I'm currently using windows 10 on my PC and, for the first time in my life, I decided to go for Ubuntu and uninstall win10. I just did create the bootable USB flash drive and then entered my BIOS to change the boot order. As soon as it restarted, now booting up from the flash drive, I got a black screen with 4 options:

  1. try Ubuntu
  2. install Ubuntu
  3. install Ubuntu OEM
  4. check disk for defects

That was the first thing that went differently from the guide on Ubuntu's official website. Anyhow, I went on install Ubuntu and then I had some errors until it finished up in a black screen with some errors on the text shown:

[11.175178] ACPI Error: [\_SB_.PCIO.GPPO.VGA_.AFN7] Namespace lookup failure,

Enter 'help' for a list of built-in commands.
(initramfs) Unable to find a medium containing a live file system

And in this screen, my keyboard isn't being detected so I'm unable to type 'help'. I tried to go for the first option (Try Ubuntu) and I had the same error. However, I'm pretty sure I have no more than 3 USB connected to my PC, including the boot drive.

I really don't have a clue about next steps I could take to make it work... Can someone help me?

Just in case I'll list my hardware:

  • CPU: Ryzen 3 2200G
  • MOBO: Asus Prime a320m-c
  • RAM: 8gb ddr4 ram 2133
  • VGA: GTX 1050ti
  • SSD: 240GB booting windows yet
  • HDD: 1TB Barracuda

I am not allowed to insert comments (yet) but these guys here

Error when installing: "unable to find a medium containing a live file system"

managed to get around the live file system thing by downgrading from USB3 to USB2.

That might be the cause of your woes.

Good luck!

  • I did try to downgrade it, and it didn't work... I even tried to change my usb stick and it didn't work as well... Thanks anyhow :) – Pedro Pomella Aug 10 '18 at 11:22
  • Bummer. I googled the motherboard and it does have a USB port that is USB3 as well as a USB port that is USB2. I assume you tried using both the ports. What a pain. NMaybe try a different distribution? Linux mint? – chai Aug 10 '18 at 23:14
  • tried Arch Linux and Manjaro :/ – Pedro Pomella Aug 10 '18 at 23:51
