One month ago I was trying to switch back to windows from Linux.

I did not what to do so i read some articles online and fdisk the partition on tty2. By mistake clear the partition.

Now when I boot I get error no partition:

Entering grub rescue

I did ls

I get (hd0) (fd0)

I don't get msdos1 or 2

What should I do

Also I can not boot into from CD or DVD.

Is my hard drive corrupted?
