Live usb not bootable: “Couldn’t get size: 0x800000000000000e”

Hi guys,

After having build my new pc, I wanted to install ubuntu 18.04 LTS ont it.
So, I made a live usb with the Unetbootin tool.
When I am trying to boot on it, the screen freezes and I am getting this error message:
“Couldn’t get size: 0x800000000000000e”

I do precise that my pc contains the last Nvidia RTX 2080 super (released in July) and the amd Ryzen 3700x.
I have read that this message could come out from some issues with the graphics drivers so I tried to connect directly my screen to the motherboard HDMI output put the motherboard didn't send any signal to the screen, most probably because my graphic card was connected.
I also read that ryzens 3000 could generate some issues on booting with certains linux distros but that shouldn't concern ubuntu 18.04 LTS


Here is my build in details:
Motherboard: Asus x570 prime pro
Processor: Ryzen 3700x
Graphics card: Nvidia gigabytes rtx 2080 super
Ram: 16Go
Hard drive: Nvme samsung evo plus 500 Go

I would like to point out that this not my first installation, and that I never got such issues.

What would be the solution: updating the bios, using an other distrbs etc...?

I did a little research on this. The only help that I could find seems to be that there is a problem with Secure Boot enabled in the BIOS. You may want to disable that and give it another try.

Have you updated UEFI? New UEFI for support of Linux just released by vendors.


AMD UEFI/BIOS update for Ryzen 3000 series

ASUS ROG CROSSHAIR VIII HERO WiFi - update supports Ubuntu 19.04
MSI has also put out BIOS updates last week as a "beta" though without explicitly acknowledging the Linux fix.

Update the UEFI to the latest from the vendor.
if SecureBoot is off, you can safely ignore the warning.
