I remembered that I have a laptop lying around so I extracted the software from the DVD there. I have uploaded it for others here: Anyway, I noticed that your tool does not create a 'EFI Boot bootx64.efi' file which is required for Windows 7 to boot on a UEFI PC. It is a bit stupid that your software does not create this file, thus not making the installation bootable.

I have uploaded the file here: Extract it and put it on the USB flash drive at 'E: efi boot' or whatever drive letter your USB is mounted to. The below method is the correct way to prepare USB stick, the file I uploaded is the file described below. Preparing the USB Stick for UEFI Check if the file 'BOOTX64.EFI' via the path EFI BOOT is available on the stick.

If this is not the case, you can copy the file to the stick by using one of the two methods below: If access to the stick is via a UEFI-enabled computer with a Windows 7 (or higher) x64, the Bootloader can be copied and renamed to the stick. You can do this on the system partition under: C: Windows Boot EFI for the file bootmgfw.efi Copy it to the stick in the EFI BOOT folder and rename this file BOOTX64.EFI (notice the reverse order of efi and boot) The file bootmgfw.efi can also be extracted from a Windows 7 (or higher) x64 - DVD. It is located in the 2.7 GByte large archive Install.wim in the subdirectory sources. The archive can be extracted with an archiving program.

This file is located in the subdirectory '1' of the archive at 1 Windows Boot EFI. I also tried the ASRock software but it does not work, it complains that path of driver folder is not valid, but there is not even any option to select the location of USB 3 driver.

Allows Win7 to be installed even though it does not natively support xHCI.

Win7 will install fine after using the utility if installed in legacy mode. Modding the Win7 install media for UEFI or any other purpose is not the intent of the utility.
