Are you sure that it is actually installed twice? It just may be that the
Boot.ini File is fouled up. To check: Start/Run [or any other Command
Prompt]/type "msconfig' (without quote markers) and click "OK". This will
open the System Configuration Utility. Click the BOOT.INI Tab. If it shows
more than one operating system boot path (or even if it does not), click the
"Check All Boot Paths" box. If you have more than boot path and the result
shows one invalid, remove it and your problem should be solved.
If you have more than one OS installed, you should be faced with a choice
screen (which to boot from) each time you start. The same can happen if a
re-installation of Windows messed up the BOOT.INI file. Let us know what you
find.
