Hi Tito, thank you for your reply. Unfortunately I am unsure what to do. I tried running NbDmiFit.bat in Dos but nothing happens. I tried running Bootx64.efi but the system always tells me that I should disable the UEFI Boot Option. But that is not possible. Is there some kind of tutorial or other more detailed information?
I did the following: Created a bootable USB-Stick with some HP Format Tool. Extracted NbDmiFit-1.19.rar to the stick and boot from the stick. When I try to start NbDmiFit.bat I get "Bad command or file name" I tried every HP...exe but only HPBFO052.exe works. What should I modify with this program? I am absolutely confused...
