Joe,
Why do you have two different installs of Windows 7?

The Master Boot Record is on whatever drive the first OS was installed on. Each of the installs, when booted to that particular, will most likely refer to THAT disk as the C drive. What I mean by that is this.

If you have one drive, with three partitions, and XP was loaded first, then the Master Boot Record is on the XP partition.

If you have three different physical drives, then whatever drive had the first OS installed on it will be the Master Boot Record.

ALL OF THIS assumes that you are doing a MultiBoot system, with a start up screen that asks what OS you want to boot into.

The next thing is, if you have three drives and three installs, when you boot into each one of them, the drive or partition that you are booting to will, or at least should be, the 'C drive.' So, technically, you'll have three C drives. What I would do is go into the Driver Properties and rename them, calling one XP Drive, Win 7 One, Win 7 Two, that way as they drive letters switch for each install, you'll know what is what.

I'm blessed watching God do what He does best. I've had a few rough years, and I'm still not back to where I want to be, but I'm on the way and things are looking far better now than what they were!
