Discussion Overview

The discussion revolves around troubleshooting boot issues related to a Supermicro motherboard and Ubuntu installation. Participants explore how to set the boot priority to automatically use an SSD with Ubuntu, as well as address problems with a graphics card not displaying output during boot.

Discussion Character

  • Technical explanation
  • Debate/contested
  • Experimental/applied

Main Points Raised

  • One participant seeks to automate the boot process to always use the SSD with Ubuntu installed.
  • Another suggests accessing the BIOS setup utility to set the preferred boot device, noting common keys to enter BIOS.
  • A participant questions whether the user is encountering a BIOS screen or a boot loader menu, suggesting that if it’s a boot loader, configuration changes may be needed.
  • Concerns are raised about the correct boot order and its implications for booting Linux.
  • The original poster describes confusion about whether they are in BIOS or GRUB and shares images of the screens encountered during boot.
  • Participants discuss the potential issues with the graphics card setup, including the need for proper driver installation and configuration.
  • One participant notes that BIOS screens should display regardless of the graphics card setup, indicating a possible misconfiguration if no display is seen.
  • Another participant suggests checking if the motherboard has built-in graphics that may need to be disabled for the graphics card to function correctly.
  • Concerns about the keyboard not illuminating when the graphics card is connected are raised, with speculation that it may relate to motherboard settings.
  • A later reply indicates that the issue was resolved by setting jumpers and adjusting BIOS settings to prioritize offboard GPU units.

Areas of Agreement / Disagreement

Participants express various viewpoints on the troubleshooting steps, with some agreeing on the need to access BIOS settings while others explore different aspects of the graphics card issue. The discussion remains unresolved regarding the specific cause of the keyboard issue.

Contextual Notes

Participants mention potential dependencies on motherboard configurations and BIOS settings, as well as the need for specific jumper settings that may not be universally applicable.

Hi PF!

I just built a desktop and installed Ubuntu. The issue is, upon powering on the device I am taken to the BIOS display, where I have to choose how I want to boot up. I'd prefer the computer automatically always use the SSD, which has Ubuntu on it. Do you know how I can automate this?

I'm using a Supermicro motherboard, if that matters.

Your BIOS setup utility should have a way of setting which boot device you want it to pick to boot automatically. Most computers will display a message when they first start up that tells you to press a particular key (often F10 or Esc) to enter the BIOS setup utility.

Are you taken to the BIOS or to a boot loader menu, such as GNU GRUB?

If you are sent to a boot loader menu, you can change its configuration file to your liking. https://www.techbrown.com/change-grub-boot-order-timeout-ubuntu-16-04/, you have some instructions to do so to modify the one for a GNU GRUB boot loader.

PC probably won't boot if you don't have the right boot order so I am guessing this is a Linux boot loader.
 
Thanks for the replies everyone! I'm unsure if I'm taken to GRUB or BIOS, but here are two images: the image that says "please select boot device" occurs after I press F11. If I don't press anything I go to another screen automatically, where it looks for a bootable device, ultimately requiring me to turn off the machine.

All this to ask, how can I have the computer automatically log into ubuntu without seeing this?

If it matters, I want to do this because I have a graphics card I would like to use. When I plug it into the motherboard and connect the monitor the the graphics card, I get no response from the screen. From what people have said, it is likely that the graphics card will only work with the OS until I install the correct drivers (which cannot be installed unless the graphics card is plugged in and running).

Any help is greatly appreciated!

The screens in your images are BIOS screens.

On the first screen, it says "Press <DEL> to run Setup" just below supermicro.com (the right part of the first line of the message there), so pressing the Del key while you're at that screen should take you to the BIOS setup utility.

On the second screen, "Enter Setup" is one of the menu options, selecting that should also take you to the BIOS setup utility.

Not even the screens you showed images of? Those should come up regardless of the monitor/graphics card arrangement (the computer boots in a default graphics mode that should work with any monitor/graphics card combination). If you see nothing at all, it usually means something isn't hooked up right (wrong cable from monitor to graphics card?) or something isn't configured right on the card (jumper in wrong place, perhaps).

The screens you showed images of have nothing to do with your OS; they are straight from the BIOS. As above, they should display no matter what your monitor/graphics card arrangement is, since they don't require any graphics modes that are specific to particular cards.

The way I normally do this is to boot the computer from my installation medium for my OS (such as an installation CD/DVD for Ubuntu) with my desired monitor/graphics card combination already installed, and run the OS installation process with that monitor/card, so it installs the correct drivers.

Nope, when the graphics card is plugged into the motherboard and powered, I get no display. The fans attached to the graphics card spin, and a blue LED on the graphics card illuminates, signifying power, but no screen visualization. I noticed something else odd happens: I have a keyboard that illuminates, and when the graphics card is plugged in, the keyboard does not illuminate (the CPU is definitely on, as the same LED lights on the motherboard are on and the CPU fans are running) but when the graphics card is not plugged in, the keyboard illuminates. Any idea why, or if this is related?

Does your motherboard have built-in graphics? If so, you might need to set some jumpers or do some other configuration to disable the built-in graphics before it will work with a graphics card.

I think it does. I called tech support yesterday and switched the necessary prong cable. Just unsure if there was something more that perhaps one of you has experience with.

Any clue about the keyboard issue?

I suspect it's a side effect of whatever the motherboard is doing that makes it not work with the graphics card.

You were kind of right! The issue turned out to be manually setting the jumpers AND giving priority to offboard GPU units under "advanced" settings in the BIOS. After doing both of these, when I rebooted with GPU installed and connected to monitor, it worked.

Thanks for all your help everyone; I really appreciate it!
