I tried to install Ubuntu 18.10 alongside with Win 10 using a USB. I disabled the "fast start". I kept "secure boot" enabled.
When I boot from USB, I first clicked "try Ubuntu". After the trial, I clicked the restart in Ubuntu, but my computer froze! I have to press the power button for 5s to shut down my laptop.
Then I start installing Ubuntu. At the screen "choose you time zone", I clicked "quit" as I want to install it at a later time. Then my computer froze. Again, power button to shut down.
I installed Ubuntu. I selected installing the third party software option as my laptop has Nvidia GPU with a 4K screen. In the end a message says "installation complete, please restart". I clicked "OK", and then froze and power button to force shut down!
I could see Ubuntu option as my first boot choice when I started the laptop. I entered Ubuntu and can open web browser and do other things. But, when I clicked shutdown or restart, it froze!
I selected to enter Win 10 once. Then I can never be back to Ubuntu. Each time I restart Win 10, it automatically goes to Win 10 without giving me the choice for Ubuntu as before.
Please help. Why does it freeze at so many occasions? Shall I disable "secure boot" or try Easy BCD software?
