I have a Acer Aspire R3. I was told that I need to do a restart. So I took all my important doc's and put them on my external hard drive and continued to perform the restart. No this was 6pm Sunday nite (9/24/17). It is now Tuesday (9/26/27) and it's stuck at 68% installing Windows, installing features and driver's. The screen go black Acer logo comes up and the same thing. Should it take this long to do a restart? How can I fix it? I really need it work for work
