

I tried to make a bootable USB after downloading the Windows 10 ISO file, but it doesn't appear as an option in the UEFI bootable screen.

I didn't use woeusb or any other program as I couldn't install them. I just made it using the Disks utility, then I formatted it as FAT32 then used **Restore Disk Image and restored the Windows ISO file. Is this a correct method of making a bootable USB?

Why could you not install woeusb or any other program? Do you lack superuser permissions (can you log in as root or run sudo or not)? Or is there some other problem, that prevents you from installing programs? — sudodus, Jan 10 '19 at 11:24

Cloning works with Ubuntu iso files but it does not work with Windows 10 iso files. You must use some other tool, for example mkusb (if you have an iso file downloaded from Microsoft), or woeusb (if you have a custom iso file where the file install.wim exceeds 4 GiB).

Install mkusb into your Ubuntu according to the following link,

help.ubuntu.com/community/mkusb

sudo add-apt-repository universe  # only for live standard Ubuntu

sudo add-apt-repository ppa:mkusb/ppa  # and press Enter
sudo apt-get update
sudo apt-get install mkusb mkusb-nox usb-pack-efi

Install woeusb into your Ubuntu and run it according to the following link,

WoeUSB Error Code 256 with NTFS formatted USB
