my laptop suffers with the intel-spi problem cant save bios settings, cant boot by any form.
at the time i only could boot to ubuntu (i had dual boot with win10) and i used one key recovery and i recovered windows but made boot impossible to ubuntu cause it erased grub so i deleted ubuntu partition. one day i wanted to install again ubuntu and i couldnt it was when i noticed that i couldnt made any changes in bios.
