in that case you should be ok.
but i'm just being ultra-cautious.
my new-and-improved buy-one-get-one-free advice is to keep this 10gig partition for now, go ahead and install 7 into the other 100 gigs, and then if all is rosy, you can delete the dell recovery partition later, but only once you've established that all is groovy in the land of 7.
