the entries have been modified since the bug occurred, because I had to install a system (otherwise the notebook would be useless). with "luck" I was able to install kubuntu, but in order to install I had to create 3 blank entries in EFI. it is very strange this bug, because it happens with or without the blank entries. my theory is that the installation of various distros made EFI "messy"
