whs-
1.) How do I know if I have a recovery partition? I did not set one up.
2.) MS told me with an OEM key that I cannot use ANY Win 7 installation disk to do a clean install but instead I need a specific installation disk that goes with the OEM product key. Do they know what they are talking about?
1.) In your list of programs, is there anything Dell branded? If yes, there will be a recovery option there usually.
2.) The beauty of Win7 is that any install DVD can be used, its the key thats the key. If this was Win7 from Dell, then you sould be able to purchase an OEM install media from Dell, or find a friend that has the proper Dell install media, and try your "valid key".
I wouldnt waste any more time, or effort, personalizing this PC as you will most likely have to perform a total reinstall either way you look at it! Also, I would let the ebay "retailer" be aware that you have contacted Microsoft on this several times, and that they are investigating the matter.
Also, if this lappy originally came with XP or Vista, if it was near end life with Vista, it may have come with an upgrade option to win7. I'd also visit
http://www.support.dell.com, plug in the Service Tag # on the Dell sticker on the bottom of the lappy and see if Win7 is listed as a possible OS for driver selection.
