how to delete my partition table?

hello. after using norton ghost restoring my drive C, it left without restoring back the “temp” partition and messed up the partition table.

now im having this partition table problem, so im planning to destroy the partition table then repartitioning it and reinstalling windows.

for which even from start it seems helpless with fdisk or with Parition magic. both of them would say it is impossible to write to disk, i have even used an utility called “Super Fdisk”. which seems hopeless too, it says “error writing to disk”.

what can i do to help in this situation?
