Development Linux Ubuntu Windows

Windows 10 and Ubuntu freeze at the (blue window logo / purple screen) only if I restart from Ubuntu

Good evening, as always thank you for your time and help.

I have this annoying problem.


I decided to install Ubuntu 18.04 LTS in the secondary drive and Windows 10 is in the SSD.

The computer is an Alienware Area 51 R5 with the following specifications:

  • 220 [GB] NVMe (Windows 10 is here)
  • 2 [TB] (Ubuntu is here, in a partition of 1 [TB]. The other 1 [TB] remained untouched)
  • NVIDIA GeForce RTX 2080 Ti
  • Intel Core i7-9800X
  • RAM 32 [GB]

The installation was done following this guide:

Dual Boot Windows 10 and Linux Ubuntu on Separate Hard Drives


Everything seemed to run smoothly. This is not the first time I have done this.
However, I discovered that if I log into Ubuntu, then I press restart, at the GRUB menu, if I choose Windows 10, Windows freezes at the very moment the blue animation appears. If instead, I choose to turn off the computer (from Ubuntu), then turn it on again, I am able to enter Windows with no problem at all.

Another tests I did were the following:

  • If I log into Ubuntu, press restart, and then I choose to enter again to Ubuntu, it freezes.
  • If I log into Windows, press restart, I can enter to Windows or Ubuntu without any problem.

Ubuntu is up-to-date, same for Windows. The UEFI/BIOS was updated. And before attempting to install Ubuntu the following was set as follows:

  • Secure Boot is OFF
  • Fast Boot is OFF.
  • Hibernation is OFF.

Any ideas of what is going on and how could I solve it? I really appreciate any ideas. Thank you.

Update (30.11.2019)
I have tried the solution proposed by Ubuntu Freezing at Boot Time, which is essentially change to Nvidia proprietary drivers and edit GRUB. No luck.

I also tried one of the solutions proposed in Ubuntu 16.04 hangs on shutdown/restart which is adding ‘acpi = force’ in the corresponding line of the GRUB file. No luck.

Again any help is really appreciated.
