No such partition grub rescue
The recovery partition is generally a seperate partition, and has to have a bootloader aware of it - installing linux often removes that bootloader, even if the partition is there. there IS, however a slightly roundabout way to get windows usable again - you will need a system rescue disk - which you can generate from another windows 7 system. that SHOULD restore the original bootloader.
You should then be able to make recovery disks from your windows install.
