I have a Dell Inspiron 1525. When I attempt to use the Dell Recovery CD, I get Windows Setup booted, when it's expanding the files, at 81% it says this, "Windows cannot access the installation sources. Verify that the installation sources are accessible, and restart the installation." I've tried my Vista Business copy that I had as well and I'm getting the same error. What else can I try? If the DVD that came with the laptop isn't working, something physically must be wrong with the laptop? I can't get the thing to boot a DVD drive via USB, there's no option.
