I am currently using Ubuntu 1604 as the OS on my laptop. It generally works well apart from one thing ... The FRACKING NVIDIA DRIVERS.
Nvidia you can go and die in a pit fire. At least 3 or 4 times in the last 6 months the driver update has stopped the system from booting. It gets to a black screen after the bios and never makes it to X-Window.
Since I have to google every time on how to fix this I am documenting it here. I will not be installing the Nvidia drivers again.
Press Esc or space after the bios to access the GRUB menu.
Navigate to > (Some Kernel) Recovery mode > Advanced Options for Ubuntu > root terminal
Mount drive as read-write
mount --options remount,rw /
Remove Nvidia Drivers
apt purge nvidia*
Hopefully Ubuntu will now boot into the X-Window normally.
