I am not at my home computer right now but I can describe what is happening. Initially, I had a hard drive with Vista installed on it. I then installed a second hard drive and installed Windows 7 on that drive. When I remove the drive with Vista on it, I get the bootmgr is missing error. With the Vista disk back in, and booted in 7, in disk manager I noticed the Vista disk has the System attribute and the 7 disk has the Boot attribute. If this isn't enough information, I'll post a screen shot later today when I get home.
