Go to startup or system repair at boot, using your cd or hard drive as a boot option, and open a command prompt, type these in
While in cmd type:
Diskpart
List disk
Select disk (# you want to completely erase)
List partition
Select partition (partition # you want to wipe)
Clean

Now, all you need to do is boot using a windows 7 OS disk and install windows 7 on the disk you just cleaned (or erased) in diskpart

Make sure you aren't deleting the partition that is around 100MB in size, that is the partition with the windows boot files to allow it to boot.

Why not just boot off the Windows 7 DVD... to reinstall Windows... go to Advanced Options and DELETE the partition then reformat it and install? Seems much simpler.

SBM's solution is user friendly, try his way first. Although if your hard drive is corrupted as a format like RAW, you would need to use diskpart
