Dell Vista PC missing "repair your computer" from "advanced boot options"

I am working on a Dell C521 vista system that the EU ran a recovery on the C: drive but ended up installing 2 copies of windows on the drive and somehow windows would flip between each install basically every time you would reboot the PC, they then deleted the C: drive and when they tried to access the "advanced boot options" menu after hitting F8 on startup the "repair your computer option was gone... this is how I received the PC.  The recovery partition looks to be unharmed on the D: drive  (hard to tell if any damage was done at this point until I can attempt a recovery).  I did some research on my own, trying to recreate the "repair your computer" and following the instruction to-a-T at this link http://www.svrops.com/svrops/articles/winvistare.htm and now that I have the repair your computer option back, I can choose it and proceed through the menu choosing my language, time and keyboard type, and then at the option where I can either "install now" or choose "repair your computer" if I choose repair your computer and choose my account, I try the "windows complete PC restore" but it tells me that "No valid backup locations could be found".... all this being said, I want to be able to access the partition on the D: drive so that I can get this computer back to the way it was when it was shipped from dell.... to me it seems like it is not searching from the D: drive or that I am still missing a few things to get the "repair your computer option working the way it did when dell had it setup... so this is where I am at.... worst case scenario, I have the dell vista DVD and I can install off of that, but the end user wants to be able to recover this system from the partition at need and if you install off the DVD you lose all the preinstalled crap that came with vista and it makes the recovery time 10X longer than if we were able to access the recovery partition... thank you and ask Q if you have them
