FYI: The dpkg configuration setting for all packages are in:
> /var/cache/debconf/config.dat
My setting for the GRUB devices were stored around:
> Name: grub-pc/install_devices

Found the issue. Do the following:
> sudo debconf-show grub-pc
> sudo dpkg-reconfigure grub-pc
The last screen sets the default GRUB device(s).

Title:
So, the undocumented "GRUB_DEVICE" may be the answer. I could only find
it in a Gentoo post:
GRUB_DEVICE (detected) Device node for the volume containing the root
filesystem. Set this to override the grub2-mkconfig command's root
device auto-detection. For example, GRUB_DEVICE=/dev/ram0 will

This error crops up when a new kernel is installed during an
update/upgrade. The update-grub command is called which in turn may
call grub-install. It seems to always default to /dev/sda instead of

you are booting from a SATA drive and have 2 IDE drives, you will always
get /dev/sda

Hi, Bin Li. Thanks for your answer.
Do you mean it's not possible for ubiquity to identify by itself the
first disk in boot order without touching manually advanced partitioning

default?

It depend on the boot sequence of your BIOS. If the SSD is the first
one, and you install the grub on HDD, you can't boot up into HDD. You
need change the boot order. Or enter the boot menu with F12, after that
select HDD to boot.
