Failed to install Ubuntu 18.04 or 20.04 alongside Windows
https://askubuntu.com/questions/1241708/failed-to-install-ubuntu-18-04-or-20-04-alongside-windows
I have tried installing Ubuntu about 10 times. It doesn't install. I first tried Ubuntu 18.04 and then Ubuntu 20.04. Both times I got the same screen telling me that the system has crashed. Here is how it went for 10 times. First I downloaded Ubuntu 18.04. Then I created a 50GB partition in D drive. Then I used balenaEtcher to make a 32GB bootable USB flash drive.
Then I restarted my HP Omen laptop, pressed F10, went to BIOS, changed the boot order to USB, found the Grub boot menu -- Try Ubuntu without installing. Then Ubuntu loads, I go for installation and I choose "Installation Alongside Windows". It goes to the end, asks for a restart and then it hangs. I get a black screen with a bunch of boot messages on it, and it gets stuck there.
The following are the screenshots of what I see on that screen.

Then after an hour it's still like this.
I left it for hours there and nothing more would happen. So I pressed down the power button for 5 seconds, shutdown my PC, and rebooted it. It still got stuck at the same black screen.
I tried doing this procedure for about 10 times with the same result.
This is the screen photo that I got.

Then I thought I'd redownload Ubuntu and try again, but it didn't work. I downloaded Ubuntu 20.04, but it also didn't work. The results are the same.
Just tell me is there any problem with my system, or is there any problem in my procedure? Just tell me what's wrong.
