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