Ubuntu hp black screen + no action at all


I just bought a HP Zbook G3, I removed windows and install Ubuntu 20.04, then I installed additional drivers for Nvidia, once I rebooted it, it was ok, the second time I got a black screen from the beginning couldn’t do anything at all.

In fact, I reinstalled and now struggling to do the same for models and other softwares I was using.

@fipoucat How did you reinstall, for me I do not have the bios to choose usb or dvd to boot from !!!

I used a dvd in my case and it worked fine. I did not have the option reinstall but remove and install.
