I am experiencing issues booting Ubuntu 22.04 LTS from a live USB. Despite following the usual procedures, the system fails to start. What steps can I take to troubleshoot and resolve this problem?

anonymous user

I’m really stuck with an issue I’m having booting Ubuntu 22.04 LTS from a live USB, and I’m hoping someone can help me figure this out. So, here’s the situation: I’ve followed the typical steps for creating a live USB—used Rufus on Windows to write the ISO to the USB, checked the integrity of the image, and even set the USB as the boot device in the BIOS. But for some reason, my computer just won’t boot from it.

When I start my machine, I keep getting the regular boot screen and then it goes straight to my existing operating system. I tried switching USB ports and even using a different USB stick, but no luck. I made sure to disable Secure Boot in BIOS, as I read that could be a potential issue, but it still won’t budge.

What’s frustrating is that I’ve done this a few times before without any problems. Is it possible that there’s an issue with how the USB drive was formatted before I wrote the ISO? I chose FAT32 as I’ve always done. Should I be using a different format? Also, I’ve heard about things like UEFI vs. Legacy boot modes—could that be part of the problem? I just don’t want to get caught up in a whole mess of settings that I don’t even fully understand.

If someone has faced something similar or has any pointers on what else I might try, I’d really appreciate it. Are there any specific diagnostic steps I should take? Should I create a bootable USB with different software or even a different version of Ubuntu to see if the issue lies there? Any insights into how to approach troubleshooting this would be super helpful. Thanks for any tips!

      Booting Issues with Ubuntu Live USB

      Sounds like a frustrating situation! Here are a few things you can check and try:

      1. USB Drive Formatting

      Even though FAT32 is commonly used, sometimes it can help to format the USB drive again. Try reformatting it with FAT32 using a tool like Rufus or Windows’ built-in format tool. Make sure to select MBR for partition scheme if you are using legacy boot mode.

      2. UEFI vs. Legacy Boot

      Check your BIOS settings. If your computer supports UEFI and it’s enabled, make sure the USB is also created for UEFI mode in Rufus. Alternatively, try to switch to Legacy Mode if you’re having problems with UEFI.

      3. Use Different Software

      If Rufus isn’t working for you, try using other software like Etcher or UNetbootin. Sometimes different software handles the bootable USB creation differently.

      4. Check the ISO File

      Make sure the Ubuntu ISO file isn’t corrupted. Check its checksum to confirm that it matches the official one listed on the Ubuntu downloads page.

      5. Test Different USB Ports

      Even though you’ve mentioned trying different USB ports, ensure you’re using USB 2.0 ports if possible. Some BIOS versions can be picky about which ports to boot from.

      6. Additional BIOS Settings

      In addition to disabling Secure Boot, make sure Fast Boot is disabled as well, since this can skip USB booting in some cases.

      7. Diagnostic Steps

      If you have access to another computer, try booting from your USB on that machine to see if the USB itself might be the problem.

      Hopefully, one of these suggestions will get you one step closer to booting that live USB. Good luck!

      It sounds like you’ve already taken many of the standard troubleshooting steps for booting from a live USB, but there are a few additional things you might want to consider. First, ensure that your BIOS settings are correctly configured for booting from the USB drive. When you’re in the BIOS, look for options regarding UEFI and Legacy (or CSM) boot modes. If your USB stick is set up for UEFI, but your BIOS is set to Legacy, you might encounter issues. Try switching between these modes to see if it resolves the issue. Furthermore, while FAT32 is generally the recommended format for USB drives, you may want to experiment with different partition schemes like GPT or MBR, as some systems might have specific requirements based on their firmware configuration.

      If none of these steps work, it could be worthwhile to use a different tool to create your live USB, such as Etcher or UNetbootin, as these can sometimes handle the nuances of the ISO more effectively than Rufus. You could also try downloading a fresh ISO of Ubuntu 22.04 LTS or even a different flavor, like Ubuntu MATE or Xubuntu, to rule out any corruption in the image you previously downloaded. Lastly, checking the USB drive for any potential hardware faults or using a different USB port on your machine might yield some results. As a diagnostic step, you can also run a live check on the USB through another computer to confirm that it is bootable elsewhere. Good luck with your troubleshooting!
