How do I remove hidden partition under Windows 7

Good afternoon guys.

I did a clean install of windows 7 ultimate over an existing Vista system on my Vaio FW11M laptop. however, windows7 has retained a hidden partition visible under the "manage" right-click option of my computer. Whenever i right click on it to delete it, I only get the option "Help". I cannot shrink/expand or delete it. I would like to delete it and would appreciate any advice on how to achieve this? Please see attached image.

Thanks in advance

Andy

Message to Bill2,

Thank you very, very much. Your solution worked like a dream. A totally unrelated question for you. Re your avatar. I use that very same theme from win 7. Extremely surreal, eh? However, I cannot find the artist name for it anywhere on google, as I would like to see which other realms his mind wanders into. Do you have any ideas? much appreciated.
