My computer is a Dell Inspiron 14R 3560. My HD has dual boot with a Linux Mint partition. It has also a Windows partition, but I can't configure UEFI... But it is another problem. The fact is that I see a error message every time I login Ubuntu or update/install programs. I suspect this problem was caused by a Linux Mint update. Maybe a Grub update. I am not sure. Any sugestions? Thanks in advance.
