You can't remove the C partition because it's your boot partition. If you want to completely reinstall Windows, boot from your XP CD, there is an option during setup to format your HDD. You can also check out a program called Super F Disk, which is used for formatting as well.
During the installation of windows xp sp2, i?m unable to delete the c partition (the only partition) because it contains downloaded update files needed for installation.
i want to format my hdd, and the c drive is the only partition. any thoughts?
ps: i'm now trying system recovery hoping that this will remove the updated install files, so that after that i can continue removing the c partition normally
