I just installed windows onto my system along side another drive which I have had a long time. The new drive (used) is much larger at 320GB. It worked ok until I tried to put in the windows updates. all the "critical" updates. Now the system won't start at all. Everytime start up repair attempts to fix it there is an error. I tried using system restore, and it could not successfully complete. Is there a way to repair this from my working hard drive? (the one I'm using right now) What has caused windows to not start?
