Well, I purchased iMac 20" very recently in March. It has 320 GB hard disk. I wish to have at least three partitions on it: 1. The existing one for Mac OS X without disturbing it. 2. For Win XP OS (NTFS) 3. For Data (NTFS). Presently I do not prefer to buy third party softwares. Has anybody got a proper solution? Already installed and removed Windows several times but could not get that extra NTFS partition to work. Please help.
