to reinstall XP, use the boot up disk and on the boot screen that appears jus press ENTER>F8>ENTER and let the process finish...
(BTW - Not sure of the keys , better read instructions (easy) )
now the comp will reboot and then when it is rebootin, remove the cd or let it be and avoid the boot disk...
next a winXP style window appears , asks u a key after language...
enter it and then wait for the installation to complete...
thats it !
jus read the instructions on the screen and follow wht u like
P.S. > Why do u want to fomat ?
