I had a hand me down desktop given to us and it had no recovery disks as well and did not have the factory image of OS partitioned, it is an older Dell. I called Dell and explained my situation, even though it was out of warranty by quit a few years, they switched all the registered documents over to us as the new owner of the PC and sent out the OS DVD, apps DVD, a bonus DVD with some nice gadgets and the web site to down load drivers which I did and burned to DVD. When they arrived the next day because Dell sent it overnight on them, I reinstalled OS with the new recovery disc's. It might be worth a call to them. I spent a little over 30 minutes on the phone with Dell and now the wife is a happy camper. It can't hurt to try. good luck.
