# Create bootable USB drive for Windows 8 clean install on UEFI

How do you burn a Windows 8.x ISO image to a USB drive such that it can be clean installed on a PC with UEFI enabled? I tried using the Windows 7 USB/DVD download tool, but the target PC didn't see the USB drive as a boot option.

This question is similar to No discs found when trying to install Windows 8 with UEFI, but more general. The related question is targeted to a particular laptop and storage technology. –  Edward Brey Mar 14 '14 at 2:12

1. Open an admin command prompt, and enter the following:

diskpart
list disk
select disk x (where x is the number of the USB drive from "list disks")
clean
create partition primary
format fs=fat32 quick
active
assign
exit

2. Mount the ISO image (in running Windows 8, just double click in Windows Explorer).

3. Copy all files and folders from the mounted ISO drive to the USB drive. You can use Windows Explorer, or xcopy x:\* y:\ /s /e, replacing x: with the ISO drive and y: with the USB drive.
