uh what u have to do is get a windows 7 enterprise iso and then put it on ur flash drive! it shud be the only thing on there. then restart ur computer with the flash drive in! when it starts go to boot screen its the button F8 on my comp! then u choose boot from usb! make sure ur comp can boot from usb before u do the whole downloading process! or it will be waste of time! another way u can do it is by a DVD-RW same process. but gotta burn the iso to the disc rather than placing it in! any other questions feel free to ask me
