grub fails to install on selected device

[Peter Jansen]

I originally tried to install the 32-bit version and grub failed to install. I booted into another installed linux distribution, mounted the / partition and found only one directory, @. Inside of @ was what is normally in the / directory (all the main directories.) I used btrfs for the / and /opt directories. I moved all the files from /@ to / and was able to get the grub (from the other distribution) to find the ubuntu 17.04 install and add it. The install itself worked fine, just that grub wouldn't install, so I could only boot into it from another grub after fixing the root partition.

The bug basically was grub couldn't be installed on the chosen device. Choose any other device or partition to install grub, it still fails.
