Mladen,
yes, the disk is recognized by BIOS, and also parted shows it (it says “unrecognised disk label”, but gives the SAMSUNG information). So I think it is just a matter of partitioning it. PureOS 2.0 itself doesn’t seem to see it during boot-up and therefore the system will not install automatically on it. I will try PureOS 2.1 in the next days.
