Comment 39 for bug 185878

Trying to install on my PC - that is already running Win-7. I added a 160 Gb drive to take Ubuntu ("Bionic Beaver) and elected to install the software here - /dev/sdd - and the boot partition is the existing 750 Gb boot drive for Windows 7 - /dev/sda - as I want a dual boot system for the time being at least.
Installer failed on the last step saying grub could not be installed to the / filesystem.
