But you also need a system that can boot from usb and set the option in BIOS

I am using Win2flash to make pendrive installable. Win 2 Flash is free software and it support every windows edition and also other operating system like linux. I am try it on my netbook and install windows 7 succesfully. But it takes more time than DVD-Rom installation.

It looks like the problem is with you USB, if the USB is old enough then the installation will take time.
