Right, so you download the
.ISO from Microsoft here.
Next you burn the image with a iso burner like Rufus.
Then after that you boot to the USB from the boot menu, typically by pressing
F11 key on boot. Be sure to boot the drive in UEFI mode. In the boot menu it will say
UEFI: flash drive. You do not want to install in legacy MBR mode.
If the drive fails to boot, make sure you disable
safe boot from the UEFI/BIOS.
If the drive still does not boot then try using a different USB as it could’ve gone bad.
