I can't boot up Ubuntu from a USB 2.0 drive.

I burned Ubuntu 18.04, but I do not seem able to initialize it: I obtain (initramfs Unable to find a medium containing a live file system. I checked other posts, but I do not seem to be able to run Ubuntu. EDIT: nomodoset does not seem to work.

The errors shown at startup are here

Please help me out with this.

EDIT: Using Ubuntu 18.04, and nomodeset does not work. Using Ubuntu 19.10, with the safe graphics or nomodeset option does not work too.

EDIT 2: Problem solved. As pointed out in the comments, check the image with md5sum, and use a default tool, such as Ubuntu's Disk Creator to create the USB boot drive.

  • https://askubuntu.com/a/1217381/925971 enable nomodeset before booting – Gryu Mar 17 '20 at 22:22
  • @Gryu I've tried to do so, by adding nomodoset, after quiet splash, but it still doesn't work. I no longer get the Unable to find a medium containing a live file system, but I do get other errors. I've also tried the safe graphics option from the Ubuntu 19.10 image – raf Mar 18 '20 at 11:13

    SAFEST method probably would be: Take the disk out of the system. Buy a new disk. Install Ubuntu on that. Then run a recover program over the mounted partitions. – Rinzwind Mar 18 '20 at 12:43
  • You don't say that you've enabled in your BIOS your USB drive as the default boot disk. Have you done that? – Stephen Boston Mar 18 '20 at 12:54
  • Maybe there was a typing error. The boot option must be nomodeset with 2 o's and 2 e's, not as you wrote 3 o's and one e. – sudodus Mar 18 '20 at 13:01
  • Thank for all your inputs, I really appreciate that. Although the safest method would be taking the disk out, I have a laptop, and that process may be cumbersome, so I was trying to avoid that, if possible.

    Boot mode is UEFI, fast boot disabled, PXE Boot to LAN enabled, IPV4 PXE First disabled, USB drive before EFI PXE Network. Adding nomodeset right before the three dashes still yields the errors. I'll paste the errors in the post.

  • Please tell us about the computer: Brand name and model. I understand from the picture of the screen with 'nouveau' that there is a problem with the nvidia graphics. Maybe there is another problem too. So it is also good for us to know the version of your nvidia chip/card. It might help to try a newer version of Ubuntu that brings a newer version of the graphics driver, so try 19.10 or the developing version Focal Fossa, to be released in April as Ubuntu 20.04 LTS. – sudodus Mar 18 '20 at 15:17
  • Did you check with md5sum that the iso file was downloaded correctly? 2. Which tool did you use to create the USB boot drive? 3. Did you check from the boot menu, that all software on the USB boot drive is correctly copied? 4. And please tell us about the computer and graphics chip/card: Brand name and model ... otherwise we can only guess.

    @sudodus, thank you :) It was the way I was creating the USB boot drive. I used the default ubuntu Disk Creator, and it was fine. – raf Mar 19 '20 at 13:12
  • I'm glad that you solved the problem and thanks for sharing your solution :-) – sudodus Mar 19 '20 at 13:48
