Hi,
Now it works, I forgot to change the IP address in storage management.
Thanks a lot.

@mimi1255 That only partially solves the problem. Now your network, as far as I can tell, is handing out boot files for UEFI machines. This will cause unexpected things whenever you get new systems in as most are now coming with default settings of UEFI enabled systems. While you are correct that you will need to turn off secure boot, this will not (at least I don’t think so) fix the problem you were seeing when you were UEFI booting the system.

@mimi1255 If your current issues are not related to the original problem in this thread, please start a new thread - and we will gladly help you there.
