In summary:
Nothing except Lenovo Factory Recovery should be in D. We need to see a screenshot of its contents to help you Delete anything else and then you must stop writing to it if you want Recovery to work when needed. http://www.sevenforums.com/tutorials/9733-screenshots-files-upload-post-seven-forums.html
Once Recovery is cleaned out make your Recovery media to see if it still works and have a backup of the Factory Recovery. How do I recover my system using ThinkVantage Rescue and Recovery
If it won't generate Recovery media then it probably won't run, but you can try to queue it up from Win7 or from boot to test this following steps in tutorial above. If it won't run or boot then you can delete it as well as the OEM partition at the end of the HD which steps I gave you earlier.
If you are going to use Win7 backup, you must store it externally to an external or another HD, another PC on the network, or use another method such as http://www.sevenforums.com/backup-r...re-your-files-cloud-skydrive.html#post2269172. Only if the Recovery partition won't run will there be space there to make a partition to store your backup.
Ahhhh...another HD or externally. Well I don't have one hand
