I have been using Windows 7 without any major hiccups for about a month. I decided to "upgrade" my Kapersky internet security program to Norton 360 v. 3. That's when the well-documented problems started (e.g. unable to do an "unforced" shut down, unable to use Windows Update, etc.). So I rolled my installation to a prior system restore point and was met with a black screen with white mouse pointer. I can't seem to find the Windows recovery disc that is required to repair whatever was corrupted. Worst case scenario, I could borrow one from my brother, but that will take a week or so to obtain. Any suggestions to recover without use of the recovery disc or does anyone know where I can burn a recovery DVD as the beta download is now shut down? Thanks!
