I've seen a lot of issues on the forums regarding this particular model.
Just got off tech support chat who confirmed there are no drivers for that model in the Boot Image creator. Hopefully it shouldn't be too much longer for their engineers to generate an update (sent them the AcronisInfo results).
Meanwhile, for those who want to run Windows 7 x64, search Dell's site for R230202. (of course, no need to install the entire package).
Hope that helps anyone.
Thanks.
