You should have deleted all your partitions before installing Windows 7.  The Recovery is no longer usable since you installed Windows 7, so it can and should be deleted.
I have a Dell Studio 1537 with Vista 32 bits on the hard .I am trying to install Windows 7  64 bits as a clean installation and I noticed that there are three partitions on the hard drive :one with a small amount of space ; second space  with 14 GB of and about 9GB used  and is labeled as Recovery which I think is Drive D: in My Computer page;  third space ( much larger) which had Vista installed ,Drive C: I assumed. On this Drive C: I installed Windows 7 64 bit cleanly. Should I have format  the 14 GB space and install my Windows 7 on it?Am I not loosing this space unnecessarily?
