gparted is a very good program for formatting hdds which cannot be formatted by windows because the hdd has had linux or something else on it. it can fomrat into ntfs and fat32 and loads of others, i found it useful for formating my old seagate hdd.

and you need a iso burner so you can burn the file onto a CD-R and boot from it.
