list disk
select disk 0
clean all
.

now after the whole hdd has been wiped out what should i enter to active/make C partition...?

DISKPART> convert mbr (or gpt)
DISKPART> create partition primary
DISKPART> select part 1
DISKPART> active (if this is the boot partition)
DISKPART> format fs=ntfs label=(name) quick
DISKPART> assign letter (letter)
DISKPART> list volume

I hope this helps :)

Use Diskpart to Create and Format Partitions

What are you trying to do, install Windows 7? If so, don't do anything, let the Windows 7 installer take care of creating the required partitions once you've done the clean.

I'm glad you got it sorted
