I recently installed Ubuntu 18.04 as dual boot next to Windows 10. I obviously got each system on its own partition and I got a swap partition as well.
The problem is that if i switch from Ubuntu to Windows, Windows doesn't start at first try. Grub2 shows Windows as bootable option and I land on the loading screen of Lenovo, but the window freezes after a while. After I "kill" my laptop with the power button, Windows starts without any problems. Ubuntu always starts without problems.
I hope any of you can help me because it's very annoying to always boot Windows twice.
