My intel cpu machine wont boot after the update.
But I get an animated logo for a bit then no boot device available.
Cant use USB to "upgrade" the installed version of windows because you must beable to boot into that version of windows for the upgrade to run
Safe mode does not work.
Can get to command prompt, and other repair options.
when restoring to restore point created by critical update (which I think fails because restore point does not go away) still cant boot {{ dont have patience to watch the system restore process}}
Any clues as to what to try with out a fresh new install ??
