In this case /dev/sdc6 is the / partitoin of the ionstaller that is being installed as an ext4 partition.

Title:
  grub fails to install when using entire disk with 3 disks with grub
  already on /dev/sdb

Status in grub2 package in Ubuntu:
  Incomplete

Bug description:
  To reproduce have sda as a 2tb hard disk with my main home partition and one other install on it of 14.10. Then I have my ssd /dev/sdb which is where the grun2 is installed and with the / partition and a manually install other partition of vivid on it that works. Then boot the lubuntu amd64 live iso for march 11th and tell it to use all of /dev/sdc a 250 gb hard disk I got from a lug member to test installs on. Grub will try to install to sda and fail and then bring up a menu to select which device to install to. grub2:
    Installed: (none)
    Candidate: 2.02~beta2-21
    Version table:
       2.02~beta2-21 0
          500 http://archive.ubuntu.com/ubuntu/ vivid/universe amd64 Packages
  Description:	Ubuntu Vivid Vervet (development branch)
  Release:	15.04

  I expected grub2 to install or on the second time allow installing to
  /dev/sdb instead it fails to install.
