Well, he?s not being very informative by stating ?How??????. How do you format NTFS, is what the title is suggesting. Format NTFS doing what, what do you want to do; really?
If he wants to convert to FAT32 on drive C:, which Win2k resides on, then I?m sorry I misunderstood, but you?re going to have to reformat using Win2k. You need to do the Win2k installation process and delete the primary NTFS partition (C🙂 and format FAT/32. There is no way he can convert NTFS to FAT/32.
