Installing xp after installing vista

i have windows xp installed in c drive and vista installed on d drive. xp is running slow of lately due to many softwares installed on it. i want to make a clean reinstall of windows xp on drive c.

But since i have updated vista installed already on drive d, i dont want to re install vista again. how can i preserve vista bootloader and install xp at the same time..???

just install XP and then download vistabootpro and rebuild the vista boot loader.

^^exactly try that

thanx … will try that
