I can not prepare a USB flash drive - it does not boot with the installation. The very process of preparation of the stick is fine, it is written that you're done. In the preparation of the stick with WinToFlash and copying it received in the distribution of Windows 7 Toolkit 1.3.0.98 and it works. Possible reasons: 1. W7T incorrectly creates a bootable partition on the USB drive 2. W7T replace third-party boot loader
