Software RAID 1 - Grub cannot install to the MBR of either drive #4

I am trying to install this with the current bootable usb ISO on a dual drive Windows / Atom terastation (WS5200DWR2). the installer fails at the bootloader install part, as do repeated attempts or go-overs.

Does anyone have any advice?

Good to hear from you!

I’m guessing you need to add a “BIOS boot partition” for grub to install for your configuration. It allows grub to install additional code needs for raid/etc that don't fit in the mbr.

I .... don’t see that I’ve documented that anywhere which seems like an oversight. I’m guessing the Linux-based Buffalo firmware must come with these partitions which is probably why most people haven’t run into it before now.

I believe you can create one from the partitioning menu but haven’t looked at it in a while. I can boot up the installer on a device when I’m online tomorrow and take a look if needed.

In the meantime here is what my partition table looks like for my ts5000:

Number  Start (sector)    End (sector)  Size       Code  Name
   1            2048           18431   8.0 MiB     EF02  BIOS boot partition
   2           18432        20989951   10.0 GiB    8300  Linux filesystem
   3        20989952        29378559   4.0 GiB     8300  Linux filesystem

I just ran through an install with the following drive layout which worked without issues:
