I am trying to boot into Ubuntu Studio 20.4.3. I downloaded the Live ISO and put it onto a 32 GB EMTEC USB Stick with Rufus (GPT/UEFI) under Windows. I also checked the ISO File hashsum.
I have a HP Pavilion Desktop PC TP01-2xxx and I want to install Ubuntu Studio (when booting works) on the 512 GB PCIe NVMe M.2 SSD.
So I boot from the stick and select "Try Ubuntu w/o Installing" - and here I also deleted "quiet" and "splash" and get this info:
Begin ... casper-premount ... done
done
stdin: Invalid argument
My screen looks like this:

Edit 1: When I use the MBR/BIOS partition scheme in Rufus, I get a more complex error, which really looks frightening:

Edit 2: As Windows is still running on the 512 GB PCIe NVMe M.2 SSD - I think I can rule out that this is a hardware issue.
Edit 3: I used another USB Stick (SanDisk 16GB) and it seems to boot a bit further, but still sticks at some point:

Edit 4: When I then boot a second time from the new stick, it sticks again at the original point. So I can't even reproduce the same errors.
Lately the error message looked like this:

Edit 5: The USB port that I use seems to have an effect too.
Any ideas?
