How to fix Win 8.1 blackscreen and Ubuntu partition mount error ( Dualboot ):
Win 8.1 blackscreen :
This is a thoughtful issue for the users of Windows 8. Many have reported a strange error without any message prompts or problem definitions. On the word of protesters, Windows 8 bumps into a black screen after it boots, forcing them to restart. This could certainly be an issue of incompatible updates of Windows itself as well as device drivers, corrupted device drivers. The prescribed solution is to be initiated through safe mode, but as Windows 8 does not boot into safe mode in a usual way, you may need its installation disc.
Ubuntu partion error ( dualboot with Win 8.1 or 8) :
Windows 8, by default, hibernates instead of fully shutting down (read: to allow for fast boot). It's a pain but I believe if you tell windows to reboot into the special "Advanced Options" mode in the settings then you could potentially tell windows to shutdown fully. Check out this link to shut down your windows 8 pc fully (link to another question click here for their tutorial they found to disable fast boot).
