I am experiencing weird behavior on a desktop PC with an ASUS X570-F ROG-strix gaming motherboard with the AMD Ryzen 9 3900X (which has no integrated graphics).

I've recently upgraded my hardware, and when I try to boot from an USB-stick which previously worked fine, I do get GRUB. When I then select the option "Try Ubuntu", it seems to crash; I get this (rather uninformative) screen:

enter image description here

I have already tried numerous solutions, but I am out of ideas. Thing I've tried:

  • Different USB sticks. Problem persists.
  • Different Ubuntu versions (Version 18.04.4 LTS, Version 19.10). Problem persists

I am using RUFUS to create a bootable .iso file on my USB-stick. When I try these USB-sticks in my laptop, I can use the option to Try Ubuntu. It then loads a live version of Ubuntu.

The specs of my new PC:

AMD Ryzen 9 3900X
Gigabyte NVIDIA 2070 RTX
32 GB of 3600 MHz G.Skill RAM
ASUS X570-F ROG-strix gaming motherboard
Samsung 970 Evo plus M.2 SSD 500 GB with windows installed
Samsung 860 Evo 500 GB with nothing on it (Ideally I want to install Ubuntu on this SSD).

I am out of ideas! Any help or tips would be greatly appreciated

    The NVIDIA video adapter has lost synchronization with the monitor. Adding the nomodeset parameter to GRUB is the next step towards a solution. You will need to edit the /boot/grub/grub.conf on the new USB flash drive using an editor on another PC.

    Thx! The problem seems to lie in that I did not have CSM-mode enabled on my mainboard. I just enabled it, and now i AM able to boot from the USB-stick. Strange.

    Cheered to early; now the Ubuntu loading screens shows up; However after that my screen turns off. I am able to boot into Ubuntu 19.1, but not into 18.04.4.

    Have you updated UEFI and SSD firmware to latest available? Even if new hardware there may be newer versions. Newest kernel is required. Asus ROG Strix B450 E motherboard UEFI update worked askubuntu.com/questions/1174679/…

  • I've updated my mainboard BIOS. Still the same result. I am able to select the options in GRUB, but after the typical ubuntu loading screen (google.com/…) my monitors say they have no signal and nothing happens.

Solved the problem! I tought it had something to do with my display driver. I have one monitor on a HDMI port, and the other on a DPI port on my GPU. When I unplugged one monitor, everything works fine and I am able to install Ubuntu like normal. Upgraded to the latest NVIDIA drivers, and everything is working fine even with two monitors.

Footnote: Explanation as to WHY this is happening would be great. I provided this answer so people know what to do when they have a similar problem. That being said, I will not accept it. Once somebody answers this question with a detailed explanation of what exactly is happening here, I will accept that answer.
