Hallo Hughe,

I recently installed Devuan Jessie i386 from the alpha2 netboot-iso
without issues, but I used an existing partition structure and had the
installer only format, label and assign the mountpoints.

Regarding your grub-install problem, I noticed that you have some kind
of an uncommon setup, with the installer stick (which usually does not
have a MBR) instead of a HDD at /dev/sda:

If you choose to install Grub to the MBR, I think in the very most cases
it makes perfectly sense to use the MBR of the first HDD by default.

In your case you'd have to enter the disk manually – the installer
provides an option for that.
