I'm running Ubuntu and Windows 10 as a dual boot. When I select "Windows 10" from GRUB menu, it gets stuck at purple boot screen with diagonal broken lines, and won't boot further,reference. I worked without these problems since from many days, but I got this problem recently

  • Your Windows is not booting because your Windows has a problem. Your Windows problem is unrelated to the other OSes. You need to fix your Windows but that is off topic here. – user692175 Jan 9 '18 at 10:06
  • Can you boot Ubuntu successfully? If yes, could you please run sudo update-grub and try to boot Windows again? If that still doesn't work, could you please run Boot-Info and edit your question to include a link to its resulting info log? Thanks. – David Foerster Jan 9 '18 at 10:07

  1. Open the terminal and run this command: sudo fdisk -l

    Change the option in System Configuration to:
