Today I demonstrated the use of a tool which I use quite regularly to create bootable USB flash-drives from .ISO files, or existing installation media (i.e. CD/DVD disks used to install OSes) called Universal USB Installer, found on the pendirivelinux.com website. While it is primarily used for creating installation media for Linux or persistent Linux installations for various uses, the Universal USB installer has the added benefit of easily creating a bootable Hieren’s Boot cd flash drive, or other valuable utilities that require boot access. This software is capable of creating a windows vista/7 installation flash drive (but we will cover a better method in the future).
