choice if you are a two-3 system, first installed in 2000, after the installation of XP, the system will be activated when the natural system to start Select the screen, you can choose which system to start.
If you are a single system, but in 2000, I do not understand what you like the idea of what will optimize the Masters, “set to start with winxp”, not to mention It did not master the ability to optimize the use of a non-existent system to start is to think of yourself, you simply can not install XP system, how it might use it to start?

Just to see you add the question, if You get into the system, in 2000 to try to repair the installation CD-ROM, if you want to experience XP, do not want to give up in 2000, two-systems can be installed, the XP installation disc to the D in the future will be able to experience the XP.Reduction You do not know you have not installed? What is set to use the winxp start?
