text: What makes you think you have a second copy?  The prompt you get?  This means nothing.  It could be the same copy.\n\nfrom a command prompt, type:\nECHO %WINDIR%\n\nThat is your Windows directory. DO NOT DELETE IT.  Boot to the other install and do the same thing.  If both say C:&#92;WINDOWS then you DO NOT have two copies of windows, you just have a boot.ini file that lists Windows twice.\n\nIf you DO have two copies of Windows, then boot into the one you want and delete the folder of the other, as determined by that ECHO %WINDIR% command before.\n\nThen type NOTEPAD C:&#92;BOOT.INI\n\nLook at the lines there - it should look something like this:\n[boot loader]\ntimeout=30\ndefault=multi(0)disk(0)rdisk(0)partition(1)&#92;WINDOWS\n[operating systems]\nmulti(0)disk(0)rdisk(0)partition(1)&#92;WINDOWS="Microsoft Windows XP Professional" /noexecute=optin /fastdetect\nmulti(0)disk(0)rdisk(0)partition(1)&#92;WINXP="Microsoft Windows XP Professional" /noexecute=optin /fastdetect\n\nNote the name following ..(1)&#92; - WINDOWS is what you will probably see.  If there's another entry, then post it here and no one will see it because most people stop looking at these questions after they answer them.  So as an alterntive, use a site like www.experts-exchange.com or www.tek-tips.com to ask this question and people will actually have the opportunity to interact with you and help solve the problem.
