After upgrading my Dell XPS 15 L502x, when i first logged in i noticed that icons and graphics were not good. So i went to device manager and there i read that ''intel basic display adapter was missing'' so i went for installation via device manager. Driver downloaded and installed and then a message popuped saying sterioscopic drivers from previous nvidia installation has some left over files, do you want to delete and i deleted then i was asked to restart my laptop.
After restart i am seeing this,which you can see in video link at bottom.
That white rectangle which says fast access was something like facial login. I never ever enabled it. I had it disabled in win 7. Don't know how it became a conflict with win 10.
My windows startup options with F8 key are also gone.
Please please help me out of this. What should i do?
