I was on the web and then all of the sudden it showed I had no internet connectivity and about 20 seconds later I had no internet connections nearby and then showed the laptop symbol with an 'x' through it. I decide to restart my laptop and as it's trying to turn back on it says "The selected boot device failed. Press <Enter> to continue." I press enter and it shuts off. I tried hard resetting and it doesn't change anything. It takes me back to "The selected boot device failed..." endless cycle. Help.
