Any One Help me

yesterday i DECIDED to Partition my Hard Disk Drive. i faced the below Problem.

i booted computer from Cd room, then i typed Fdisk command,
after displaying partions, there were only two partiton (Primary 5% and Extend 95%) and there wasn't any non dos partiton, when i was deleting the Logical Dos drives, it replied there isn't any logical dos drive, then i went forward , i decided to delete Extend dos partitions, it replied when u have Logical Dos drives u can't delete Extend Dos Drive, even there isn't any logical and non dos partions. this was my headacheYour partitions were created by xp or w2k.My Partitions were created through Dos.Fazelqadir.......perhaps you could tell us exactly what it is your trying to do ......The operating system information would be of tremedous help to us .
The problem we have is.... while there are some very knowledgable people on this forum......I don't recall a single mind reader in the lot ........So we have to rely on you .
