Was a Windows 7 Install DVD provided with its own Product Key?
If so, boot the Windows 7 Install DVD to CUstom Install, using Drive Options to delete all but the Recovery partition, then create and format your Install Partition to install upon.
It was not necessary to run Recovery to Vista to upgrade as you can clean install Windows 7. This is because MS insisted manufacturers provide a clean copy DVD of Windows 7 in order to partiticipate in the free Upgrade program.
If you have your Vista Recov disks made you can even delete the Recovery partition to use the space for your Windows 7 clean install.
