First and foremost, welcome to Rootzwiki, we do not flame here. I'm assuming you come from a DX with CM7 since you wiped /system. That is never required unless specifically stated. So this probably is where you borked your phone. The drivers it should be installing are Motorola ADB Interface when connecting to Fastboot. Do you have a friend with a windows 7 machine? Or with a linux box? You might have better luck on a different system. If you can't find a way to connect your phone to a computer to Fastboot it you might be stuck I'm afraid to say.
