Try to boot from different USB ports.

Make sure these BIOS settings are set as below:

* USB XHCI Hand-off is enabled
* CSM is disabled
* VT-d is disabled
* Super IO > Serial and Parallel Ports disabled
* DVMT PRe-Allocated is set to 64M
* Platform Power Management is disabled

Hi Namok88, first of all thank you for your patience.
I added the file to the Clover folder, checked the BIOS and it's all right.
Now the verbose proceeds more than before but stops in this row.

Try that one but also make sure to copy the nvram.plist next to the EFI folder (like in the picture)

I did everything you told me, unfortunately I have a Kernel Panic.

Why does it give me so many problems ? I don't think I have hardware problems, they are all compatible.

Make sure you are using USB 2.0 ports for your USB drive. This made a big difference for me. Still not installed but it got me to the installer.

Unfortunately still not work, I can't reach the installation screen. I have tried all USB ports. I tried to format the stick and put the last EFI (also file nvram.plist) but nothing. It always stops on the Kernel Panic.
I do not know what to do... Any idea?

You need to record the booting process and extract only the relevant part where the errors are and post the pictures here.
