OK, I just put the hard drive back in my dell computer after trying to build another computer with parts from Fry Electronics that didn't work out(another thread in its own). Booted the machine and it booted up just fine, like normal, but now in the lower right hand corner of the screen is a message that says "windows Vista Build 6000 This copy of windows is not genuine". I have no idea what MS is talking about on this one. I bought a retail upgrade version of Vista Home Premium, and have only installed it on this one computer. I did try to make a ghost image of the hard drive simply to have a back-up of my stuff in case something happened. I guess MS can come get me if they want to, I have a legal copy of Vista that is only installed on one machine. I give up. Sometimes I think we need to go back to a Big Chief tablet and a #2 yellow pencil!
