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)

Was this bug automatically filed or did you do it manually? If it were automatically filed after the failure, it should have included log files. To investigate the issue we need a copy of /var/log/syslog.

I filed this manually. I have also get the same result trying an autoresize with free space left over after a manual partitioning that allowed me to install the bootloader to /dev/sdb. I have the /var/log attached of the failed autoresize into free space.

Can you run sudo grub-probe -v -d /dev/sdc6 and post the output? It seems grub can't figure out what /dev/sdc6 is.

Is sudo blkid but I ahve done other testcases since then and partitioning changes. I do not get this with manual partitioning and setting disc to /dev/sdb

Also I find that if you reinstall grub from the system that has the bootloader as documented in https://help.ubuntu.com/community/Grub2/Installing under post restoration commands.

I also get this on a latest trusty daily image for lubuntu 14.04.

sdc6 appears to be a swap partition, which grub should not care about. What configuration did you select in the partitioning screen? In particular, which partition is your root, and do you have a /boot?
