Hi, also trying to create a bootable USB device to install Windows 7 and getting the error that bootsect isn’t working even if you put it in the “%APPLOCALDATA%\Apps\Windows 7 USB DVD Download Tool” directory?

By the time you probably trying to create the USB on a computer installed with UEFI and here lies the problem, if you try to run bootsect from command-line, you’ll get the following error:

This tool can only be run on systems booted using a PC/AT BIOS. This system
was booted using EFI or some other firmware type.

Just use Rufus to create your USB boot device. This one is working on UEFI systems and is really fast with creating the USB boot devices.
