problem installing grub to linux mint partition

[David H. Durgee]

I am encountering problems attempting to install grub on a linux mint 
18.3 (sylvia) partition on a multi-boot system.  When booting the live 
DVD and invoking its installer the partition is not listed as a target 
to install grub.

I opened a terminal window and attempted to manually install grub with 
the following results:


sudo grub-install -v /dev/sda15
grub-probe: error: failed to get canonical path of `aufs'.
grub-install.real (GRUB) 2.02~beta2-36ubuntu3.14+linuxmint1


Seeing the reference to grub-probe in the above error, I tried running 
that manually:


sudo grub-probe -v -d /dev/sda15
jfs



So grub-probe sees the partition, which is formatted with jfs, but 
grub-install.real isn't happy for some reason.

Where do I go from here?
