GRUB re-install error

[ronald]

I am trying to re-install GRUB, so my system will dual boot either Windows 8 or Kubuntu 12.04. I have rEFInd to override Windows and let me choose Kubuntu to boot up. I would prefer GRUB handle my bootup options. What does this error mean?

ron@ron-Lenovo-H430:~$ grub-install /dev/sda
/usr/sbin/grub-probe: error: cannot find a GRUB drive for /dev/sda2. Check your device.map.
/boot/efi doesn't look like an EFI partition.
rm: cannot remove `/boot/grub/acpi.mod': Permission denied

You really don't need GRUB if rEFInd is working for you and allows you to successfully boot both operating systems.

It's been a while since I used GRUB; isn't it necessary to put sudo in front of grub-install?

Yes.

Yes, I finally figured that out. Anything that needs root privileges must be preceded by "sudo" (no idea what that really stands for). I'm brand new to Linux, so little things like this I have no clue, and so they cause big headaches.
