I'm really new to Ubuntu and pretty scared with things right now. There were two partitions in the system partition 1 and partition 2 with ext4 format. Since I couldn't access them (I mean I couldn't create a folder or document or anything) I deleted these partitions and created new ones D and E with ntfs format. Now when I give

sufo fdisk-l

What I get is this

sujatha@sujatha-cellapp:~$ sudo fdisk -l
[sudo] password for sujatha: 

WARNING: GPT (GUID Partition Table) detected on '/dev/sda'! The util fdisk doesn't support GPT. Use GNU Parted.

sujatha@sujatha-cellapp:~$ 

But I had GParted create two partions D and E and I could see them then why it's not shown above..??

Also while starting system I could see a message showing like this

The disk drive for /partition 1 is not ready yet or not found
Continue to wait, or Press S to akip mounting or f for manual recovery

My GParted after partition looks like this after partition

The answer to your question is in the first output that fdisk produced:

WARNING: GPT (GUID Partition Table) detected on '/dev/sda'! The util fdisk doesn't support GPT. Use GNU Parted.

Your disk uses the GUID Partition Table (GPT), which the version of fdisk you're using doesn't support. You must use GParted, parted, gdisk, or some other GPT-aware tool to partition the disk, not fdisk. (The latest versions of fdisk do support GPT, but they don't yet ship with Ubuntu.)
