I was trying to rescue GRUB in Linux. I was able to login in the OS following this tutorial:
I have to upgrade GRUB to fix the problem. However, when I run
grub-install, I get an error:
$ grub-install /dev/sda grub-install: error: cannot find EFI directory.
My file system contains
sda6 for the EFI system, Linux swap, and Linux file system respectively.
I am not very experienced using mount or other commands.
