Well, after a whole lot of screwing up, I ended up with a computer that has one copy of Windows and two copies to choose from upon boot. I suspect that means that there are two entries in the MBR. They're both from the same Windows CD, so I wouldn't know how to tell them apart when editing the MBR.
*One Windows installed, working properly
*Waiting 30 sec or having to wait for it to ask for your choice = pain
*Want to edited the MBR (or whatever needs to be) so that it just goes straight to the working Windows
*Don't have any tools except Hiram's Boot CD and have no idea how to work an MBR editor; I'd like to learn.
