I need some advice/help. My son has a Dell Inspiron that his dad ordered online from Dell. It came without the Windows Installation disc as most do these days. The other day, after it auto-downloaded Windows Updates, something became corrupted or is missing. It goes to a black screen with a message that says "windows boot configuration data file is missing required information". It wants him to insert his installation disc, which of course we don't have. His brother has an identical computer that they both got at the same time. Can I make a backup of the Windows OS from his computer and use it on the corrupted one? Is there anything I can do which will not lose all the files saved on the corrupted computer? Typical of a 20 year old, he did not back up any of his documents. His music can be re-synced from his iphone, but he has a lot of college papers on the laptop. Any help would be greatly appreciated.
