That's an extra entry in the hidden from view boot.ini file. Depending on how Windows and which edition of XP was on and is now on the boot.ini can edited to see that removed if no second OS is currently installed in a dual boot configuration.
First you would go to the menu bar in Windows Explorer or MyComputer when opened up to the tools>folder options>view tab in order to uncheck "hide protected system files" usually left hidden for novice users to avoid... ut ohs! GGrrr...! situations.
When browsing the root of C after you will note the yellow folder like file by that name and simply right on it for the properties in order to uncheck the read only box and click the apply button. Once that is done and the properties window is closed you can double click on it to see NotePad or another text editor WordPad open a new window up.
The default entries for a single copy of XP Pro should be like the image shown here if installed on the first partition of the first drive.
Once you uncheck the "read only" box in the right click properties you can easily double click on the boot.ini file itself to see it opened with Note Pad. After the bogus entry is removed with the cursor placed at the end of the line and the backspace used for that one line of text there choose the save as>all files not txt type from the dropdown options to see the new copy overwrite the current one. Then recheck the read only box after.
Whenever editing the existing one first make a copy to a folder in case you make a ...? Ut ohoo...! ! It's always a good idea to safeguard a correct copy anyways with the defaults in case any mistakes are made there.
If you lower the timeout too far while dual booting you can always overwrite it and later re-enter the added line for the second OS as well as saving a copy of the dual boot version too.

That's simply a tip there to see more replys when posting a question. You get to see more on one page rather then spit over several for basic ones while extended are generally seen when more involved problems arise.
If you eventually decide to upgrade to Vista there's also a great tool for editing the new type of boot loader seen there called EasyBCD. The information and latest version are seen at http://neosmart.net/dl.php?id=1 in case you want to save the link here for future reference.
