I have xp and want to change back to 2000. My pc will
not do this. help

.

what you can do is that when you restart your computer go
to the bios by pressing del. then you should boot from
your winXP CD. After doing that just exit bios and save
the settings. when the computer starts it will ask u
whether to install uninstall or modify. just do the
uninstallatio. By this way u can uninstall winXP and in
the same way install win2000 by a boot up CD.
