Install crashed: Unable to install bootloader at specified location

[j1n3l0]

Tried to install over existing ubuntu 17.04 gnome installation. Worked fine up to the point I was presented with the error: "Unable to install bootloader at specified location". I was also unable to cancel the installation even though it was presented as an option.

You tried to install grub to /dev/dm-0, which is an LVM logical volume. It must be installed to a hard disk, such as /dev/sda.
