I just built a new system with MSI 5700 Gaming Edge Wifi motherboard (with click bios), Ryzen 7 CPU and Radeon 5 GPU and Samsung M.2 SSD.
I made a bootable Ubuntu image with UNetbootin and confirmed that it works fine on my current computer. When I try to boot from it on the new system I initially get the error:
Couldn't get size: 0x800000000000000e MODSIGN: Couldn't get UEFI db list Couldn't get size: 0x800000000000000e
and then it gets stuck in the purple Ubuntu loading screen forever.
When I edit the GRUB entry and remove
quiet splash and add
nomodest I get the following scroll of messages (it goes way off the page but scrolls faster than I can read).
I'm assuming this is all caused by one problem (blocked by a certain hardware thing?) but I have no idea what it is or how to find out. I followed all the solutions I could find for the "UEFI db list" error and nothing helped. I have secure boot disabled (it was disabled by default). I tried switching between UEFI and CSM but that didn't change it.
What are the next steps I can take to diagnose this? Or does anyone have a guess what could be the issue?
