my current issue is that every time I boot into ubuntu, it shuts down immediately and restarts again itself. It goes into a loop.

I am trying to boot into Ubuntu 20.04. (I use the safe graphics install to install Ubuntu 20.04 to my Samsung 980 pro nvm SSD card)

The only interface that the computer does not shut down is the GRUB.

Can anyone help me troubleshoot this strange thing?

The following are the only things that are set up in my computer build right now:

  • Motherboard: Z590 MSI PRO WIFI

  • CPU: i9-10850k and a CPU fan

  • RAM: one 16 gb 3600MHZ, 18

  • M2: Samsung 980 Pro NVMe

  • power supply: EVGA 700 GD, 80+ GOLD 700W

@ChanganAuto and @oldfred Thank you for the suggestions.

Currently, What I have tried which can log into the OS and even the user interface is edit the Ubuntu option in GRUB. However, only before 5 minutes the computer shuts down itself.

Specifically, I added "$vt_handoff nomodeset". When loading, I found that it keeps saying that Bluetooth hc10: reading intel version information failed (-22)

I solved the issue.

It seems that there are extra steps that finally make my new computer boot successfully. Here is how I solved this issue completely (I hope).

  1. buy a new power supply. I bet the original one is defective which may explain it shuts down immediately after post/grub every time.

  2. In the Grub mode, I modified the argument by adding nomodeset at the end of the lien of linux argument.

One may search for nomodeset via google to see related information. As a matter of fact, the safe graphic mode for installation includes nomodeset.

See reference: Black screen after installation of Ubuntu 18.04

  1. After I successfully installed (using safe graphic mode) and use nomodeset argument when boot in, Wifi and Bluetooth cannot use. And I donot want to use nomodeset every time. Fortunately I have Ethernet cable. I follow this link https://forums.linuxmint.com/viewtopic.php?t=346412 and install linux-oem-20.04b via sudo apt install linux-oem-20.04b in the terminal.

From install to complete:

  1. in Grub mode use safe graphic mode to install.

  2. When boot into the installed Ubuntu, add nomodeset.

  3. Open terminal and enter sudo apt install linux-oem-20.04b.
