Help with installation?

[Butfiend]

I am trying to install windows 7 from a USB flash drive. I select the USB for boot up. Then it takes to a black screen that says install proper boot device or press any button or something like that. Then I press any button and it shows the exact same message again. What does this mean? Is my windows 7 not going to install?

It means the USB device is not bootable, you most likely haven't prepared the device properly to make it bootable.
