Thank you I understand now.
So, would this be the RUU that everyone is talking about?
If so then I already put this in the root of my sd card. The name of it is like "Hboot Marvel" or something. It is what loaded the bootloader. So I don't think it's the RUU. I cannot find the RUU people are referring to. If it is, what am I doing wrong? It could be that my usb is not recognized by my computer, yet I can still access my sd card. And yes I have HTC Sync installed.
