So I choose "something else" in the installation disk allocation and tell it to use /dev/sdb1 for boot, /dev/nvme0n1p1 for swap and /dev/nvme0n1p2 for the rest. I want to move /home onto the new SSD as well so I won't specify a separate /home during installation, I can copy files over from the old /home when I've got the installation basically sorted. Then is it best to run update-grub on the old 19.04 or the new 19.10 installation? Or doesn't it really matter? -- Chris Green
