currently i try to upgrade my Window XP Home Edition to Window XP Professional Service Pack 2 in the C: drive which is only 5 Gb while my other partition (D: drive) is of 15 Gb. Since the size of my C: drive is not sufficient to support so-many softwares available nowadays, i decide to delete the D: drive partition so as to re-create the hard disk into 2 partitions, with 10 Gb each. To my dismay, both partitions (C: and D: drive) cannot be deleted during the hard disk formatting. Hereby I would like to seek some advices from the members of this forum towards this matter. Your advice is highly appreciated. Thank you.
