I have just installed Manjaro kde on my hp elitebook 2560p. After rebooting, it shows error message:
Error: grub-file-filter not found.
Starting in rescue mode.
I searched for it on the Internet and answers say that it has to do something with installing bootloader in UEFI mode, mounting it on /boot/efi.
It doesn't show me /boot/efi flag which means I am running it in BIOS mode, I think.
I am complete noob and I had Linux Mint installed before. It was working fine.
