I don't understand a lot of all this
No, I am not using any USB to boot. I just boot from sda4.
No, I am not using Chrome in anyway.
When I was trying to import bookmarks as html in Vivaldi, the Vivaldi blocked and I could not do anything else, then press the power botton. This was a few days ago.
But I had the problem with the hanging boot from beginning on, so when I was booting the corePlus from USB to do the installation.
Still don't know, what the first line means:
Wrong EFI loader signature
early console in extract kernel
input data 0x0071d0ae
input len 0x0049a1d1
output 0x00100000
output len 0x009be788
kernel total 0x00ad400
needet size 0x00ad400
Decompressing linux ... parsing elf ... no relocation needed ... done
Booting the kernel
This was the first what I saw, when I bootet the USB with corePlus, right after the menu where I can choose the boot. I had choose the first option from the list. Since then I have this issue. But I will now just delet the installation and do it again. First I will download the corePlus ISO again and write it to a USB. On my old Notebook I have done this with a tool in Q4OS that is named "mulitwriter". In the installation here on my new Notebook I have done ist with the tool from antiX. There I have the option to write it on USB "read only" or make the USB also writebl. What shall I take? Or shall I better do it with the terminal? If so, please let me know the codes I need to type.
