I read the tutorial on building a Windows EFI USB stick from the Windows ISO. I want to build an EFI/USB from an ISO of a bootable third party application, which is not designed to boot from UEFI. First, I went through the steps in Diskpart. Then, I copied the files from the third party ISO to the USB stick. Screenshot 34 shows the objects listed from the third party ISO. The second screenshot (35) shows what I have on my Win 8.1 ISO. I tried to just copy the efi folder and bootmgr files from the Win 8 ISO, but my Win 8 system (a VM) didn't like that at all. Thanks!

You need to be using a bootable software app, which uses WinRE4x64 for Windows 8/8.1, not a bootable software app, which is using WinRE1x32 for Windows XP.
