I am dual booting Manjaro KDE and Windows for a while now, and it’s been working like a charm. But two days ago, when booting Manjaro, I encountered the error in the title,
Mount /sys/firmware/efi/efivars unknown filesystem type 'efivars'
So I did as suggested in older threads for the same error, and reinstalled Grub. It seemed to work for a while, but today when I tried to boot up Manjaro, the error returned. Again, I reinstalled Grub, but to no avail. I did notice, however, that sometimes when I attempt to boot, the error appears, but Manjaro does eventually boot. In other times, the terminal screen switches to high resolution and remains on the error, unresponsive.
Note: I am on the testing branch and run kernel 5.9. When attempting to run Manjaro with older kernels an error
failed to mount /boot/efi appears. Emergency mode however, is not usable, as the keyboard is unresponsive.
