I have a Dell Inspiron M5010. Dual boot install completes easily and successfully every time. On start-up my machine hangs after log in. I receive no error messages, I get the default wallpaper and nothing more. I can occasionally see intermittent HDD activity making me think I'm not really hung, but I haven't ever successfully been able to login and I let it sit there for 30 minutes chugging away.
What can I do to identify the problem and solve this?
